1 Blue’s sound experiment

Today the children carried out a sound experiment as part of their topic on senses. The children used a plastic cup and a piece of string to see if sound would travel along the string.

Have a look at the short clip below to see how the children got on.

Challenge

-Repeat this experiment again at home and see if you can find another material that sound can travel along.
-Will the sound get weaker or stronger if the string is made longer?
