Bones are a fascinating topic in this house! Whenever we find a dead animal on the property, the first thing that the kids want to do is dissect it and check out it's bones (which occasionally gets to happen, depending on safety). When we go for nature walks and stumble across a bone, it comes home with us until we can identify it. Once, my son actually found a fossil, which a museum told him was either a tooth or a claw!!
The Osteology Museum in Oklahoma City is the largest collection of bone-related exhibits in America. It's unique exhibits are a great tool for teaching anatomy, biological history, adaptation, or classification.
