Stellarium
Here is a great program for viewing the night sky that students may be interested in playing around with. There are several of these type programs on the Internet if you do a search. The one that we have been looking at in 3rd grade, and will in 5th also, is Stellarium. It is available at Stellarium.org. It can be downloaded to Windows, Mac, and Linux.
