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

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?

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 ...

How does the retina work?

When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!

Aurora Australis

Aurora Borealis, also called the 'Northern Lights' and Aurora Australis, also called the 'Southern Lights' are spectacular light shows that illuminate the sky. What exactly are auroras and how are they created? Learn about the role of the sun and the Earth's magnetic fields in creating these light displays.

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 ...
