What your skeleton does
Goal: State the four jobs of the skeleton.

Your skeleton does four jobs. It supports you, protects your organs, lets you move and makes new blood cells.
Tap each job to see the bones that do it.
Bone is living tissue. It is hard and strong enough to hold you up, but light enough for your muscles to move.
