    Study Notes

    Branches of Science

    • Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
    • It encompasses various disciplines focused on specific aspects of the natural world, including physics, chemistry, biology, and astronomy.
    • Many scientific disciplines are interconnected and share common principles and methodologies.

    Scientific Method

    • The scientific method is a systematic approach to research involving observation, hypothesis formation, experimentation, data analysis, and conclusion drawing.
    • Key steps generally include: observing a phenomenon, developing a testable hypothesis, designing and executing experiments to test the hypothesis, collecting and analyzing data from the experiments, interpreting results and forming conclusions, and communicating findings to the scientific community.
    • The scientific method is an iterative process; results can lead to new questions and further investigations.

    Types of Scientific Investigations

    • Observational studies involve systematically documenting and measuring phenomena without manipulating variables.
    • Experimental studies involve manipulating one or more variables to determine their effect on another.
    • Controlled experiments aim to isolate the effects of specific variables by maintaining other variables constant.
    • Qualitative research may involve descriptions of phenomena rather than numerical measurements.
    • Quantitative research often involves statistical analysis of numerical data.

    Scientific Theories and Laws

    • A scientific law describes a fundamental relationship or regularity in nature, often expressed as a mathematical equation (e.g., Newton's laws of motion, the law of conservation of energy).
    • A scientific theory is a well-substantiated explanation of some aspect of the natural world, supported by a large body of evidence from many investigations (e.g. theory of evolution by natural selection).
    • Theories are not fixed; they may be modified or replaced as new evidence emerges.

    Scientific Models

    • Models are simplified representations of complex systems or processes, used to visualize, understand, and predict phenomena.
    • Models can be physical, mathematical, or computational and are essential for exploring and testing scientific hypotheses.

    Scientific Measurement and Units

    • Accurate measurement is crucial in science.
    • Standardized units of measurement facilitate communication and reproducibility.
    • The International System of Units (SI) is the globally accepted system, including base units (meters, kilograms, seconds) and derived units.

    Scientific Communication

    • Sharing research findings is vital for scientific progress.
    • Scientists communicate their work through publications in peer-reviewed journals and presentations/conferences.
    • Open access publications and online repositories enhance accessibility and knowledge sharing.

    Ethics in Science

    • Scientific research must adhere to high ethical standards, including accurately recording and reporting data, respecting participants' rights and well-being, avoiding plagiarism and data fabrication.
    • Ethical reviews and guidelines are crucial for responsible scientific practice.
