Introduction
Welcome to Stage 5 of Cambridge Primary Science. We hope you will enjoy using this book
and find out how interesting and exciting science can be.
People have always asked questions about things they observed and looked for answers to
their questions. For example, in Stage 5 you will find the answers to these questions:
How does the body digest the food we eat?
Why do insects visit flowers?
How are sounds made?
How do satellites stay in orbit?
How do parachutes bring people safely to the ground?
What gases are in air?
Where does the sugar go when we stir our tea?
What causes the seasons?
How can mice escape from eagles?
You will work like a scientist to find the answers to some of these questions. You will also
ask your own questions to investigate.
We have included a variety of different activities and exercises for you to try.
Sometimes you will work with a partner or work in a group. You will be able to practise new
skills such as drawing force diagrams, completing a key and using models. As you practise
these new skills, you can check how you are doing and also challenge yourself to do better.
You will be able to reflect on how well you have worked and what you could do differently
next time.
We use science in our lives every day. You will see how science
knowledge is important when we discuss issues such as
pollution and how we must look after our air and water.
We hope you enjoy thinking and working like a scientist.
