This short clip demonstrates how body parts can be used to make different kinds of sound. It is ideal for use as a lesson starter in KS3/4 science. A physicist makes sounds using different parts of his body. He claps, pops his mouth using a finger, slaps his face and blows air though his mouth. These actions are then played back in slow motion. The question for students to consider is: How are the sounds being made? See the accompanying teachers' notes for a full explanation of the science underpinning the demonstration, plus suggested extension activities.
