For parents and teachers
Read what is said in the video (transcript)
What if you had no skeleton? Your skeleton is the frame of bones inside your body. An adult has about 206 bones. Job one: support. Your spine, or backbone, holds you up. Without a skeleton, you would be a wobbly jelly. Job two: protection. Your skull protects your brain, and your ribs make a cage around your heart and lungs. Job three: movement. Muscles pull on your bones. The femur is your longest bone. Joints, like your knee, let you bend. So remember: your skeleton supports you, protects you and helps you move. Can you find your ribs?
