What is Science?
Science is an organized body of knowledge that is based on the systematic study of the natural world. It relies on observation, experimentation, and empirical evidence to form theories and laws that explain various phenomena. The scientific method is a critical component of science, involving the following steps:
- Observation
- Question
- Hypothesis
- Experimentation
- Analysis
- Conclusion
These steps help scientists to systematically explore questions about the universe and validate their findings through repeatable experiments.
