To generate electricity is to produce it.

Fossil fuels are fuels made over millions of years from fossilised plants and animals buried deep beneath Earth's surface.

Gases which contribute towards global warming are called greenhouse gases.

Global warming is a result of the processes that cause the average temperature of Earth to rise.

Sustainable sources of electricity are those which do not need to be replaced because they will never run out.

Sustainable sources of electricity (non-statutory)

Science

In the Changing circuits unit, pupils learnt to give reasons for variations in how components function, such as the brightness of bulbs. In the Series circuits unit, they will build on this knowledge to find rules for electric current and voltage in series circuits 

In the Simple electrical circuits units, pupils learnt to construct a simple series electrical circuit, identifying and naming its basic parts. In this Changing circuits unit, pupils will build on this knowledge to compare and give reasons for variations in how components in a circuit function
