Science at key stage 3 (Year 9)

Unit 9I: Energy and electricity
Section 2: b. How is energy involved in doing useful things?

Objectives

Children should learn:

that electrical circuits are used to perform a variety of useful tasks
that electrical energy is transferred around circuits and can be transformed in components, eg to produce light, sound, movement and heat
to identify devices and situations that act as energy stores

Activities		Outcomes
		Children:
Elicit from pupils' observations the conclusion that electrical energy is a convenient way to do many useful things. Recall pupils' year 7 work on fuels as energy stores and elicit other ways that energy can be stored, eg compressed spring - potential; flywheel - kinetic; battery - chemical. Contrast this with electricity, which cannot be stored.		describe the energy transfers and/or transformations in several toys or devices recognise that electricity is a useful means of transforming energy give examples of ways in which energy can be stored
