    Study Notes

    Introduction to Science

    • Science is a systematic and organized body of knowledge explaining the natural world through observation, experimentation, and testable theories.
    • It relies on empirical evidence, based on verifiable observations and measurements.
    • Scientific knowledge evolves, refining and updating with new data and insights.
    • Various branches exist, including physics, chemistry, biology, and Earth science.

    Scientific Method

    • The scientific method is a systematic approach to scientific inquiry, helping researchers gather knowledge and test hypotheses.
    • Steps typically include:
      • Observation: Noting a phenomenon needing explanation.
      • Question: Asking a specific question about the observation.
      • Hypothesis: A testable explanation (often "if...then..." format).
      • Prediction: A measurable prediction following from the hypothesis.
      • Experiment: Controlled testing of the hypothesis and prediction.
      • Data Analysis: Evaluating data to see if it supports or refutes the hypothesis.
      • Conclusion: Drawing conclusions based on data, recognizing results might support or reject the hypothesis, with both providing valuable information.

    Key Concepts in Science

    • Theory: A well-substantiated explanation based on a large body of evidence, incorporating facts, laws, inferences, and tested hypotheses. It's not a mere guess.
    • Law: A descriptive statement or equation predicting specific natural phenomena under given conditions. It describes what happens, not necessarily why.
    • Variables:
      • Independent variables are manipulated to see their effect.
      • Dependent variables change in response to the independent variable.
      • Controlled variables are kept constant to isolate the effect of the independent variable.
    • Models: Representations or analogies to illustrate complex phenomena, like diagrams of atomic structures.

    Scientific Attitudes

    • Curiosity: Drives the scientific quest, generating research questions and experiments.
    • Skepticism: Questioning claims and critically evaluating evidence is essential to avoid bias.
    • Objectivity: Avoiding personal opinions and biases in observation and data analysis.
    • Open-mindedness: Accepting new information, potentially contradicting existing ideas.

    Scientific Communication

    • Sharing findings through publications and conferences advances science.
    • Peer review ensures research validity and reliability.
    • Clear, accurate communication, including proper data presentation, is crucial.
    • Precise language and standardized methods enhance reliable results.
