Through the following activities, pupils will learn:

  • that when some materials are squashed, pulled, pushed, turned, twisted or stretched the shape of the object will change
  • that forces affect different materials in different ways
  • to predict what is likely to happen when different materials are pushed, pulled, stretched or bent
  • to carry out an investigation based on their predictions and interpret the results

These activities can be used to address 2.3 and 2.4 of physical processes and 1.2 and 2.1 of the scientific enquiry programme of studies in the national curriculum for Wales.
