too bad you don't have a planetarium. I hand my students big cardboard arrows and have some of them them stand near the planetarium horizon and PREDICT where the sun will rise/set. Then all the other students vote with clickers/ This seems to impress upon them pretty well. But it requires a planetarium :)

Thanks for all your good work!
