Exploring Sound

Year 4 had a fantastic time exploring sound in our Science lesson. They used a number of different objects to experiment with sound. String telephones showed us how sound can travel when we speak into the plastic cup; the cup vibrates and the vibration extends into the string. We did the same with a slinky with string looped around our ears – this was fascinating! We had a chance to go outside and tap the railing with a coin or tuning fork. It was great to see how the sound traveled through the railings and reached each person at a different time (see video below).
