Kids Know It
One website that I think is very useful is the Kids Know It Network. The site has many interactive games, movies, and even music. It is a site that allows students to self select according to their interests or teacher assignment. Links to other sites bring students on a real journey of understanding. I have used this for building background knowledge and student research while investigating the planets, constellations, and moon phases. The kids love it and don't want to leave the computer lab.
