Sound in Year 4

In Science we have been learning about sound. On Friday, the children were learning how sounds travel. We began by completing some scratch tests to reveal which materials sound could travel through easiest. Then, we moved onto to making a string telephone. One child held the cup up to their ear while their partner placed the cup over their mouth and spoke into it. Through trial and error, we found the vibrations were able to travel through the string when it was pulled taught but not when the string was slack. Even the children who are learning at home had a go at making one too, testing it with their adults and discussing alongside the class during the live lesson what went well. Why don't you have a go too?
