Year 5

Solids, liquids and gases have different observable  properties
and behave in different ways
(ACSSU077)

Chemical Sciences

  • recognising that substances exist in different states depending on the temperature
  •  observing that gases have mass and take up space, demonstrated by using balloons or bubbles
  • exploring the way solids, liquids and gases change under different situations such as heating and cooling
  • recognising that not all substances can be easily classified on the basis of their observable properties

Grade 6

Changes to materials can be reversible or irreversible

Chemical Sciences


  • describing what happens when materials are mixed
  • investigating the solubility of common materials in water
  • investigating the change in state caused by heating and cooling of a familiar substance
  • investigating irreversible changes such as rusting, burning and cooking
  • exploring how reversible changes can be used to recycle materials
  • investigate reversible reactions such as melting, freezing and evaporating
