     • Mathematics: Study of numbers, quantities, and shapes.
     • Statistics: Study of data collection, analysis, interpretation.
     • Computer Science: Study of computation and information systems.
3. Social Sciences
   • Study of human behavior and societies.
   • Includes:
     • Psychology: Study of mind and behavior.
     • Sociology: Study of social behavior and society.
     • Economics: Study of production, distribution, and consumption of goods.

Scientific Method

• A systematic approach to inquiry involving:
  1. Observation: Gathering information about a phenomenon.
  2. Hypothesis: Formulating a testable explanation.
  3. Experimentation: Conducting tests to validate or refute the hypothesis.
  4. Analysis: Interpreting data collected during experiments.
  5. Conclusion: Drawing inferences based on the analysis.
  6. Communication: Sharing results with the scientific community.

Importance of Science

• Drives technological advancements and innovation.
• Informs policy and decision-making.
• Enhances understanding of health, environment, and society.
• Encourages critical thinking and problem-solving skills.

Key Concepts in Science

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describes some aspect of the universe.
• Hypothesis: A proposed explanation for a phenomenon, subject to testing.
• Experiment: A controlled procedure to test hypotheses.

Ethical Considerations

• Importance of ethics in scientific research.
• Issues include:
  • Integrity: Honesty in reporting data and results.
  • Respect for subjects: Ensuring the welfare of human and animal participants.
  • Environmental responsibility: Considering the impact of research on ecosystems.
