AC9S9U04 Year 9 Science

This Content Descriptor from Year 9 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

use wave and particle models to describe energy transfer through different mediums and examine the usefulness of each model for explaining phenomena

Elaborations

• 1 describing the processes underlying convection and conduction of heat in terms of the particle model
• 2 modelling the transfer of sound energy as waves using slinky springs and relating to the medium through which the sound is transferred
• 3 examining how the particle model of electricity explains static electricity and electrical current and relating this to voltage, conductors and insulators
• 4 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
• 5 investigating aspects of heat transfer and conservation in the design of First Nations Australians’ bedding and clothing in the various climatic regions of Australia
• 6 investigating the impact of material selection on the transfer of sound energy in First Nations Australians’ traditional musical, hunting and communication instruments
• 7 examining the forms of electromagnetic radiation that are used in different modern communication technologies and identifying any limitations
