This Year 4 Which Material Makes the Best Sound Insulator? Results Worksheet helps pupils investigate which materials are the most effective sound insulators by measuring and recording the volume of a sound source when wrapped in a range of materials. Pupils can complete this activity independently, in pairs, or as part of a small group, with plenty of opportunities to discuss their predictions, observations and results. This task encourages the use of scientific enquiry and mathematical skills, including measuring accurately, recording data systematically and comparing results to identify which materials are the most effective sound insulators.

This activity works brilliantly alongside our Year 4 Which Material Makes the Best Sound Insulator? Investigation lesson.
