Scientific Method

• A systematic approach to inquiry.

1. Observation

   • Recognizing phenomena or problems.

2. Question

   • Formulating questions about the observations.

3. Hypothesis

   • Proposing educated guesses or explanations.

4. Experimentation

   • Conducting experiments to test hypotheses.

5. Analysis

   • Analyzing data collected from experiments.

6. Conclusion

   • Drawing conclusions based on analysis.

7. Communication

   • Sharing results with the scientific community.

Key Concepts

• Theory vs. Law

  • Theory: Well-tested explanation of phenomena (e.g., Theory of Evolution).
  • Law: Statement about observed phenomena, often expressed mathematically (e.g., Law of Gravity).

• Variables

  • Independent Variable: Manipulated in experiments.
  • Dependent Variable: Measured response to changes in the independent variable.

• Peer Review

  • Process of evaluation by experts in the field to ensure quality and credibility of research.

Importance of Science

• Enhances understanding of the universe.
• Drives technological and medical advancements.
• Informs policy-making and problem-solving (e.g., climate change, public health).

Notable Scientific Figures

• Isaac Newton: Laws of motion and universal gravitation.
• Albert Einstein: Theory of relativity.
• Charles Darwin: Theory of evolution by natural selection.
• Marie Curie: Research on radioactivity.

Current Trends in Science

• Interdisciplinary research (e.g., bioinformatics, environmental science).
• Increased focus on STEM education.
• Ethical considerations in scientific research (e.g., gene editing).

Science and Society

• Role in addressing global challenges (e.g., pandemics, climate change).
• Public understanding and acceptance of science influenced by culture and media.

Scientific Method

• A systematic approach to inquiry involving these steps:
  • Observation: Identifying a phenomenon or problem.
  • Question: Formulating questions regarding the observation.
  • Hypothesis: Proposing educated guesses or explanations.
  • Experimentation: Testing hypotheses with systematic experiments.
  • Analysis: Analyzing the data collected during experiments.
  • Conclusion: Drawing conclusions based on the analysis.
  • Communication: Sharing results with the scientific community.

Key Concepts

• Theory vs. Law:
  • Theory: A well-tested explanation of phenomena, supported by evidence (e.g., the Theory of Evolution).
  • Law: A statement describing observed phenomena, often mathematically expressed (e.g., the Law of Gravity).
• Variables:
  • Independent Variable: The factor manipulated in an experiment.
  • Dependent Variable: The response measured as a result of changes in the independent variable.
• Peer Review: The process where research is evaluated by experts in the field to ensure quality and credibility.

Importance of Science
