Its goal is to apply scientific knowledge.
Advances in technology lead to advances in science, and visa versa. They depend on one another.

3. Branches of Science
Science is divided into social science and natural science.
Natural science is generally divided into 3 branches:
Physical science
Earth and space science
Life science

4. Physical Science Chemistry and physics are physical sciences.
Chemistry is the study of the makeup, structure, properties, and reactions of matter.
Physics is the study of matter and energy and the interactions between the two through forces and motion.

5. Earth Science

6. Life science
The study of living things is known as biology, or life science.
Like other branches of science, there are many divisions within biology:
Can you name what is studied in Zoology? Botany? Ecology? Genetics?
