We’re currently learning about sound in Science, so yesterday we conducted an investigation into how sound travels. We used wire coat hangers and string to make Ear Gongs! Here are some photos of the investigation in action:

But how do these Ear Gongs work? When the coat hanger is gently banged against a surface, it causes the coat hanger to vibrate. These vibrations travel up the string which is tied around your fingers. When you put your fingers in your ears, you’re able to hear the sound more clearly – much like a stethoscope in a doctor’s surgery. The sound we heard was very surprising!! We really enjoyed this investigation and can’t wait to find out more about sound. ♬♪
