Curriculum content descriptions

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

Cold Metal

This activity invites students to investigate why, when you touch a variety of materials, some will seem warmer or colder than others, even when they're at the same temperature. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students ...

Convection Currents

This activity invites students to explore convection currents in water. Warmer water rising through cooler water bends light, allowing students to project its motion onto a screen and observe the flow. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying ...

Water-Bottle Membranophone

This activity invites students to make a membranophone, an instrument that produces sound from a vibrating stretched membrane. The activity includes a list of tools and materials required, assembly instructions, what to do and notice, an explanation for the underlying science of what students observe and suggestions for ...

ABC News: Sound waves measure ocean temperatures

View how scientists use underwater sound waves to measure ocean temperature changes in the Indian Ocean. The animations show how the technology called acoustic thermometry works. Australian scientists are working with a global network of 'listening posts' to monitor the long-term effects of climate change on ocean temperatures.

Colourful Weather, Ep 3: Why sunsets and sunrises will never be blue or green

Can you guess how many sunsets and sunrises an astronaut on the International Space Station sees every 24 hours? Sixteen! Imagine seeing all those spectacular colours so many times a day (even if the view lasts only a few seconds as they zoom by). Find out exactly why sunrises and sunsets are red, orange and golden but ...

Light takes time to travel through space

Light travels in waves and carries information as it moves from one object to another. In this clip, people are used to represent the Sun, planets and light rays in order to show that light takes time to travel through space bringing information from those objects to us on Earth. Discover that by the time we receive this ...

The physics of invisibility cloaks

Could an invisibility cloak actually work? Prashanth and Maria from MIT explore this idea and demonstrate the cool ways that light bounces, bends and mixes. How do the wings of the Morpho Butterfly give clues about how an invisibility cloak could work? How would light need to be channelled in order for something to seem invisible?
