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

Elaborations
  • 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
  • exploring the properties of waves, and situations where energy is transferred in the form of waves, such as sound and light
ScOT terms

Sound,  Energy conversion,  Waves (Energy),  Electromagnetic radiation,  Heat
