Science at key stage 3 (Year 7)

Unit 7G: Particle model of solids, liquids and gases
Section 7: Reviewing work

Objectives

Children should learn:

how to make notes and summaries to clarify ideas
to summarise the particle theory in writing and drawing

Activities		Outcomes
		Children:
Ask pupils to make annotated drawings to describe the arrangement and movement of particles in solids, liquids and gases. Ask them to choose two of the experiments they have carried out, or have seen, and describe what they did, what they observed and to explain their observations in terms of the particle theory.		draw and describe particles in solids, liquids and gases in terms of the movement and proximity of their particles describe observations they have made and explain them, eg a metal block is heavier than a wooden block because the particles are heavier or because the particles are closer together

Points to note

Many pupils will need more time and practice to grasp these ideas. They are revisited in many units - see 'Where the unit fits in' at the beginning of this unit.
