Y3 Muscles Move Bones – the Biceps and Triceps

Pupils learn that all muscles work by contracting (pulling) and that muscles cannot push. They learn that muscle have to work in pairs, while one muscle is contracting, the other one is relaxing. When muscles contract, they become shorter, fatter and harder. When muscles relax, they become softer, longer and thinner. They do this by studying the triceps and bicep muscles.

Learning Objectives:

  • PoS - identify that humans and some animals have skeletons and muscles for support, protection and movement
