    Study Notes

    Scientific Method

    • Science is a systematic approach to understanding the natural world.
    • It involves observation, experimentation, and the formulation and testing of hypotheses.
    • The scientific method is a cyclical process.
    • Formulating testable questions about observed phenomena.
    • Developing hypotheses that can explain the phenomena.
    • Designing controlled experiments to test the hypotheses.
    • Collecting and analyzing data from experiments.
    • Drawing conclusions based on the data.
    • Communicating the results for peer review and further investigation.

    Branches of Science

    • Science is broadly categorized into several branches.
    • Natural Sciences study the natural world.
    • Physical Sciences deal with non-living matter.
      • Examples include: Physics, Chemistry, and Astronomy.
    • Life Sciences deal with living organisms.
      • Examples include: Biology, Zoology, Botany, and Ecology.
    • Earth Sciences deal with the Earth.
      • Examples include: Geology, Meteorology, and Oceanography.
    • Social Sciences study human society and behavior.
      • Examples include: Psychology, Sociology, and Economics.

    Scientific Principles

    • The universe is understandable.
    • Natural laws are uniform in space and time.
    • Scientific ideas are subject to change as new evidence emerges.
    • Science is a human endeavor, and is affected by human biases.
    • Scientific explanations are based on evidence.
    • Science cannot provide answers to all questions. Some questions are beyond the realm of science (e.g., questions of morality, ethics).

    Scientific Investigations

    • Observation is crucial in science.
    • Observation of phenomena can lead to questions and hypotheses.
    • A hypothesis is a testable explanation for a phenomenon.
    • A control group is used as a basis for comparison with the experimental group.
    • Variables are factors that can be changed during an experiment.
      • Independent variables are manipulated.
      • Dependent variables are measured as a result.
    • Controlled experiments help isolate the effects of specific variables.
    • Data are collected and analyzed to determine if the hypothesis is supported or refuted.
    • Data can be represented using tables, graphs, or charts.
    • Scientific reports describe and explain the results.

    Scientific Theories and Laws

    • A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
    • Theories are supported by a large body of evidence and are more comprehensive than hypotheses.
    • Scientific laws describe observed patterns in nature. Laws are concise statements that summarize observed regularities in natural phenomena. They are typically expressed as mathematical equations.
