Law of conservation of energy
  • Use the law of conservation of energy, and calculations, to explain that total energy is maintained in energy transfers and transformations in a closed system

  • Explain efficiency in relation to energy transfers

  • Explain how to improve energy efficiency in energy transfers and transformations

Sources of energy
  • Identify different types of energy sources

  • Describe how electrical energy can be produced from different types of sources

  • Evaluate the advantages and disadvantages of using renewable and non-renewable sources of energy to generate electricity, including efficiency, economical and technological considerations

Electrical energy
  • Identify the elements of a complete circuit

  • Construct circuits and draw circuit diagrams that contain several components to show the flow of electricity through a complete circuit

  • Measure and compare voltage and current at different points in series and parallel circuits

  • Conduct an investigation to compare the energy transformed over time in model circuits or appliances

  • Investigate the energy star ratings of a range of appliances and explain the criteria used to determine these ratings

Global future energy needs
  • Evaluate ways to optimise current energy use

  • Examine data to identify past trends in energy use, and predict possible future demands, at a state, national and global level

  • Explain reasons for the development of alternative sources of energy

Energy in context
  • Use data, evidence and research to evaluate the development of alternative energy sources to meet and reduce global energy demand
