4J make string telephones

Over the last 2 weeks, 4J has been making string telephones as part of the science topic of sound.

The children looked at how a string telephone worked by sending vibrations along the string. The children also looked at whether the string should be tight or loose and whether the length of string made a difference to the sound. Some children even discovered how to make a 4 way string telephone.
