In our Science, for our sound test, we were tasked with making our own string telephones and holding a conversation with our partners. We made predictions for each change to the string, whether it was pinching the string or joining a new line, ‘a party line’. We also tried different lengths of string to see if that made a difference to the vibration/ sound.
