Book Preface

Science is the search for truth and knowledge. Scientists suggest explanations of why things are as they are, and then they test those explanations, using experiments. Some of what science discovers can be applied to our everyday lives.

Life science

How do living things survive and grow, where do they live, what do they eat, and how do their bodies work? Life science seeks to answer such questions about the living world, from microscopic bacteria to plants and animals – including you!

From atoms to space Scientists study a huge variety of things – from the tiniest atoms that make up everything around us to the mysteries of space.

Physical science

This science looks at energy and forces. There are different types of energy, including light, heat, and sound. Forces are the things that hold everything in place in our world. Without the force of gravity, for example, you would fly off into space!

Earth and space science The Earth is a dot in a vast Universe filled with planets and moons, stars and galaxies. As far as we know, the Earth is special because it is the only place that supports life. Earth and space science is the study of the structure of our planet – and everything that exists beyond it.

Materials science

Our Universe is filled with atoms and molecules, which make up elements, compounds, and mixtures. Materials science is the study of these things, how they behave, how we use them, and how they react with one All about change

People always want to make life better, and that’s what puts us on the road to scientific discovery. Whether it’s finding cures or sending rockets into space, science drives us onwards, changing the world we live in.another.
