What do elastic bands, straws and balls of bluetack have to do with how our body moves? This lesson looks into the machinery of the body, using artistic methods to give a visual insight into the hidden workings of how muscles and joints move and act under different conditions. Students will see what a torn hamstring actually looks like below the skin; the processes that actually go into moving their leg to kick a football; and why a knee moving sideways rather than forward and back can lead to a serious injury.
