Curriculum content descriptions
use wave and particle models to describe energy transfer through different mediums and examine the usefulness of each model for explaining phenomena (AC9S9U04)
Elaborations
- describing the processes underlying convection and conduction of heat in terms of the particle model
- modelling the transfer of sound energy as waves using slinky springs and relating to the medium through which the sound is transferred
- examining how the particle model of electricity explains static electricity and electrical current and relating this to voltage, conductors and insulators
- discussing the wave and particle models of energy transfer, including the concept of photons, and how they are useful for understanding aspects of light and other forms of electromagnetic radiation
- investigating aspects of heat transfer and conservation in the design of First Nations Australians’ bedding and clothing in the various climatic regions of Australia
- investigating the impact of material selection on the transfer of sound energy in First Nations Australians’ traditional musical, hunting and communication instruments
- examining the forms of electromagnetic radiation that are used in different modern communication technologies and identifying any limitations
