Presentation: ideal fluid flow

When this pump or vacuum system is started, air begins to flow through this hose, which has a slight crimp, and as a result this hose begins to totally collapse. Now don't you say it's because of suction, because as you know, physics don't suck. (It blows.) (Video link: "hose collapse.")

In a previous presentation we investigated the behavior of static fluids, now we'll consider dynamic fluids--more specifically, ideal fluid flow. First we'll define what we mean by "ideal" fluids, then we'll see how two conservation laws are applied simultaneously to flowing ideal fluids.

Ideal fluids fall under a restrictive class of fluids--let's take a look at the characteristics that set ideal fluids apart from, say, real fluids.

Ideal fluids are incompressible, which water is to some extent. Note that while air is not incompressible, there are situations where we can make the crude approximation that it is.

An ideal fluid should undergo laminar flow, where the adjacent particles flow smoothly past each other, as opposed to turbulent flow, where particles swirl around in a chaotic manner. Like many fluids water can undergo both laminar and turbulent flow, so we'll restrict our attention to certain conditions where water undergoes laminar flow.

Lastly, an ideal fluid should be non-viscous, that is, flow without appreciable frictional losses, as opposed to a viscous fluid that, well, looks and is literally, "gooey." (Video link: "Viscosity.")

Streamlines are a way to visualize ideal fluid flow. Here air is undergoing incompressible, laminar, non-viscous flow over the front end of a car in this wind tunnel, where the streamlines are smoothly conforming to the contours of the car and to adjacent streamlines. Note the rear of the car, where the streamlines are turbulent, and indicate the presence of non-ideal fluid flow. (Video link: "Mercedes-Benz SLS AMG Developement and Testing Wind tunnel.")

The first conservation law for ideal fluid flow follows from its incompressible nature.

Even if a pipe changes radius, the incompressibility of an ideal fluid means that the same volume flowing in one end must equal to the same volume coming out the other end in the same amount of time. "Stuff in, stuff out."

This conservation of volume flow rate can be reinterpreted in terms of cross-sectional areas and fluid speeds in the continuity equation. A large-area section of pipe will have a slower fluid speed than a small-area section of the same pipe, which will have a faster fluid speed. Note that the product of cross-sectional area and fluid speed at any section of a pipe results in the volume flow rate.

For a pipe with a constant cross-sectional area, the speed of the fluid through this pipe is constant as well.

For a pipe with increasing cross-sectional area, the speed of the fluid through this pipe must have a corresponding decrease, such that it flows more slowly through the widening portion of the tube.

Conversely, for a pipe with decreasing cross-sectional area, the speed of the fluid through this pipe must have a corresponding increase, such that it flows more quickly through the narrow portion of the tube.

The second conservation law for ideal fluid flow follows from its laminar, non-viscous nature, as energy per volume density will be conserved if there are no losses to dissipative turbulence and frictional losses. (Incompressibility matters here too, such that the volume term in the energy per volume will be conserved.)

Bernoulli's equation is the extension of the static fluid relationship between pressure and gravitational potential energy per volume changes, to ideal fluid flow, with the addition of a translational kinetic energy per volume term. All three terms have equivalent units of Pa or J/m3, such that they can transfer to/from each other, as long as the net balance of exchanges is zero.

For an ideal fluid flowing through a horizontal pipe with a widening cross-sectional area, does the kinetic energy density term (1/2)·ρ·∆(v2) term increase, decrease, or have no change? (Refer back to the continuity equation discussion to determine this.) Does the gravitational potential energy density term ρ·g·∆y term increase, decrease, or have no change?

Then as a result, does the pressure of the ideal fluid flowing through this pipe increase, decrease, or have no change?

For an ideal fluid flowing through a horizontal pipe with a narrowing cross-sectional area, does the kinetic energy density term (1/2)·ρ·∆(v2) term increase, decrease, or have no change? (Refer back to the continuity equation discussion to determine this.) Does the gravitational potential energy density term ρ·g·∆y term increase, decrease, or have no change?

Then as a result, does the pressure of the ideal fluid flowing through this pipe increase, decrease, or have no change?

(Note that the pressure should decrease in the narrow portion of this pipe, which is why the crimped hose at the start of this presentation collapsed--as air flowed narrow crimped portion of the hose, its speed increased, which made the pressure decrease inside the hose, and the surrounding atmospheric pressure then flattened the crimped portion even further.)

For an ideal fluid flowing through a descending horizontal pipe with a constant cross-sectional area, does the kinetic energy density term (1/2)·ρ·∆(v2) term increase, decrease, or have no change? (Refer back to the continuity equation discussion to determine this.) Does the gravitational potential energy density term ρ·g·∆y term increase, decrease, or have no change?

Then as a result, does the pressure of the ideal fluid flowing through this pipe increase, decrease, or have no change?

Online reading assignment: fusion, nebulae, star cluster ages (SLO campus)

Astronomy 210, fall semester 2014
Cuesta College, San Luis Obispo, CA

Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.

The following questions were asked on reading textbook chapters and previewing presentations on fusion, nebulae, and star cluster ages.


Selected/edited responses are given below.

Describe something you found interesting from the assigned textbook reading or presentation preview, and explain why this was personally interesting for you.
"Hydrostatic equilibrium--I like the cheerleading analogy because it helped me understand the main concept."

"The 'House Party' model was a pretty clever way to describe stars and their turnoff points."

"There are only three colors emitted by nebulas."

"Fusion was interesting to me because I drive a Ford Fusion."

"Smaller stars will live longer...what? I would have thought that bigger stars would live longer."

"How much the pressure can differ from a large star to a small star. also found it interesting how much pressure and heat have to do with fusion."

"How stars can take hydrogen and change it into helium and energy! Just blows my mind, plus how these elements are made, making planets and life. Never thought of it this way."

"The process of nuclear fusion is interesting because it's where all elements in the universe originate. We're all stardust, man."

"The way an emission nebula works is the same way a neon light works...wow, mind blown!"

Describe something you found confusing from the assigned textbook reading or presentation preview, and explain why this was personally confusing for you.
"Turn-off points confused me very much. I had trouble comparing the 'house party' model to it."

"Hydrogen fusion deeply confuses me. Everything about it. The words are hard to understand and the concepts just don't click with me."

"The mass-luminosity relation because I don't understand it."

"As stars leave the main sequence category, does that mean they die? Since all of their hydrogen in their cores leave when leaving the main sequence then what happens? Just made me ponder while reading the section."

"Telling which nebula is which is confusing because I mix up colors a lot."

"What created the interstellar medium and how is it possible for it to form into a star?"

Fusion requires high temperatures in order for nuclei to move quickly enough to:
break heavy elements apart.  ** [2]
create convection currents.  * [1]
overcome gravity.  *** [3]
overcome repulsion.  ************************** [26]
(Unsure/guessing/lost/help!)  *** [3]

Briefly explain why "cold fusion" (producing energy from hydrogen fusion at room temperature) would be implausible.
"Under low pressures and temperatures, hydrogen does not get squeezed very much, and moves slowly, they won't collide with each other very much, or not at all. Not much squeezed, not much energy produced."

"In order for hydrogen fusion to work the protons need a lot of energy so that they move so fast they crash into each other and create energy. A room temperature atmosphere would not produce the need amount of energy."

"I don't understand the fusion section. please help."

"Because it needs heat, not cold."

Rank the fusion rates of these main-sequence stars (1 = fastest, 3 = slowest). (There are no ties.)
(Only correct responses shown.)
Low mass (red dwarf): slowest fusion rate [91%]
Medium-mass (sunlike): medium fusion rate [97%]
Massive: fastest fusion rate [89%]

(Only correct responses shown.)
Emission: pink [80%]
Reflection: blue [83%]
Dark: brown/black [91%]

Match the three different types of nebulae with their composition.
(Only correct responses shown.)

Early, or on time.  ****** [6]
When the most people should be there.  ****************************[28]
After most everyone has left.  * [1]

Ask the instructor an anonymous question, or make a comment. Selected questions/comments may be discussed in class.
"So what time is the house party? When would you show up to the party? Or does the party not start until P-dog arrives?"

When are we going to look through the telescope at the Bowen Observatory again?" (Next week, after the end of class. Weather permitting.)

"What are you doing for Halloween?" (Already done.)

Selected results/questions/comments are addressed by the instructor at the start of the following lecture.

The following questions were asked on reading textbook chapters and previewing a presentation on static fluids.


Selected/edited responses are given below.

Describe what you understand from the assigned textbook reading or presentation preview. Your description (2-3 sentences) should specifically demonstrate your level of understanding.
"Pressure is described as the amount of force exerted over a certain area on a surface. In regards to fluids, it can also be described as energy per unit volume. The energy density conservation equation is the sum of the change in pressure and the gravitational energy per unit volume. As one increases, the other decreases to balance the total to 0."

"Pressure is equal to force/area: it is an inverse relationship because if there is more area and the same amount of force, the pressure will be less because there will be more area for the force to push on."

"Pressure can be considered as the amount of force exerted over a certain area on a surface. It also makes sense that if you don't wear snowshoes, the force of your weight, distributed over the area of your feet will create a pressure that cannot be supported by snow and your feet will sink in."

"To calculate buoyancy of an object you only use the volume of the object that is submerged, so if whole object is under water than you use volume of the whole object."

"Pressure can be interpreted as force/area or energy/volume. The buoyant force on an object depends on the density ρ of the fluid, and the volume of the object that is actually submerged in the fluid."

"Forces in a container are under pressure because the molecules are contently moving even if the fluid is static. The buoyant force is basically like the normal force of water on an object."

"Pressure in air or water increases as you go down and decreases as you go up. This is what makes your ears pop underwater or in high elevations."

Describe what you found confusing from the assigned textbook reading or presentation preview. Your description (2-3 sentences) should specifically identify the concept(s) that you do not understand.
"No idea how to calculate buoyant force."

"Why does something that is almost weightless like air cause pressure at all?"

"Not super sure yet how we are gonna use pressure as a form of energy (density)."

"All of these new terms are definitely fresh, more exposure to them will help."

"In the case of the ascending weather balloon popping I'm not sure if the pressure inside increased or the outside."

What is the numerical value for atmospheric pressure (Patm, at sea level), in units of Pa?
"101,325 Pa."

"101.3 kPa = 1.013×105 Pa."

"1."

"Honestly, I just didn't get to it (yet)."

To three significant digits, what is the numerical value for the density of water, in units of kg/m3?
"1.00×103 kg/m3."

"999 kg/m3."

"1.00 kg/m3."

10,001.8 kg/m3."

"idk"

To two significant digits, what is the numerical value for the density of air (at 20° C), in units of kg/m3?
"1.2 kg/m3."

"1.2041 kg/m3."

"0.0012 kg/m3."

"idk"

P: increases [72%]

For the submerged diver floating underwater, Newton's __________ law applies, and the (downwards) weight force and (upwards) buoyant force on the diver are __________.
first; balanced.   **************************************** [40]
second; unbalanced.   **************** [16]
(Unsure/lost/guessing/help!)   ** [2]

For the red ship (barely) afloat, Newton's __________ law applies, and its (downwards) weight force, the (downwards) oil platform's weight force, and the (upwards) buoyant force on the red ship are __________.
first; balanced.   ******************************** [32]
second; unbalanced.   ********************** [22]
(Unsure/lost/guessing/help!)   **** [4]

Ask the instructor an anonymous question, or make a comment. Selected questions/comments may be discussed in class.
"Could we focus more directly on the math for this lecture?" (Sure, but I think we need to clear up a lot of definitions and concepts first.)

"Only six weeks of class left until finals?" (Whuuuuuuut?)

"I need time to think more about all this." (There are only six weeks of class left until finals!)

"I will learn this." (Yes. Yes, you can.)

"What is the class' average grade?" (Two weeks ago, just after the first midterm scores were posted, the average student total score was just under the "C/B" cutoff. But you're all going to improve your studying, after making your keep-quit-start resolutions, right? Right?)

I'm confused by everything in the book. I do not like that book. At all. My magnitude of happiness with that book is not large."

Describe something you found interesting from the assigned textbook reading or presentation preview, and explain why this was personally interesting for you.
"The fusion process--I think it is interesting to know what causes the heat and light from the stars."

"Mst stars are born at the same time but age differently."

"Stars have automatic pressure-temperature thermostats. These are used to regulate temperature and pressure so the star can maintain stability. I find this process really crazy!"

"Smaller stars will live longer because they conserve their fuel better. I would have thought that bigger stars would live longer."

"Nebulae between stars could create more stars itself."

"Pink clouds = hydrogen :)"

"Hydrogen is squished together to form helium, I had no idea this was possible."

"Different nebulae always appear as certain colors."

Describe something you found confusing from the assigned textbook reading or presentation preview, and explain why this was personally confusing for you.
"Hydrostatic equilibrium."

"Cold fusion."

"How mass could be formed into a star from the interstellar medium. What created the interstellar medium and how is it possible for it to form into a star? This was confusing because as I learn about astronomy many explanations for interesting things are vague or left out altogether making it confusing."

Fusion requires high temperatures in order for nuclei to move quickly enough to:

Briefly explain why "cold fusion" (producing energy from hydrogen fusion at room temperature) would be implausible.
"The gas must be very hot in order for the nuclei to have violent collisions and overcome the Coulomb barrier (repulsion), therefore room temperature would be implausible."

"Atoms all hate each other so the only way to make them collide and fuse to heat them up to millions of degrees so they're going so fast they don't notice before it's too late. They don't actually hate each other the charges of atomic nuclei just naturally repel other nuclei cause they're both mostly positive."

"The amount of energy required for fusion to occur would indefinitely raise the temperature, there is no way around it."

Ask the instructor an anonymous question, or make a comment. Selected questions/comments may be discussed in class.
"I realize that the sun fuses four hydrogen nuclei to make one helium nucleus, but why does some mass 'vanish' in the process? Also where does it go?"(Albert Einstein's E = m·c2 equation says that you can convert mass into energy; since the helium nucleus has less slightly mass than the four hydrogen nuclei used to build it, the energy released from this process came from the mass that 'vanished!')

"Are you throwing a house party? I'll bring cookies."

"A rolling object's translational speed v and angular speed ω are constrained via the "rolling without slipping" condition v = r·ω, so an object with a radius r that has a slow or fast translational speed must also be rolling with a corresponding slow or fast angular speed."

"That translational kinetic energy and rotational kinetic energy are different. I got that much."

"'For an object with both translational motion and rotational motion, it will have both translational kinetic energy and rotational kinetic energy'--I believe this concept needs a little more explanation before it sinks in."

Ask the instructor an anonymous question, or make a comment. Selected questions/comments may be discussed in class.
"Why does my spell check say 'translational' is not a word?"

"How is the rotational kinetic energy affected when the tire is in the air? Does it still meet that 'no slipping' requirement from before?" (No, it does not--which means that the angular speed of the tire will ideally be constant, even though the translational speed changes as it would for projectile motion.)

"Why do you not include any mathematical examples of the ideas in the blogs?" (That's what the textbook is for. The blog presentations are to emphasize the important concepts over the extraneous topics in the textbook that will not appear on quizzes and exams.)

"Can we go over specific examples for each type of energy showing when each energy increases and decrease? Examples using the rotational and translational equations would be helpful." (Yes, as time allows. Don't take too long with the "scratcher" group quiz.)

"I'm coming to class!!!!" (Uh, okay.)

Physics presentation: static fluids

In this scene from Man from Atlantis, Mark Harris (played by Patrick Duffy) is put into a water pressure chamber that simulates different depths, and watches as test canisters are crushed by pressures equivalent to 20,000 ft, 25,000 ft, and 30,000 ft below sea level.

On a more reality-based aside, consider tourists who float in the high salinity waters of the Dead Sea.

We'll discuss these two different aspects of static fluids here: pressure, and buoyancy.

First, pressure--as a force per unit area density, then reinterpreted as a pressure per unit area density.

Pressure can be consider as the amount of force exerted over a certain area on a surface, whether by a macroscopic object, or by the random bombardment by atoms/molecules of gases or liquids. If you don't wear snowshoes, the force of your weight, distributed over the area of your feet will create a pressure that cannot be supported by soft, unpacked snow, and your feet will sink in.

However, the force of your weight distributed over a much larger snowshoe area will reduce the pressure exerted on the snow, and you will not sink in much, if at all.

From the definition of pressure as a force per area density, the unit of pressure is pascals (Pa), equivalent to N/m2.

A more useful interpretation of pressure, especially in regards to fluids (gases and liquids) is to think of it as an energy per unit volume. Notice how the units of pascals equals N/m2, and when both numerator and denominator by are multiplied by meters (m), these units become N/m2 = (N·m)/(m3) = J/m3.

By interpreting pressure as a form of energy per unit volume, we can connect it to gravitational potential energy per unit volumeUgrav/V = m·g·y/V = (m/Vg·∆y = ρ·g·∆y, which also has units of J/m3.

Pressure and gravitational potential energy per unit volume are then terms in an energy density "conservation" equation, and they are allowed to "exchange" Pa provided the fluid is static and there is no external work being put in or taken out of the fluid. In this form, then by picking two locations in the same static fluid, an increase or decrease in the ρ·g·∆y must have a corresponding decrease or increase in pressure (∆P).

A weather balloon that is partially filled at ground level will rise, and will seemingly inflate and eventually explode at very high elevations. During this process, did the ρ·g·∆y increase or decrease? Did the air pressure outside the balloon increase or decrease?

Notice the full-sized Styrofoam™ cup in the back, compared to other cups that were carried in the outside storage compartment of a submarine, where the air pockets inside these cups were collapsed by the surrounding water, effectively permanently shrinking the sizes of these cups. During this process, did the ρ·g·∆y increase or decrease? Did the water pressure surrounding the cups increase or decrease?

Second, buoyancy.

The buoyant force on an object depends on the density ρ of the fluid, and the volume of the object that is actually submerged in the fluid. While this is a simple definition, knowing the appropriate amount of volume to use in this equation is key to understanding buoyancy.

For a fully-submerged object, the volume used in calculating the buoyant force is the volume of the entire object.

For a partially-submerged object, the volume used in calculating the buoyant force is not the volume of the entire object, but only the portion of the object that is actually submerged.

      ask questions to where i can see an example of each incident and be able to solve that problem.
      Get ready to know me well. Im gonna be asking a lot of questions.

everything
      I need to keep up with the reading assignments, homework problems, and coming to class so I can obtain as much point as I can to make up for my low midterm score.
      The reading is difficult a lot of the time I don't understand until you clarify. The homework enforces what you do in class but I have better success when you lecture first before I attempt the homework. The flash card questions are similar to quiz questions.
      I need to keep taking notes in lecture and keep doing the homework as well as start studying more and possibly getting outside help.
      Doing the extra credit, reading and homework assignment. Attention in the class. Working on problem and asking for confusion.

gettinglucky
      Well I don't know what I did, other than the questions seemed to line up with what I know. Hopefully this keeps happening for a while longer.

gotoclass
      Honestly, I struggle with this particular textbook- I don't find it to be very well laid out in terms of definitions, mathematical relationships, and examples in comparison to other science texts I've had. So, coming to class has been my main method of getting exposure to concepts.
      I can't succeed if I don't attend in the first place.
      I should keep going to class because the practice problems given during class time are helpful.
      I intend to KEEP coming to class consistently so that I absorb material from the lecture and examples, and so that I can take advantage of peer learning offered in class.
      I intend to keep going to class to reinforce the ideas and topics discussed in the book.
      I find the blog and the textbook interesting, but for me most of the knowledge I have picked up in this class has come from notes. There is something about visually seeing an explanation that makes a difference. Also having peers to converse with helps me sort out confusion.
      I've only missed one class and I intend to keep it that way, I know that if I miss a class I will have no idea what is going on, plus the book really isn't that helpful so its not like I can even read about it and catch up.
      I plan on attending every class possible to maximize participation points and get good example problems.
      continue to come to class every class
      It is helpful to see examples worked out on the board, and to get a little bit of exposure to the concepts we are expected to know. I wish the textbook and online presentations were as easy to follow; usually lecture is the only time I feel like I have a slight grasp on things. When I'm left to my own, I end up getting a little confused and a lot frustrated. Since I have little to no experience with this subject, I often don't know where to begin or even what questions to ask. I need a little bit of guidance, and showing up to class is the only way I can get a little bit of direction.
      I need to keep coming to the lectures, because it clarifies what I don't understand, and answers my questions. Plus, I get points toward my grade when I come to class.

homework
      I need to remember to take the survey quizzes for the reading and Homework assignments. I have an alarm on my phone to remind me now.
      i intend to keep onto of the homework assignments to be able to understand the concepts learned in class and know how to solve a problem in real life.
      If I complete assignments like homework and labs, I will keep up points in the class and be exposed to the material for the class.

interacting
      Im going to keep interacting on the questions we get asked during the class and discuss with my peers

keepingup
      By not staying behind, I wont need to relearn everything before an exam or quiz. This wil highly help me succeed.
      I need to keep studying the material and stay on top of doing the homework and the reading assignments. There are lots of little assignments, but the little assignments add up to lots of points that help in the long run.
      Need to better manage my time and procrastinate less to have time to better understand the material. And keep doing my study groups.
      I've found if I plan ahead and accomplish the homework ahead of time I understand more in class.
      Keeping up with the pace in this class is crucial. By doing homework on time, not only I get the points but I also understand the basic concepts that build up for more complex concepts in the subsequent classes.
      I intend to keep doing the homework and showing up to class. I feel like showing up to class really helps me patch the holes of things I don't get to a point that I am very comfortable with the material. The homeworks are free points so I will try to keep it up.

memorizing
      Keep memorizing the formulas.

organize
      When I have things organized it helps me focus better. For instance grouping things such as notes for quizzes and notes for midterms, I know what to focus on instead of getting confused.

payattention
      I intend to keep paying close attention in class in order to understand the material.

perseverance
      Since day one of this class I have maintained a work ethic equivalent to an "A" student.
      I give my all to every homework assignment, every exam and each lab. I am motivated to learn and have an insatiable appetite for knowledge.
      Honestly just putting the time and brain cells into the class is what's given me the grade I have.
      As long as i put forth the effort I will do well in this class.
      I just need to keep putting the time in studying and working out problems.
      I need to keep at my study habits and not stray too far. Even pick up the pace of what I am already doing so that I can exceed my own expectations.
      I just need to keep up my study habits and effort and more A's will follow on my tests.

preview
      I find the online presentations that are put together very helpful. Especially after I have attended the lecture on the material. Reviewing for the midterm by reading these presentations was also very beneficial.
      Reading about topics before they are discussed in class has made learning the material much easier. Normally, it is stressful and pressuring because I feel as though that when I put down the book I am suppose to completely understand it. By reading ahead and knowing we are going to talk about it in depth the next day, I am much more comfortable with the way we learn. I intend to stay ahead by reading early enough in the week so that I can learn at a comfortable pace and be able to practice as much as needed.

reading
      I will keep reading and studying every chapter in the book. I will also keep paying close attention in class. I will also keep doing well in labs.
      I intend to keep reading the chapters before each class as I feel like it helps me understand the lectures and example questions the next day in class.

review
      I'm going to continue looking at the online materials and explanations to what we go over in class and examine why each subject is the way it is.
      I tend to look over my class notes before a quiz or midterm in order to remind myself of what we went over in the days/ weeks prior.

studying
      Studying and learning the material on my own as well as it being explained in the class keeps me successful.
      plan better study habits, keep getting the homework assignments done.
      Read all notes, assigned readings, blog posts and work out all assigned problems.
      i underestimated the midterm. I need to study, study, and study some more
      although my study level is low and i havent been reading much of the chapters, i have done some of it. i intend tom improve myself on this point
      For test one I studied for around 7 hours and ended up getting a 75/75. So if I can keep studying that hard, I should be able to keep succeeding on the tests, and therefor, in the class.
      The amount of time you invest in something such as school will appreciate exponentially.
      I need to keep on studying and even though I did not do as well as I thought I would on the midterm, I need to prepare for the next one and continue to study.
      I need to review what i learned with someone that knows physics on a regular basis.

tutoringsessions
      I have been struggling in this class even with some tutoring once or twice a week. My plan is to review physics every day for a little along with some tutoring. If i keep looking at it daily I think it will become more clear.
      I have gotten a tutor in order to help better explain what I am having trouble with in this class.
      Hopefully be going to the Tutor lab to see if someone who knows this stuff can help me through problems

understanding
      In this class I feel like it is really important for me to not just "do" the work, but take the time to comprehend what I am doing as I go along. That way when I get a question I have not had yet, I am able to figure it out on my own because I have understood what I learned previously and can figure it out.
Quit word tags:
anxiety
      When I show up for an exam, no matter how much I have prepared and studied, I "FREAK OUT" at the moment I am taking the exam. I am taking steps to overcome this unwanted condition. I am reading studies on the subject and speaking to friends and professionals.

distractions
      If you're able to maintain concentration on school work and not become distracted you'll be able to do much better in school.
      end my netflix account.

everything
      what ever i was doing before was not working.

frustration
      Again, being honest here- I also struggle with this flipped-class idea. I'm just a student who prefers to come to the traditional class where I'm lectured to- that's how I learn best, at least with science and math classes. I struggle with it because I find myself not knowing what questions to ask in lecture, or what I'm expected to know (compounded by the textbook's tendency to show a plethora of mathematical relationships and concepts I don't hear about in class), because I suddenly come to a class where were expected to be more autonomous. I guess I just have to deal with it and get it done.
      I really don't like feeling confused. And, thus far, I've been very confused by physics. It makes me very frustrated when I can't understand something, and it makes me want to quit. Although I haven't (and won't) quit, I have allowed myself to get frustrated and not push myself further to try to understand. So I'll quit letting myself get frustrated.

missinghomework
      I've often forgotten or had trouble finding homework surveys.
      I need to remember to do the hw assignments because those points add up.
      in the beginning of the course I had trouble accessing the survey monkey website and didn't become accustomed to doing the homework before every class.
      I had trouble accessing the survey monkey website in the beginning of the course and didn't become accustomed to doing the homework the night before class
      I have missed the last couple of reading assignments and homework questions just because i forgot about them. I need to stop that before it becomes a habit.
      Missing out on the key stuff. Not practicing enough for the the test.

notaskingquestions
      I would like to quit not asking for help when I don't understand the material. I am kind of shy and I don't like to ask questions in class.

nothing
      There is nothing in particular that I want to change because I am pretty happy with how the class is going so far.

notunderstanding
      I believe that what I have the most trouble with is fully understanding equations, and I need to get a better grasp on all of the equations.

procrastinating
      I have been procrastinating or forgetting to turn in assignments or finishing lab write up.
      i intend to stay on top of what is needed to be done in this class such as homework, lab reports, and studying for quiz/test
      i usually procatinate alot on my physics homework and studying because i have alot of units this semester. I tend to lag in the subject because i feel like i should do more in class studying.
      I wait a long time to finish writing my lab reports. I think it's best to do them as soon as possible after the lab while the material is still fresh in my mind.
      I need to QUIT procrastinating in order to have enough time to do my assignments and learn the material the way it is laid out for me. This is a difficult one to overcome, as I work 40 hours/week and my main study space at home is in the living room of my apartment.
      I often procrastinate and wait until the very last minute to do the reading. This hinders me from really mastering the concepts. I notice that I have the right general idea but I cannot elaborate on these concepts because I have not put enough time in to master them.
      on the last exam I let the HW slide because I was busy with work and other classes. I still managed a 96% but was kinda stressed the weekend before.
      I have micro biology lecture and lab on Tues so I read but not as well as I should plus I feel rushed. I think rushing causes me not to retain what I should
      Procrastination habits keep me up late and stress me out before big assignments.
      I have a pretty big problem with getting distracted and pushing stuff till the last minute. I need to stop doing that and just finish assignments when they are first assigned.
      I need to be up to date in all my work. I need to read more of the text and try to compare all to what i learned in lecture class.
      I intend to not procrastinate as much on my homework in this class because I think it would really benefit me to have actually finished the homework before we discuss it in the class (which is the way the class is designed anyway).
      I am a huge procrastinator and wait until the day before tests and quizzes to study. I believe that this is one reason I am not happy with my grade thus far.
      Stop waiting until the day before classes to look at the homework and reading.
      I notice that if I do not look at my physics homework and notes over the weekend is very hard to remember small details. I tend to do my monday homework last minute on sunday evening. I need to start doing a little bit daily with a lot of detail and taking my time not just flying through it. If i stop doing things last minute it will greatly help.
      I tend to procrastinate on my studying, so I am not as efficient as I could be when studying for quizzes and exams.
      I need to quit waiting til the last minute to do the homework and need to stay on top of the reading and re read it every once in a while to keep it fresh in my mind.
      Stop being lazy and study the ideas and concepts more.
      I need to quit putting this class on the backburner and start putting more time and effort into really understanding concepts
      Putting off work till the last minute hurt because I don't always have the needed time to learn something.
      It is easier to retain information for me if I have reviewed it long before class.
      Stop leaving physic work till the last possible minute.
      I tend to skip the reading assignments until after lecture. I find myself falling behind in class now, and I want to stop that habit.
      I need to buckle down, and do what I need to do to get stuff done
      Although i do get the work done, procrastinating is a problem of mine... it just causes unnecessary headaches.
      This is something I am dealing with right now. I seem to do less urgent tasks then do physics till the last minute. I regret not finishing Physics with the other professor. I believe I was doing fairly well and completing the assignments, but I decided to find a job and work and lets not forget that the world cup was on as well. I dwell on the past and hurts me to think back about past mistakes about life.
      I need to do homework with enough time to really understand what I am doing.
      I need to stop waiting until a couple days before a quiz or test to really bare down and study.
      When I am doing my homework or studying I can get easily side tracked. I need to keep focused on the task at hand.
      When I wait until the night before a homework assignment is due to complete it, I always rush through the practice problems. I want to quit doing that and begin completing them the night before so I can be thorough with my understanding.

skimming
      I intend to slow down and take more time on the reading material. That way I can have a better idea of what is going on in class.
      Sometimes I find myself skimming when reading the assigned chapters or problems. This doesn't help me fully understand some concepts and I end up going back to understand better, actually wasting time.
      Sometimes I'll skim a hw question that is too difficult for me.

slacking
      Yep. Double negative. I haven't studied for a quiz yet and got a pretty horrible score on one, which shouldn't matter much in the end since a few of them get dropped. But I'd like to quit taking the quizzes so lightly and start studying for them harder so I can rack up them points!
      I sometimes don't try during the reading assignments. I read, but some of the problem questions that require work I don't do. And I need to because they help with understanding the chapter more.
      I've been in summer mode, and my grades show it. I need to stop being lazy buckle down and focus on this class so I can do well.
      Im going to quit overlooking the flashcard questions given during class and treat them more as test questions when doing them
      overlooking the flashcards and actually doing them more in depth.

working
      Cut my work hors down to 20 so that I have more time for studying.

worrying
      I worry about my grade too much. Right now I don't really have to, so that should help.
Start word tags:
alternatives
      While I understand the benefit to this pseudo-flipped classroom idea, I do not have the time to teach myself physics. I need some of these concepts (the majority of which are brand new material) to be explained to me. Since lecture is primarily devoted to working out a few examples, and the textbook has been less than helpful, I need to start finding other sources. I know I could benefit more from this class if I knew which questions to ask. Teaching myself physics has proved unsuccessful thus far, so I need to start putting effort into finding alternate resources.
      I will start reading other physics textbooks. I tried it for one chapter, and it helped a lot to clarify some of the material. I do not like the textbook that we use for this class, so I will start reading some other ones in addition.

askquestions
      Im gonna bring in the flash cards, and quiz reviews to prepare for test and quizes.
      I do the homework and reading, but then don't ask questions about things that I find confusing or difficult. I need to start getting my questions answered
      I need to get help from you (the teacher) or from classmates when I do not grasp all the material. Even when I understand the concepts I should broaden my understanding by getting more help.
      I find that I have lots of questions, but I don't usually think of them until after the professor has moved on from the topic he was discussing. At that point, I don't want to stop the lecture to ask.

believing
      I work a full time job due to my financial situation. Its really hard to be keeping everything i learn in track. But I keep believing that if there is a Will, than there is a Way.

diligence
      Start being more diligent about when and how much I study.

earlier
      I intend to start today. I need to stop procrastinating everything in my school life. I think I'll start tomorrow.

everything
      Read the book more and more, not only do the homework problems, but other problems, and maybe get a tutor.

flashcardquestions ("peer instruction," "think-pair-share")
      I am going to more carefully examine the flashcard questions and work out each one to practice and get a better idea of what might be on the next quiz.

homework
      I will start doing every homework assignment and extra credit opportunity
      I will start doing every single homework assignment and extra credit opportunity. I will also start to study harder and put more time into the class.
      I intend to START placing more emphasis on completing the homework exercises thoroughly, so that I can gain a better understanding of the fundamental concepts being taught, and the mathematical side of working problems in physics.
      I will work to be better at finishing more homework assignments before the class time and also before my study group. I think having my homework complete FIRST would help me to have more worthy discussions instead of feeling confused by concepts others already understand and I do not yet.
      If you start doing the homework and applying the knowledge you learn from the book and lecture it can only aide you in understanding the principles of physics.
      I will start paying more attention to each hw problem.

keepingup
      Setting at least an hour of physics studying every day. This will allow me to me to keep things I have previously learned fresh in my head.
      I have to keep at it and not fall behind.
      I need to study earlier before a test and every day go back through it all, so instead of cramming I'll have it all down to the point of just review.
      i plan on staying ahead of my studies.

maketime
      I intend to start setting more time aside for physics homework and study time so i can do better on quizzes and exams.

moreproblems
      Up until now, I have mainly focused on the conceptual aspects of the class, to the point where my math and problem solving skills are falling behind.
      I need to start working through more practice problems as I feel like thats what im struggling with the modt.
      I think if I can work through these I learn more and I should send my answers to you for correction
      Doing practice problems helps get familiar with problems you see on the test. Doing more then assigned problems.
      Sometimes they're too complex/I'm too tired so I just give up. Perhaps I should try harder.
      I fell if i did more homework problems, i would of had more practice, and done better on the midterm.
      Working on previous problem and have mastery one the concept. To know complex Relations
      I have a whiteboard at home and I don't utilize it enough. I want to start drawing out these practice problems on my board every single time so that it will be illustrated in my head.

nothing
      Not really gonna change anything to be honest. I am happy with my grade and feel I am understanding all the material fine (except for one thing I totally missed on midterm, but I get it now!).

organizing
      I need to start making a schedule for my study time instead of just studying randomly though out the day. This will keep my procrastination down and give myself goals.
      buy a planner.

payattention
      I usually study the day before quizzes or exams but tend to not focus in class. I sometimes understand better by self teaching because it helps me organize things better in my head, but don't understand some things, so paying more attention during class would probably help.

proactive
      I intend to be more proactive by doing the reading earlier, taking more time to understand the concepts, and seeking help when I do not understand something.

readmore
      Need to start doing more of the reading and pull apart the conce9ts more to better understand them, the math ksnt difficult, but the concepts are what i struggle with.
      I know that I haven't done the reading to the level that I need to in order to understand everything that is going on. I also need to study the information week by week instead of waiting until right before a quiz/test
      I need to read all the pages for the chapters in the book that correspond to what we are learning.
      i need to start really reading the material instead of just skimming it and moving on to the homework
      Reading and understanding the material by myself
      read the book a second time after the lecture to better understand the material.

reviewnotes
      I think going over my notes will help me retain the information better and hopefully I will do better on the quizzes.

selfstarting
      Kind of building off what I just said, the "real world" expects people to be self-starters in a lot of lines of work, so I guess I can't complain too much about the flipped-class thing. I came into this class being kind of excited about physics, since a lot of my experience has been with chemistry I thought it'd be enlightening to learn about how objects I can actually see interact and all the rest- but I find myself disappointed by counter-intuitive concepts. I talked to my brother about it who is a mechanical engineer and he said from his experience only engineers seemed to enjoy physics when he was in school. So, if nothing else, becoming more autonomous with my learning could make other future schooling easier.

studybetter
      I find that going to places like the library helps me study more effectively

studygroup
      I've made a few friends in the class and we work well during lecture, but we should start meeting outside of class in order to study

studymore
      I need to spend more time with the material in general. Doing more practice problems.
      i generally don't feel the need to study but don't always get the best results so i will begin studying concepts i am not confident on
      i intend to work alot harder in the second part of the semster since i have been laging way too much in this specific course. i also skipped alot of the homework during the first part of the semester, which i did my best to catch up on before the midterm 1 however, it did not help much. now i will do it sequentially and try and understand all i do better insteadof rushing through it.
      I skim the book but I don't read in depth.
      I need to study more than I do right now and actually ask more questions in and out of class.
      need to start studying more and going over the material more. If i looked at the notes more often and just ran through them, that would be better than nothing as far as familiarizing myself better with the material and some of the equations.
      Working harder toward success in this class is starting to be important, because I am on the verge of an A, and I need to pick up the pace if I want to end up with an A in this class.

takenotes
      Take far more in class notes, and notes from the assigned reading and blog posts.
      I am probably going to start taking my own notes from the book as i read it.

tutorsessions
      I have signed with a tutor with the hope that it will help in overcoming the "Test Anxiety".
      I plan to start using my tutor to help me have more success with studying for this class.

Keep word tags:
everything
     Midterm 1 came around and my points total to 304 or something like that. Halfway to an A and halfway through the semester seems good to me so I plan on keeping up what I'm doing. I've completed all the work and if I max out reading assignment points I will still follow along with them to understand course material. I'm satisfied with my grades on quizzes and the midterm as I'm halfway to the A I desire. Keeping in mind the Reading Assignment maximum and potential fall off of nice extra credit I'm pretty sure the final will be worth about 100 points which be more than enough to make up for it if I'm just as successful on it plus i have to study for midterm 2 anyway.

flashcardquestions ("peer instruction," "think-pair-share")
     I print out the flashcard questions and work through them. It takes a long time but it is worth it.
     I have printed all of the quiz and midterm flashcard questions, and I have made some of my own flashcards with definitions. I go over them when I'm in between classes and occasionally on the weekend. The flashcards really seem to help. I know the information, its the anxiety I get when I'm taking a test that messes me up.
     I intend to keep printing out the quiz flashcards and previous mid-term exams to study for quizzes and mid-term exams.

gotoclass
     Attending and doing these online things seem to be sufficient to keep me in a high grade. So I'll keep showing up and occasionally ditching out on these surveys.
     I missed a few classes this semester and my lack of attendance mixed with a hectic schedule and not-so-good planning/studying on my part has affected my grade much more negatively than I anticipated for this subject. So I'm going to keep attending class and work extra hard to earn a higher grade.
     I'm going to continue to come to class so I can get all my points
     if i continue to not miss amy classes, i will have done all of the in-class activities and have learned what is explained in class better than in the book, and also benefit from talking to peers whom might be able to better clarify if i am confused by something
     If continue to attend the rest of the classes, I will not miss any in class activities or quizzes.
     All the powerpoints are online so it would be easy to miss class here and there but going to class help me better understand the material.
     I find attending class extremely important. Being able to participate in group activities and hear how my fellow students process and understand concepts helps me understand them as well.
     I intend to keep attending class because I do not want to miss any information that I learn in class and I am going to continue studying because unless I study, I will fail everything.
     I wont miss any class and I will continue to complete online surveys.

homework
     I plan to keep doing my reading assignments and studying for quizes.
     i have always done the online assignments and the group work assignments which seem to help me if I dont do good on the quizes.
     Homework to keep up with reading and passing the quizzes as well as attending class to do in class assignments and quizzes and tests. Plus the quick lectures that expand on the readings.
     Reading the material from the book really helps to put the topic in order before learning about it in class. It is helpful to know the basics of the subject prior to the in-class time.
     I have done ever single homework assignment and I need to keep doing that to get my grade up.
     These online surveys are easy points in the class, and give a good, brief preview of what next class session is going to bring.
     Completing the homework and attending class.
     Doing the homework helps me be ready for the in class discussion which leads to greater understanding of the material.

inclassactivities
     One of things I believe helps me the most in this class is working in groups on in-class activities. I feel like this is where most of my learning takes place as I am able to think through, practice, and discuss the material.
     I have gone to all of the classes so far this semester, and completed all of the in class assignments. I intend to continue to do this because it definitely helps my grade.

keeping up
     Sometimes i forget to do the pre-lab as i tend to get bogged down by other homework and extra curricular activities so it is important that i stay on top of that. Secondly it is important that i keep showing up to class because as we get further and further into class we continue to cover more and more subjects but a Wednesday night class from 6-830 is so easy just to blow off.

officehours
     I am going to continue going to the office hours because it is a very helpful way to review information and get immediate answers to my questions.

practicequizzes
     The practice problems really help for being prepared for quizes
     It helps me to look over the practice quizzes we take in class and that are online.
     I will keep going over thw quizzes before an exam. It helped to pre test myself and have you look over it.

reading
     Keep reading, doing the assignments on time.
     Although it' really tempting to not read the book, I know that the information is really helpful in understanding the concepts. Plus, it's interesting.
     I need to maintain my self-discipline abd read each chapter in order to keep doing well on the quizzes.
     I intend to keep reading the textbook and the power points and try and take as many notes as I can in order to help myself strive to do even better in this class.
     I have found i get a better understanding when i read through the assigned reading and take notes. This helps me because if i get confused in class i can look over the notes i took out of the text book and it helps me understand better. Taking notes on the presentations also helps me
     I need to read the book more, and more often.

rereading
     I not intend to keep reading my textbook, but I hope to read it more in depth to gain a better understanding of the class so that I can succeed better in your class.
     it takes me a couple times to understand the material so I have to reread it.
     I need to keep rereading notes on the reading and from class.
     I find myself either not reading or jumping all over when I do read. This did not work so well on that last quiz.
     Days I spend reviewing the material before lecture help me a ton. After reading it once and reviewing it in class the material seems to stick a whole lot easier.

reviewing
     Just doing online assignments and taking notes without going back from time to time to review the material covered isn't the most helpful! Revisiting the material is what helps it stick!
     Constantly review the online presentations
     The blogs and book work helped me quite a bit on our first midterm. I did very well by reviewing that for a few days before the test.

studying
     What I mean by studying is actually studying. I am doing the required reading and taking notes as watching the PowerPoint blogs but after I take the notes I don't go back and read them like I should. I have to keep pushing myself to review something even when I think I know the material because studying is actually reviewing the material more than once.
     Make sure i pass the tests
     Studying for the midterm really made a difference in my confidence and earned me an A
     I am going to continue studying for the quizzes and tests, because it helps ingrain the information in to my brain.
     I quiz myself before every quiz which helps me understand the information plus know what kind of questions will be on the quiz.
     I want to study the material that's given online for us, and use it to study for quizzes and tests. The practice quizzes online are really beneficial for me.
     I am going to not only study for midterms, but also study for quizzes to ensure success.
     I intend to keep doing the work necessary to maintain a high grade.

takenotes
     Taking notes for both the reading and in class during discussions. Taking pictures of the worksheets are helpful too.
     I intend to keep note taking on the presentations before class as well going over the reading material to see if I can understand the concepts of the week before the next class session when it will be explained and clarified.
     Taking notes during class and about in class activities.

understanding
     To do this i go over the readig assignments or the presentations over and over to make sure the material sticks but i also know how to explain it when asked.
Quit word tags:
distractions
      I try to study in my apartment and then get distracted by the smallest thing

failing
      It's time to be a winner! (and not fail because I need to pass this class!)

groupfrustration
      I am going to stop being annoyed with group work because I can learn from others and we can help each other grow and learn and that will help lead to success in this class.
      Getting frustrated when I have people in my group who don't even try to help or participate in the group

napping
      Quit sleeping all weekend.

nothing
      I did not see this question, but as I said in my previous answer I'm satisfied with my performance in the class as is and if anything I'll study for quizzes and tests just a little bit harder as per necessary to get 300 more points. I haven't had to stress about this class too much.

nottakingnotes
      I rarely take notes, and have noticed that although I understand what you are teaching us while you are I often forget aspects of it later.

overconfidence
      The last few quizzes/ test, i figured i knew the material well enough to get a decent score, but clearly turned out the opposite. The questions that I don't go over are always the ones that come up, so i need to start studying a little more in depth, rather that thinking its just enough.

procrastinating
      I should start the HW thursday when I get out of class and not wait so long.
      I put off doing the textbook readings and online quizzes until the last minute because of my work schedule. Homework in general is at the bottom of my schedule. I really like this class and I plan to get a degree in medical science of some kind so the fact that I put fascinating homework aside for work bothers even me. I hate my job by the way.
      With work and school sometimes it's hard to either find time or find the energy to work on homework and study although it is very important.
      I plan to quit putting off the reading assignments to the last second.
      I always forget to do my homework until the last minute so have to semi rush
      Always putting off homework till the last minute isn't really helping...
      delaying homework
      I really wait to the last minute to do them... then I get stressed out.
      Tonight, for example, I was doing other stuff until 11 tonight, I NEED to stop this. IT doesnt benefit me at all
      I need to stop putting off the textbook reading until the last minute because then I don't read it as much and as thoroughly as I should.
      I do study but maybe i dont study enough of the material sense i wait too long and dont have enough time
      I need to get right on the reading and surveys so I can go over anything I'm unsure of a few times.
      Procrastination is my worst trait. I tend to put things off for a while and then try to cram at the last second.
      i need to stop putting off textbook reading and doing online assignments the night before they are due.
      I procrastinate with my readings, i intend to start reading them when we are assigned them to do
      I work a lot and when I'm not I try to go see my parents and end up doing homework late after work the day before it's due.
      I tend to put things off for as long as possible before cracking down the day before it's due... Not the best decision sometimes.
      Procrastination makes it hard to retain the information
      I need to quit procrastinating in some things and just get things done when I have them so I don't stress about it when I am completing it because then, I can't focus because I'm just worried about getting it done rather than how well I actually do on it.
      I know avoiding procrastinating when it comes to the textbook reading would help become more successful in this class. If I took the time to read and summarize the content in the chapters thoroughly it would help me to reinforce the material and be prepared to discuss it in class.
      Waiting last minute to study or do HW adds unneeded stress and is easily solved by just planning ahead
      Because this is only a once a week class I sometimes put it off knowing I have time till the next class.
      I always wait until the last day to do the reading assignments, which has led to me not completing a few of them. Not the smartest decision on my part.
      I just do all the homework and surveys on Tuesday night rather than looking at the material 3 to 4 times a week.
      I usually spend time with my family and then study or do the reading. If I can do the reading between classes I can do the homework earlier leaving more time for my family and studying.
      I tend to leave the reading for last minute.
      I intend to quit procrastinating on online assignments and studying for quizzes. I need to stop waiting until the last second to look at the material provided for us.
      Need to be prepared for class before class, have read material and have any questions answered in class, not right before a test.
Astronomy isn't as class where the information sticks in my brain, I need to start studying earlier.
      Remembering the homework the night before can be very stressful. Doing it a few days ahead is the way to go.
      If i read material periodically instead of all at once ill have a better chance of memorizing it.
      I intend to quit putting off studying and late night cramming to better retain information.
      I usually do the blogs late at night on the weekends so it's difficult to focus
      I intend to quit procrastinating because it seems that every week i tend to be cramming trying to get all my work/reading done by the 12 deadline. As you can see i am doing this at 11:13 at night right before it is due.
      No more doing the online survey on Tuesday. I want to get it done earlier so I have more time to focus on concepts I don't understand.
      I found myself crunching in the reading the night or day of class. Or sometimes ill tell myself i will read it later and then never do (only sometimes)
      I need to stop putting off reading the book more.
      I need to set aside more time so I am not reading my book late at night or just hours before class.

skimming
      I'm going to quit skimming the chapters and start reading them.
      Assume I'm smart enough to skim over everything.
      im gonna stop skimming the material and actually read it.

skipclass
      I need to quit having poor attendance, because I am taking this class to learn. I don't learn the information nearly as well when I teach myself, and there is really no point in me taking classes unless I attend them.

slacking
      I need to quit not-doing surveys because they're extremely easy and it's just lazyness and quite honestly I'm going to keep at it.
      I need to stop only doing my homework and make room to do other studies as well like studying for our quizzes and tests.

spacingout
      I get really distracted because the class is so late and I usually work an eight hour shift before class so I need o be as attentive as possible.

worrying
      I need to stop worrying about everyone else and how well they are doing in the class. When I start to compare myself to others, I panic and feel like I'm not as smart as them and I just get caught up in my emotions. Like during a quiz or exam, when I see people finishing and leaving and I'm not done yet, I feel like I need to hurry and not be the last one. So I need to stop thinking about everyone else and focus on whats in front of me in that moment.
Start word tags:
askquestions
      I need to ask more questions to my peers and you when i do not understand a topic
      Sometimes during class a question will come up and I will not ask it because I feel like it is too basic or too far in the past compared to what we are currently working on. I know I shouldn't hold back and should start asking any questions I have when they come up because other people may have the same question.
      If I have more questions I will stop being intimidated and ask for help.

bettergrades
      I really hope I can start doing a better job at taking quizes, ive never been a good test taker, but i really need to be.
      I need to get a good test grade because I cannot afford to fail this class.

betternotes
      I tend to focus mainly on the vocabulary terms and anything that appears on the study cards in the back of the textbook. I used to take very detailed notes in my high school AP classes. My notes for this class are not what I want them to be but again with the heavy work schedule i just don't feel like I have the time to make them what I want them to be.

earlier
      I procrastinate a lot of studying until the day before. It would probably soak in better if I started even one day sooner.
      I am going to start my homework as soon as class is done.
      i need to start being more consistent about getting the texbook reading done before the start of class.
      Figure out better times I could get my assignments done before out of class activities.
      No more laziness!
      I want to get started on studying the material that's provided for us earlier than the night before. Going over it a little each day is far more beneficial than trying to cram in one night.
      It gets busy with other classes and work to keep up with homework in this class sometimes..but i want to find a better balance of studying for this class. I do have a study group for this class but the studying usually takes place a couple hours before class.

extracredit
      Last time I left early to get some In-n-Out for my husband and myself, so I didn't stay for the extra-credit. Next I intend to stay for the extra-credit.

flashcardquestions ("peer instruction," "think-pair-share")
      I never really used the flash cards because it doesn't show the correct answers, but I should train myself to look over those and make sure I feel confident about my answers.
      I haven't used the flashcards yet, because I haven't felt the need, but they would probably be helpful.
      I haven't tried flashcards yet and think they could be useful.
      Study the flashcards, in class activities and old quizzes to really keep up on material.

gotoclass
      I am going to start coming to every class so that I can learn the information to my highest potential. I will not let anything get in the way of my Wednesday nights for the rest of the semester.

nothing
      What I'm doing is working quite well, I'm satisfied so far.

organizing
      I intend to improve my time management to increase the effectiveness of my studying.
      I need to be more efficient with my time and setting designated time for Astro. Id like to use the online resources more as well.

participating
      Because participating more will be helpful because being in groups is extremely frustrating and I'd rather be doing the work alone and figuring it out on my own, but I realize that for this class I have to change my preference and for that reason I will be even more active in groups than I already am

preparing
      I chose prepare because it can mean prepare for class, quizzes, or tests. I want to start spending more time on the reading to prepare for class discussions and activities. I want to start preparing more efficiently for quizzes and tests by downloading the flash cards and practice quizzes in advance.

previewlectures
      I plan to thoroughly read through the lectures and make sure I note what I understand and what I don't yet.

reading
      work in progress
      Reading the chapters completely.

rereading
      I feel like I go through the book okay. I skim a lot, and read interesting sections, but I should probably be more thorough.
      I need to make sure to read over the chapters more than one time to fully understand the concepts.
      I have been skimming the book and I know if I want to succeed in this class I need to thoroughly read it.
      I rely to heavily on the lectures to cover all the subjects that we will cover in this class bbut doing this has caused my quiz scores to drop so reading more would help to improve my overall performance in class.
      read a little more everyday

review
      I need to give myself more time in my day to review the material in advanced so I'm not behind!
      I hope to revisit chapter and/or specific subjects to gain a better understanding for the parts of the class that confuse me. I need to gain a better understanding in order to achieve more in your class.
      Review a day before the keywords and phrases from the reading assigned.
      Possibly review my materials more then once or twice, regurgitate the information on a more regular basis.

reviewing
      I tend to just read the information then do not look at it. I need to start going over the material, flashcard questions, old quizzes, etc. I AM going to start going over everything more often!
      Before quizzes I need to refresh my memory with the information learned over the previous weeks because when the quiz comes I sometimes forget the information.

sleep
      I need to start getting a better night's sleep in order to stay completely focused on what I'm doing in class or when I'm doing the reading.
      Sleeping more. It's a good thing.
      Sometimes i do not get enough sleep so the next morning i feel tired and cannot stay awake for class or don't want o get up and work on homework.

studygroup
      I think that having a study buddy for this class would be extremely helpful, though it's always a matter of finding a time that would work for the both of us. Hearing something explained to me through another person always helps.
      I need to start creating or getting involved with study groups. I think that will help me to bonce ideas and answers off others. My flashcard answers could be wrong because its just me, but having others i can compare too and work together to finding and understanding the right answer would greatly help. So I am going to try and get a study group together.
      I want to start studying with other people.

studying
      Putting more time and effort in studying before quizzes and exams.
      I'll start studying for quizzes. I haven't been studying for the quizzes and just rely on my memory.
      Quizzes take up a decent portion of the grade so it is important that i do well on them

studymore
      I do well but I could do better if I study more
      Well shucks I answered this in the previous question again. I'll start studying more as is necessary...
      I intend on studying even more for quizzes, midterms, and in general so I learn the information better.
      I need to study more often throughout the week to stay on top of this class.
      studying more creates ease on test and doing homework earlier in the week leads to greater chill time

takenotes
      The material that is gone over in class is valuable and I should probably be taking better notes to use as a study tool for tests and quizzes.
