Curriculum content descriptions

Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer (ACSSU179)

Elaborations
  • investigating reactions of acids with metals, bases, and carbonates
  • investigating a range of different reactions to classify them as exothermic or endothermic
  • recognising the role of oxygen in combustion reactions and comparing combustion with other oxidation reactions
  • comparing respiration and photosynthesis and their role in biological processes
  • describing how the products of combustion reactions affect the environment
Cross-curriculum priorities
ScOT terms

Enthalpy,  Acids,  Redox reactions

Designing urban carbon sinks lesson

In this lesson, students learn about the role of vegetation as carbon sinks, conduct field work to evaluate local carbon sinks and explore urban design issues. Students asses their own carbon footprints using the carbon footprint calculator, learn about carbon offset, carbon farming and carbon storage programs. Students ...

A Little Atmosphere

This activity invites students to model the scaled thickness of the atmosphere on a globe using sheets of transparency material. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students observe and suggestions for further activities.

Oxyfuel combustion

This fact sheet describes oxyfuel combustion, the technology that burns fuel in almost pure oxygen. Because this makes it easier to capture carbon dioxide from flue gas, there is the potential to achieve near-zero carbon dioxide emissions from the production of coal-fired electricity. A diagram illustrating this process ...

Gas-fired power

Find out how gas-fired power stations work. This fact sheet describes the generation of electricity in gas-fired power stations, which typically produce 50 per cent less carbon dioxide than conventional coal-fired power plants. Information is provided about the Daandine Power Station located west of Brisbane, which uses ...
