Our skeletons are made up of different bones. Bones are very hard and rigid. Minerals, mainly calcium and phosphate, make the bones hard. Milk and milk products have lots of calcium which strengthens bones. The bones in our skeletons have many jobs.
Some bones protect other parts of the body.
Our skeleton is literally a support system. It supports our muscles and gives us much of our shape. Without the bones in our skeleton, our bodies would collapse. Show a film or filmstrip which emphasizes the skeleton and the role it plays in supporting the body. Have the students examine a skeleton and compare the bones to a living person.
