Movement

Pupils will learn that particles of substances move within, into and out of cells by diffusion.

Pupils learned that in multicellular organisms, all the tissues and organs are made of cells.

This unit investigates the structure and functions of the human skeleton, including support, protection, movement, and blood cell production. Explore biomechanics, the interaction of muscles and the skeleton, and antagonistic muscles while measuring muscle force.
