Science Quiz: Definitions and Branches

Definition of Science

• Systematic study of the natural world.
• Involves observation, experimentation, and analysis.

Branches of Science

1. Natural Sciences

   • Focus on the physical world and its phenomena.
   • Includes physics, chemistry, biology, earth science, and astronomy.

2. Formal Sciences

   • Study systems based on abstract concepts and logical reasoning.
   • Includes mathematics, statistics, and computer science.

3. Social Sciences

   • Study human behavior and societies.
   • Includes psychology, sociology, anthropology, and economics.

4. Applied Sciences

   • Use scientific knowledge for practical applications.
   • Includes engineering, medicine, and environmental science.

Scientific Method

1. Observation

   • Identify a phenomenon or problem.

2. Hypothesis

   • Formulate a testable explanation or prediction.

3. Experimentation

   • Conduct experiments to test the hypothesis.
   • Use control and experimental groups.

4. Data Collection

   • Gather quantitative or qualitative data during experiments.

5. Analysis

   • Analyze results to determine if they support or refute the hypothesis.

6. Conclusion

   • Draw conclusions based on the analysis.
   • Can lead to further hypotheses or experiments.

7. Peer Review

   • Submit findings for evaluation by other scientists before publication.

Importance of Science

• Enhances understanding of the universe.
• Drives technological innovation.
• Informs public policy and decision-making.
• Addresses global challenges (e.g., climate change, health crises).

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement that describes an observable phenomenon, often expressed mathematically.
• Variable: Any factor that can affect the outcome of an experiment (independent, dependent, controlled).

Ethical Considerations

• Integrity in research and reporting.
• Responsible use of technology and scientific knowledge.
• Impact of scientific advancements on society and the environment.

Careers in Science
