Section 1: Introduction

QCA

Objectives

Children should learn:

Activities

Outcomes

Children:
Review children's understanding of solids, liquids and gases by asking them to draw a concept map using terms eg solid, liquid, gas, melt, freeze, water, ice, change, cool, warm, flow, change shape, volume, powder, evaporate. Discuss their maps with the children using specific examples to clarify what they know. Introduce the term 'state' to describe solid, liquid and gases.

Points to note

Teachers will need to take account of what this introductory work shows about children's knowledge and understanding of solids, liquids and gases in their short-term planning of later activities.

A concept map shows the connections between different ideas in a particular topic and is a useful source of information about children's understanding. Children will need to be taught how to make a concept map if they have not done so before.

Children may encounter the terms 'gas' and 'vapour'. At this stage it is not necessary to make a distinction between them.
