National Geographic's Project Noah

Project Noah - to be honest, I'm not exactly sure what this does besides the fact that it does have educational components and some golly-gee factor, per norm for Nat Geo stuff. I think, though, that especially if you're a teacher or homeschooling parent who wants his/her kids to learn more about nature, this would be worth signing up for and looking into. I've just not had the time to explore it much yet since my sister introduced me to it yesterday.
