Introduction to Science and Its Methods

Definition and Purpose of Science

• Science is the systematic study of the natural world.
• Aims to understand, explain, and predict natural phenomena.
• Utilizes observation, experimentation, and analysis.

Scientific Method

1. Observation: Identifying a problem or question.
2. Research: Gathering existing information.
3. Hypothesis: Formulating a testable prediction.
4. Experimentation: Conducting experiments to test the hypothesis.
5. Analysis: Interpreting data and results.
6. Conclusion: Making inferences based on data.
7. Communication: Sharing results with the scientific community.

Branches of Science

• Natural Sciences: Study of the natural world.
  • Physics: Study of matter and energy.
