Astronomy in-class activity: star sizes

Astronomy 210 In-class activity 16 v.13.06.10, fall semester 2013
Cuesta College, San Luis Obispo, CA

Students find their assigned groups of three to four students, and work cooperatively on an in-class activity worksheet on applying Wien's law and the Stefan-Boltzmann law to determine the relative sizes of select pairs of stars.

(For the purposes of this in-class activity, the proportionality constant in the Stefan-Boltzmann law is omitted, as only relative rather than absolute values of star luminosities, temperatures, and sizes are compared.)
