Year 9 Physical Sciences Content Descriptions

Energy transfer through different mediums can be explained using wave and particle models (ACSSU182)

  • exploring how and why the movement of energy varies according to the medium through which it is transferred
  • discussing the wave and particle models and how they are useful for understanding aspects of phenomena
  • investigating the transfer of heat in terms of convection, conduction and radiation, and identifying situations in which each occurs
  • understanding the processes underlying convection and conduction in terms of the particle model
  • investigating factors that affect the transfer of energy through an electric circuit.
