What is Science?

Hint: To begin with, science enhances our understanding of the world around us. Everything we know about the cosmos is the result of scientific investigation and experiment, from how trees reproduce to what an atom is composed of. Science is a vital part of our everyday lives. Everyone should have a basic understanding of science since it makes our lives easier and expands our minds in many ways. Science does not change over time because it is entirely based on facts and experiments.

Complete answer:
Science is described as a body of knowledge about the physical world and the things that occur within it. It is an objective observation that explains nature's fundamental laws. Another approach to define science is that it is the knowledge gained through experience.
There are four major disciplines of science, each of which is divided into multiple subjects that cover various topics such as chemistry, physics, arithmetic, and astronomy. Mathematics and logic, biological science, physical science, and social science are the four primary science branches.
Chemistry. The study of matter's qualities and how it changes.
Physics. The study of matter and energy, as well as their interactions through forces and motion.
Geology. The study of the earth's structure.
Astronomy. The exploration of the universe.
Biology. The study of living things.
Science is used in various fields such as agriculture, medicine, transportation, communication, construction etc.
Thus, science has vast use in all fields of human lives.

Note:
Science is one of the most ancient and essential academic fields, and it encompasses a vast range of topics. It's also a key component in the abbreviation STEM, which stands for science, technology, engineering, and mathematics.
