Introduction

Welcome to Stage 4 of Science. We hope this book will show you how
interesting and exciting Science can be.

People have always asked questions about things they observed and

looked for answers to their questions. Have you ever wondered about any

of these questions?

• How do our muscles work?

• Why can we see ourselves in a mirror?

• Why do liquids freeze and solids melt?

• Why do we have day and night?

• Why do volcanoes erupt?
• Why does a lamp light up when you switch it on?

You will work like a scientist to find the answers to some of these questions.

You will also ask your own questions to investigate.

You will be able to practise new skills and check
how you are doing and also challenge yourself

to find out more. We have included a variety of

different activities and exercises for you to try.

We use science in our lives every day. You will

learn about some of the things that scientists

in the past discovered and invented. You will
also find out how some people around you

use science and how using science can help

or harm our environment.

We hope you enjoy thinking and working like

a scientist.
