Content/Methodology

Introduction

Teacher runs tap in classroom. Children watch and wonder why. Teacher questions children and establish what children know already about water. Teacher leads children with questions of how we could find out ourselves, what we already know, or how we could learn more.

Development

Set up laptop and data projector. Insert CD Rom and click on Al's Kitchen.

Select the following sections:

22: Cool it - observing what happens to materials when temperature is lowered
24: Does it dissolve in water - which materials dissolve or do not dissolve in water
27: Ice, water and steam

By using the mouse children can see experiments carried out on screen. These experiments show what happens to materials before and after the change process eg what happens to materials when temperature is lowered.

Section 27 shows different forms of water.

We see water: as a liquid ; as a solid coming out of freezer; as a gas coming out of a boiling pot.

We see how water expands when frozen; how water condenses; how water evaporates

Conclusion/Follow Up Activities

Fill plastic bottle with water and put in freezer. Observe what happens over time.
Dissolve salt in water. Leave to evaporate. Observe what happens.
Fill two different containers with water - one bottle and one saucer/plate. Observe rates of evaporation.
