Science K–10 (inc. Science and Technology K–6) - Stage 2 - Knowledge and Understanding – Natural and Made Environment Material World

Outcomes

A student:

  • ST2-12MW

    identifies that adding or removing heat causes a change of state between solids and liquids

  • ST2-13MW

    identifies the physical properties of natural and processed materials, and how these properties influence their use

Content

  • A change of state between solid and liquid can be caused by adding or removing heat. (ACSSU046)
  • Students:
  • describe some everyday situations where solids and liquids change state by adding heat (heating) or removing heat (cooling)
  • predict and observe the effects of adding heat or removing heat on a variety of everyday solids and/or liquids, eg butter, chocolate and water CCT
  • describe how scientific knowledge about the effects of heating and cooling is used by people in their everyday life, eg the types of clothes worn, the packaging and preparation of food and everyday devices, eg freezers, irons or cooktops
  • Natural and processed materials have a range of physical properties which influence their use. (ACSSU074)
  • Students:
  • observe the changes that occur in the physical properties of everyday materials when they are heated, cooled, bent, stretched, folded and twisted
  • observe and describe the structure of materials that can be seen with the naked eye and a magnifying glass, eg grains in bread, particles in chipboard or cork, threads within a fabric or fibres in paper L
  • identify the properties of some natural and processed materials
  • describe how a range of common natural and processed materials are used in everyday life
  • generate ideas about how the physical properties of some natural and processed materials influence their use CCT
