String Telephone Investigation

This is a fun activity where the children will use the string telephones they have made to investigate how sound travels through solids. The main activity is best suited to be done outdoors, in pairs or threes. The children are firstly encouraged to make predictions on whether sound can travel through a number of solids and liquids. This part of the lesson can be done by teacher demonstration while the children discuss and predict what will happen. This leads to a practical investigation to find out how, (and if ), a string telephone works!
