Pupils plan an investigation to find out which materials are the most effective at sound proofing. They make predictions, investigate, record observations, present results and draw conclusions.
Learning Objectives:
PoS - identify how sounds are made, associating some of them with something vibrating
WS - pupils should make earmuffs from a variety of different materials to investigate which provides the best insulation against sound; make systematic and careful observations; set up simple practical enquiries, comparative and fair tests
