explain observable properties of solids, liquids and gases by modelling the motion and arrangement of particles (AC9S5U04)

Elaborations
  • classifying substances as solids, liquids and gases and investigating their properties
  • exploring examples that demonstrate that gases have mass, such as blowing air through straws to move objects or using a balance to compare an empty balloon to one filled with air
  • using role-play to model the arrangement and motion of particles in solids, liquids and gases
  • observing a virtual demonstration of coloured gases being compressed and providing an explanation for the change in colour intensity
  • exploring, through guided discussion, ideas about what is between particles
  • recognising First Nations Australians’ knowledges and understandings of solids, liquids and gases and how these knowledges are applied in a range of processes and practices, including the extraction of oils, medical therapies and cooking
General capabilities
