    Study Notes

    Definition of Science

    • Systematic enterprise that builds and organizes knowledge.
    • Involves observation, experimentation, and analysis.

    Branches of Science

    1. Natural Sciences

      • Focus on the physical world.
      • Subdivisions:
        • Physics: Study of matter and energy.
        • Chemistry: Study of substances and their interactions.
        • Biology: Study of living organisms.

    2. Formal Sciences

      • Study of abstract concepts.
      • Includes:
        • Mathematics: Numbers, quantities, shapes.
        • Logic: Principles of valid reasoning.
        • Statistics: Collection and analysis of data.

    3. Social Sciences

      • Study of human behavior and societies.
      • Subdivisions:
        • Psychology: Study of mind and behavior.
        • Sociology: Study of social behavior and society.
        • Economics: Study of production, distribution, and consumption.

    Scientific Method

    1. Observation: Gathering data through senses.
    2. Question: Formulating a question based on observations.
    3. Hypothesis: Proposing a testable explanation.
    4. Experimentation: Conducting tests to validate or refute the hypothesis.
    5. Analysis: Interpreting data and results.
    6. Conclusion: Drawing results based on analysis and evaluating the hypothesis.

    Importance of Science

    • Advances knowledge and technology.
    • Addresses global challenges (e.g., health, environment).
    • Informs policy and decision-making.

    Key Concepts

    • Theory: A well-substantiated explanation of some aspect of the natural world.
    • Law: A statement based on repeated experimental observations.
    • Peer Review: Evaluation of research by experts in the field.

    Ethical Considerations

    • Integrity in research and reporting.
    • Respect for human and animal subjects.
    • Environmental responsibility.

    Definition of Science

    • Science is a systematic enterprise dedicated to building and organizing knowledge.
    • It relies on observation, experimentation, and analysis to understand phenomena.

    Branches of Science

    • Natural Sciences: Concentrate on the physical world. Key subdivisions include:

      • Physics: Investigates matter, energy, and their interactions.
      • Chemistry: Explores substances, their properties, and chemical reactions.
      • Biology: Examines living organisms, their structures, functions, and interactions.

    • Formal Sciences: Focus on abstract concepts and include:

      • Mathematics: Deals with numbers, quantities, shapes, and their relationships.
      • Logic: Studies principles of valid reasoning and argumentation.
      • Statistics: Involves the collection and analysis of quantitative data.

    • Social Sciences: Analyze human behavior and societal structures. Subdivisions include:

      • Psychology: Focuses on mental processes and behavior.
      • Sociology: Investigates social behavior, institutions, and relationships within society.
      • Economics: Studies the production, distribution, and consumption of goods and services.

    Scientific Method

    • Observation: Involves collecting data using the senses.
    • Question: Deriving a precise question from observations.
    • Hypothesis: Formulating a testable and falsifiable explanation for the observed phenomena.
    • Experimentation: Implementing tests to assess the validity of the hypothesis.
    • Analysis: Interpreting collected data to draw insights.
    • Conclusion: Summarizing findings and determining the truth or falsity of the hypothesis based on analysis.

    Importance of Science

    • Enhances understanding and drives technological advancements.
    • Provides insights to tackle global challenges like health crises and environmental issues.
    • Aids in informing policy-making and socio-political decision processes.

    Key Concepts

    • Theory: A well-substantiated explanation that integrates numerous observations and experiments about aspects of the natural world.
    • Law: A statement that describes consistent observations in nature based on repeated experimental results.
    • Peer Review: A critical evaluation process where experts assess research quality, validity, and relevance prior to publication.

    Ethical Considerations

    • Ensures integrity and honesty in research practices and reporting outcomes.
    • Emphasizes the importance of respecting human and animal subjects involved in research.
    • Stresses the need for environmental stewardship and responsible research conduct.
