The materials around us have different properties. They may be hard, soft, shiny, electrical conductors or heat insulators - and that's just a few!
Scientist and designers choose materials for their properties. We know that loud noises can damage our ears and that we sometimes want to insulate sounds so that they sound softer or quieter.
To find out which materials are the best sound insulators, we carry out an investigation.
Are you ready to use your science skills to take part in this investigation?
