I am going to go a little different on this posting. I had the opportunity to mess around with an IPad a couple of weeks ago. there is a great app called Star Walk. This app can be used on an iphone, ipod and ipad. The students can point it at the ceiling and see what constellation will be directly in the sky on that given day. As they move the device around it will show all stars, planers, and constellations, directly above them. It also has a home setting and it will tell you the sunrise, sunset, day length, and elevation of the earth and other planets. It is a great app if you have ipads, ipod touches, or iphones available to you.
