Questions and Answers

What is the primary distinction between scientific theories and scientific laws?

  • Laws are well-substantiated explanations, while theories summarize observed patterns.
  • Theories provide predictions while laws describe observations. (correct)
  • Theories are based on facts, while laws are based on hypotheses.
  • Theories can change with new evidence, while laws remain constant.

    • What best describes the role of scientific models in research?

  • Models can only be physical representations of processes.
  • Models assist in visualizing complex systems and making predictions. (correct)
  • Models replace the need for experiments in scientific inquiry.
  • Models are used primarily for data collection and analysis.

    • Which of the following accurately characterizes the process of scientific inquiry?

  • Scientific inquiry does not necessitate collaboration among scientists.
  • Scientific inquiry is iterative and often requires adjustments based on findings. (correct)
  • Scientific inquiry is solely dependent on quantitative data.
  • Scientific inquiry is linear and leads to definitive conclusions every time.

    Study Notes

    Scientific Method

    • Science is a systematic approach to understanding the natural world.
    • It relies on observation, experimentation, and analysis to develop and test theories.
    • The scientific method is a framework for conducting scientific inquiry. It involves formulating a hypothesis, designing experiments to test the hypothesis, collecting and analyzing data, and drawing conclusions about the validity of the hypothesis.
    • Scientific theories are well-substantiated explanations of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
    • A scientific law describes an observed pattern in nature without attempting to explain it.
    • Scientific theories and laws are constantly being refined or replaced as new evidence emerges.

    Branches of Science

    • Several branches of science exist.
    • Physical sciences study non-living matter. Examples include physics, chemistry, and astronomy.
    • Life sciences study living organisms. Examples include biology, botany, and zoology.
    • Earth sciences study the Earth, its processes, and its resources. Examples include geology, meteorology, and oceanography.
    • Social sciences study human society and behavior. Examples include psychology, sociology, and economics.

    Scientific Measurements

    • Accuracy refers to how close a measurement is to the true value.
    • Precision refers to how close multiple measurements are to each other.
    • Significant figures indicate the precision of a measurement.
    • Units of measurement are standardized to ensure consistency and clarity in scientific communication.

    Scientific Models

    • Models are simplified representations of complex systems or processes.
    • They can be physical, mathematical, or conceptual.
    • Models help scientists visualize and understand phenomena that may be difficult or impossible to observe directly.
    • Models are used to make predictions and test hypotheses.

    Scientific Inquiry

    • Scientific inquiry involves asking questions, gathering data, drawing conclusions, and communicating results.
    • This process is typically iterative, with revisions and refinements based on new findings.
    • Critical thinking and skepticism are essential components of scientific inquiry.
    • Scientific progress relies on collaboration and open communication among scientists.

    Scientific Ethics

    • Conducting research with integrity and honesty is crucial.
    • Avoiding bias and ensuring objectivity in data collection and analysis is vital.
    • Maintaining confidentiality and respecting the rights of participants in research is imperative, particularly in human subjects research.
    • Scientists must comply with ethical guidelines and regulations to respect applicable laws and avoid harm.
