Muscular and Skeletal System Functions

The video lesson, led by Teacher Mirna Alkaroot for Grade 3 science, covers the skeletal and muscular systems. It explains how the skeletal system, made up of bones, supports, protects, and shapes the body. The muscular system, composed of muscles, works with bones to enable movement. The lesson highlights the importance of these systems and includes fun facts about the heart and bones. The session concludes with a review of the key points.
