Good Vibrations in Year 4

Today in Year 4, the children have been learning about how sound travels to our ears. To show how this works, we made string telephones which work by the vibrations from our voices travelling down the string to a receiver at the other end. The vibrations then make their way from the cup, into the air and then into our ear, hitting the ear drum.

We found that these worked best when the string is tight and the children weren’t touching the string.

A fun and engaging way to learn about sound. Well done Year 4!
