Properties of Materials

Science Year 5 Music Festival Materials

The annual Spring Music Festival launches in just over 2 months and you have been selected to form the ‘materials committee’. Do you know your thermal insulators from your thermal conductors? Can you find the best materials for take-out bags and drinks bottles? You will need to carry out an impressive array of tests to identify which materials are up to the job for a variety of festival needs. Roll your festival sleeves up… you’re going to need to get your hands dirty!

Session 1 Food prep materials challenge

ii) Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic.

Working Scientifically

  1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
  2. Record data and results of increasing complexity using tables and scatter graphs.
