Define the scientific method and list its key steps.

  • Scientific Method: The scientific method is a systematic approach to gaining knowledge through observation, experimentation, and analysis. It aims to answer questions about the natural world in an objective and repeatable way.
  • Key Steps:
    1. Observation: Identify and observe a phenomenon.
    2. Question: Formulate a research question based on the observation.
    3. Hypothesis: Develop a testable explanation or prediction.
    4. Experiment: Conduct experiments to test the hypothesis.
    5. Analysis: Analyze the data to determine if the hypothesis is supported.
    6. Conclusion: Draw conclusions based on the experiment’s results.
    7. Report: Share results with the scientific community for verification.
