What is science? – Picture Encyclopedia Dictionary
Science is the search for truth and knowledge.
It holds the key to understanding life, the Universe…and almost everything!
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.
Everything you see is made up of microscopic atoms.
Scientists divide science into different areas.
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!
Life science studies the living world around us.
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!
We have learned how to send energy to where it is needed
Earth and space science
Earth is a dot in a vast Universe filled with planets and moons, stars and galaxies. As far as we know, 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.
The scientific study of volcanoes is called volcanology.
Our Universe is filled with atoms and elements, molecules, mixtures, and compounds. Materials science is the study of these things, how they behave, how we use them, and how they react with one another.
One branch of science studies how materials can change.
