Scientists and engineers invent and design electrical appliances to help improve our lives.
Scientific ideas can be presented using labelled scientific drawings and diagrams.

Children may think that an appliance requires batteries and is not an electrical appliance as it is not 'plugged in' for use.

Ensure opportunities for children to consider a range of appliances and how they are powered by electricity to perform a function.

Electricity - Electricity is needed for lighting, heating and making machines and appliances work.
Electrical appliance - An electrical appliance is a device or piece of equipment designed to perform a specific task, which needs electricity to work.
Engineer - An engineer is a person who designs and builds things.
Diagram - A diagram is a simplified drawing of information.
