Curriculum content descriptions

Energy conservation in a system can be explained by describing energy transfers and transformations (ACSSU190)

Elaborations
  • recognising that the Law of Conservation of Energy explains that total energy is maintained in energy transfer and transformation
  • recognising that in energy transfer and transformation, a variety of processes can occur, so that the usable energy is reduced and the system is not 100% efficient
  • comparing energy changes in interactions such as car crashes, pendulums, lifting and dropping
  • using models to describe how energy is transferred and transformed within systems

Catalyst: Nuclear fusion future

Visit the world's largest nuclear fusion reactor, which uses the same process as the Sun to produce energy. Look at the new advances in fusion technology which mean, for the first time, a fusion reactor should now be able to produce more energy than it consumes. It offers a future alternative energy source, but is not without ...

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!

Can photons and atoms generate laser?

Electrons around atoms can absorb and emit photons of particular colours of light – see three different atomic models explain what's going on.

How do solar panels work?

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. This TedEd animation (4:58 ...
