investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state (AC9S3U04)

Elaborations
  • observing the properties of substances and classifying them as solids (that hold their shape) or liquids (that fill the bottom of containers)
  • investigating ice melting or water freezing in a sealed bag and explaining their observations
  • using ice cubes, butter or chocolate to explore how changes of state involve the removal of heat or the addition of heat
  • investigating how changes of state in materials used by First Nations Australians such as beeswax or resins are important for their use
  • exploring how changes from solid to liquid and liquid to solid can help us recycle materials such as glass or plastics
General capabilities
  • Critical and creative thinking Critical and Creative Thinking
