    Study Notes

    Branches of Science

    • Natural Sciences:
      • Study of natural phenomena and laws of nature
      • Includes biology, chemistry, physics, and earth sciences
    • Formal Sciences:
      • Focus on abstract structures and formal systems
      • Includes mathematics, logic, and computer science
    • Applied Sciences:
      • Practical application of scientific knowledge
      • Includes engineering, medicine, and technology

    Scientific Method

    1. Observation: Identify a problem or phenomenon
    2. Hypothesis: Formulate a testable explanation
    3. Prediction: Make a forecast based on the hypothesis
    4. Experimentation: Design and conduct experiments to test the hypothesis
    5. Analysis: Interpret data and draw conclusions
    6. Conclusion: Accept, reject, or modify the hypothesis

    Key Scientific Concepts

    • Theories: Well-substantiated explanations for a set of phenomena
    • Hypotheses: Testable predictions based on a theory
    • Laws: Descriptive statements of natural phenomena
    • Variables: Factors that can be changed or controlled in an experiment
    • Control Groups: Groups used as a standard of comparison in an experiment
    • Empiricism: The idea that knowledge comes from sense experience and observation

    Branches of Science

    • Natural Sciences study natural phenomena and laws of nature, including biology, chemistry, physics, and earth sciences.
    • Formal Sciences focus on abstract structures and formal systems, including mathematics, logic, and computer science.
    • Applied Sciences involve the practical application of scientific knowledge, including engineering, medicine, and technology.

    Scientific Method

    • Observation: Identify a problem or phenomenon, which is the first step in the scientific method.
    • Hypothesis: Formulate a testable explanation, which is a prediction based on limited data.
    • Prediction: Make a forecast based on the hypothesis, which is a specific and measurable outcome.
    • Experimentation: Design and conduct experiments to test the hypothesis, which involves data collection and analysis.
    • Analysis: Interpret data and draw conclusions, which involves identifying patterns and trends.
    • Conclusion: Accept, reject, or modify the hypothesis, which is the final step in the scientific method.

    Key Scientific Concepts

    • Theories: Well-substantiated explanations for a set of phenomena, which are based on a large amount of data and evidence.
    • Hypotheses: Testable predictions based on a theory, which are used to make predictions and forecast outcomes.
    • Laws: Descriptive statements of natural phenomena, which are based on consistent patterns and observations.
    • Variables: Factors that can be changed or controlled in an experiment, which are used to test hypotheses and identify cause-and-effect relationships.
    • Control Groups: Groups used as a standard of comparison in an experiment, which are used to provide a baseline for measuring the effect of a variable.
    • Empiricism: The idea that knowledge comes from sense experience and observation, which is a fundamental principle of scientific inquiry.
