Lesson details

Key learning points

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

Common misconception

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.

Keywords

  • 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.

Raise children's awareness of future electrical appliances which are in development and encourage them to think of their own creative inventions for new electrical appliances to make our lives easier.
Teacher tip

Equipment

None essential but images of, and access to, a range of electrical appliances would be useful.
