Astronomy for sixth-graders: help on presentation?

You have some great ideas. Don't use those big boring words though. Constellations are good. Do you have sky charts to give them to take home? Tell them about stuff they can find in the sky on their own that nite. Is Jupiter still visible? They probably know about rotation, revolution & gravity. And that the earth is very much smaller than the sun. Didn't you learn that stuff in 2-3 grade? I did. Talk about NASA and space exploration, include past, present and the future. Also, the chance that there is life out there somewhere. How far are these other solar systems and how long would it take to travel there. Comets, asteroids etc. are also interesting. Do you have pictures? Pictures that can be diplayed on a screen, on an overhead projector or through a computer display. My astronomy teacher in highschool was an astronomer. He had a small observatory set up in his backyard and used his own photos in cl. Ask them what they want to know.
