See our review of My Amazing Human Body . If you want something totally gross, check out our review of Grossology . We also have a review of Magic School Bus Explores the Human Body . Younger kids will enjoy making a macaroni skeleton from our craft exchange. We have links to some really neat science sites such as Inner Body .
Kids can explore and find out all sorts of neat facts there.
Tons of fascinating questions are answered at The Last Word . For general questions, you may find answers at Ask Jeeves . We try to explore all links to insure safety, but supervision is always the best protection. I guess my point is that with younger children, you can interest them almost always by appealing to their sense of self. Basic overviews and fun facts can reinforce their willingness and eagerness to learn about their bodies.
