Materials and their properties - what pupils should be taught

Changing materials

  • To describe changes that occur when materials are mixed, e.g. adding salt to water
  • To describe changes that occur when materials, e.g. water, clay, dough, are heated or cooled
  • That temperature is a measure of how hot or cold things are
  • About reversible changes, including dissolving, melting, boiling, condensing, Freezing and evaporating
  • The part played by evaporation and condensation in the water cycle
  • That burning materials, e.g. wood, wax, natural gas, results in the formation of New materials and that this change is not usually reversible
