    Study Notes

    Scientific Method Steps

    • The correct order of some steps in the scientific method is: initial observation, question, hypothesis, prediction, test the prediction.
    • The key step that distinguishes the scientific method from non-scientific methodologies is making a testable prediction.
    • A good prediction directly follows from a hypothesis. If the hypothesis is true, then [prediction].

    Hypothesis, Prediction, and Testing

    • A hypothesis is a proposed explanation for an observation.
    • A prediction is a statement of what will happen if the hypothesis is true (e.g., "If I [action], then [result]").
    • Testing a hypothesis involves conducting experiments or observations to see if the prediction holds true.

    Hypothesis vs. Theory vs. Law

    • A hypothesis is a proposed explanation for an observation.
    • A theory is a set of ideas (conceptual model) that explains many observations, involving tested hypotheses.
    • A law is a simple statement explaining a phenomenon, often described mathematically, with no known exceptions.

    Evolution as a Scientific Concept

    • Evolution is a fact (observable change in life forms over time).
    • The theory of evolution by natural selection explains how evolution happens, providing testable predictions.

    Components of Scientific Method

    • Previous knowledge is vital in formulating hypotheses and tests.
    • Observation is the initial step, followed by developing a question.
    • Hypothesis generates testable predictions.
    • Prediction should logically follow from the hypothesis, allowing for its testing.
    • Testing involves experimentation or observation to examine the prediction.
    • Results (from the test) lead to acceptance, revision, or rejection of the hypothesis.

    Scientific Reasoning and Critical Thinking

    • Scientists should be skeptical (the "will to doubt") rather than eager to believe.
    • Science depends on verifiable data and statistical analysis.
    • It's necessary that assumptions in observation and data analysis are objectively assessed and not subjective. Instruments and quantifiable measurements help in this.
    • Theories, like hypotheses, are tested explanations supported by many observations. The strength of a scientific theory lies in its ability to explain a broad range of phenomena and generate testable predictions.
    • The scientific method is not always linear or straightforward; serendipity, mistakes, and prior knowledge play a significant role.
