Science helps us to answer questions. If we look for evidence and do experimentsto test new ideas, we can understand how and why things work. We divide science into three main areas: chemistry, biology, and physical
Living things
Biology is the study of living thing and their surroundings. It includes how humans, plants, and animals behave, grow, and adapt to changes in their environment.
Movement and forces
Physics is the study of gravity, magnets, light, electricity, waves, sound, heat, energy, forces, and how objects move.
Why is science useful ?
Expanding knowledge
When scientists investigate ideas and do experiments, they discover new information about the world around them. People can use that information to come up with more new ideas.
Solving problems
When we know more about how things work, we can invent new things to help us. For example, if we understand motion we can design faster cars.
True or false ?
1. Chemistry is the study of living things.
2. New discoveries can be unpopular when scientists first make them.
