WALA: The water cycle

WALA: The water cycle

L.O: to know that air contains water vapour and when this meets a cold surface it may condense.

Introduction

Review the previous lesson on condensation

Starter

Ask the class if they know that the water they drink might be the same water that Albert Einstein (or another famous scientist) drank, or perhaps even the dinosaurs. How 

is this possible?

The amount of water on Earth never changes. It keeps getting used over and over again.

Write the word ‘cycle’ on the board. Discuss these questions.

What do you think of when we read the word ‘cycle’?

What shape best represents a cycle?

Have you ever heard of the water cycle?

What do they know about it?

Have ever seen rain?

Where does rain come from?

How does it get into the cloud?

Ask them to think back to Activity 3.5b. Where did the water on the glass come from?

- The water cycle is the movement of water from the Earth's surface in the air and back again.

- In the water cycle,water evaporates from the Earth's surface, condense to form clouds and falls back to Earth as rain.
