Students recall circuit symbols and compare parallel and series circuits. Students will need to explain how LDR's, LED's and diodes work and can be used in everyday applications. Students demonstrate an understanding of mains electricity and the National Grid. Finally, students should be able to describe how different domestic appliances transfer energy from batteries or ac mains to the kinetic energy of electric motors or the energy of heating devices.

Discussion about the importance of not interfering with electrical equipment without proper training to ensure the safety of ourselves and others.
Importance of obeying 'danger of death' signs at substations and in buildings
Moral responsibility of reporting potential hazards; development of social skills by working together to collect data that will allow students to reach a conclusion.
Debate about the use of alternative fuels to provide energy to households.
If we all continue to demand more electricity this means building new power stations in every generation – but what mix of power stations can promise a sustainable future?
Maths: changing the subject, converting units, interpreting graphs
History: the development of industry and how that leads to demand for fossil fuels
Geography: the impact of the national grid on the environment, town planning
