Astronomy Resource - Universe at Your Fingertips
The Astronomical Society of the Pacific has a long history of compiling the best astronomical resources for teachers. For years, at professional development workshops we used activities from their "Universe at Your Fingertips" book, that required a 4" D-ring binder to hold. When we gave each teacher a copy, they were always appreciative until they had to pack the heavy binder in their luggage for the trip home. Well, the ASP has produced the Universe at Your Fingertips v2.0, and this time, they are distributing it on a DVD, so it is much more portable. It is probably the most comprehensive resource of its kind, and it is a great place to start if you are looking for an activity for any topic area in astronomy.
