Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.

Sound-path record: an adult's cup-and-string model transmits a voice along a taut string. The medium here is the solid string. A medium is material that carries vibrations. Sound can travel through gases, liquids and solids. These are supplied models, not instructions to go underwater or put an ear against equipment. Adults prepare any cup holes; string stays away from necks and paths.
