Simple Definition:
Science [The study of the world around us]

Science is the study of the world around us [everything we can see, touch, feel, and measure]. Scientists use methods [ways of doing things] like observation [looking carefully], experimentation [trying things out], and analysis [studying something closely] to understand how things work. They use their findings [what they discover] to make predictions [guesses about what will happen] and create theories [ideas that explain something] about the natural world [everything that is not made by humans].

Science helps us understand everything from the tiniest particles [tiny pieces] that make up matter [everything that has mass and takes up space] to the vastness [huge size] of the universe [all of space, time, matter, and energy]. It helps us solve problems [figure out how to fix things] and make discoveries [finding out new things] that improve our lives and the world we live in.

Some examples of science at work:

Biology is a branch of science that studies living things like plants and animals. Biologists observe and study their behavior, anatomy, and genetics to better understand how they function and evolve.

Physics is another branch of science that focuses on the study of matter, energy, and how they interact. Physicists use experiments to test theories about the natural world, such as how gravity works or how atoms behave.

Medical science is an important field that uses science to help improve people’s health. Doctors and researchers use scientific methods to study diseases and develop new treatments to help people feel better.

Environmental science is the study of the natural world and how it is affected by human activity. Scientists in this field work to understand how we impact the planet and how we can reduce our negative impact.

Astronomy is the study of space and the objects in it. Astronomers use telescopes and other tools to study planets, stars, galaxies, and other celestial bodies to better understand the universe.

Very Simple Definition:

Science is learning about the world. Scientists use ways of looking carefully, trying things out, and studying things closely to figure out how things work. They make guesses and ideas about everything around us, from tiny pieces to everything in space. Science helps us solve problems and find new things that make our lives better.

Here are some simpler examples of science at work:

Biology: Scientists study animals and plants to learn more about them. They look at how they behave and what they are made of.

Physics: Scientists study how things move and what they are made of. They test ideas about the world to learn more about it.

Medical Science: Scientists study how the body works and how to help people feel better. They find new ways to treat diseases and help people stay healthy.

Environmental Science: Scientists study how people affect the planet and how to make things better. They look at things like air pollution and climate change.

Astronomy: Scientists study space and the things in it. They use telescopes to look at stars, planets, and galaxies to learn more about the universe.
