The following images are from presentations I have given. The first set is from the Phoenix Astronomy Society's Open House at the Arizona Science Center in March of 2003. I set up a display case with samples, a few books with lots of pictures, and an exercise in identifying 'rites and 'wrongs.
Next are some images from Mount Elden Middle School
in Flagstaff.
