The Skeleton and Muscles — Interactive Lesson & Activities (Ages 11–14)

Can your students name the bones that protect the heart? This 45-slide interactive lesson teaches the skeleton and muscles, from function to labelling real bones.

Mastering the Skeleton and Muscles in KS3 Science

Students learn to understand the functions of the skeleton, explain its various features, relate images of bones, muscles and joints to diagrams and the body, and distinguish between vertebrates and invertebrates. They learn that the skull protects the brain, the ribs protect the heart and lungs, and joints such as knees and ankles are where two or more bones meet. A drag-and-drop activity labels named bones, including the vertebra, patella, fibula, phalanges, tarsus, pelvis, mandible and clavicle.
