A kid's site... Well that's a lot harder.\n\nNormally I'd suggest google, but I know that can be unreliable for the simplest of searches. I could direct you to wikipedia (see sources) but that's all very complex, university-grade stuff. If you can, check a textbook or better yet, a REAL, paper encylopedia. Good luck!
