This week in Science we began learning about what makes Usain Bolt so quick as part of our Animals Including Humans topic.

We learned that to run fast we need really strong muscles and to be very physically fit. We discovered that muscles work in pairs to contract and relax, to enable our bodies to move. We also learned about two specific type of joint found in the human body; the ball and socket joint, and the hinge joint.

We then went outside with the iPads and struck a pose, then in small groups we labelled each of the muscles and joints we had used using the Seesaw app.

Take a look at our awesome work below.
