This lesson introduces students to bones and joints. It discusses how Jeremiah was able to move away from a falling tree branch by the movement of his bones and joints. Students examine a real shin bone to understand that while bones are hard, joints allow for movement. The lesson introduces various joints of the body through riddles and has students label the joints on a skeleton diagram. It concludes with a fun activity that rewrites the lyrics of "The Skeleton Dance" song using proper bone names.
