  1. Exploration and Discovery: Where Ideas Come From • What scientific attitudes help generate new ideas? • 1) Scientific Attitudes • 2) Practical Problems • 3) The Role of Technology • Communicating Results: Reviewing and Sharing Ideas • Why is peer review important? • Peer Review • Sharing Knowledge and New Ideas • Scientific Theories • What is a scientific theory? • Science and Society • What is the relationship between science and society? • 1) Science, Ethics, and Morality • 2) Avoiding Bias • 3) Understanding and Using Science The Science of Biology 1.2 Science in Context----Outline

  2. Scientific Theories • What is a scientific theory? • In science, • theory = a well-tested explanation that unifies a broad range of observations and hypotheses and that enables scientists to make accurate predictions about new situations. • In society, • theory = a hunch, a guess.

  3. Scientific Theories • Evidence from many scientific studies may support several related hypotheses in a way that inspires researchers to propose a scientific theory that ties those hypotheses together. • In science: • Theory applies to a well-tested explanation that unifies a broad range of observations and hypotheses. • Enables scientists to make accurate predictions about new situations. • A useful theory that has been thoroughly tested and supported by many lines of evidence may become the dominant view among the majority of scientists. • But, no theory is considered absolute truth. • Science is always changing; as new evidence is uncovered, a theory may be revised or replaced by a more useful explanation.

  4. Scientific Theories vs. Laws • Theory applies to a well-tested explanation that unifies a broad range of observations and hypotheses. • Is the explanation • More dynamic, complex • Contain many more ideas and hypotheses • Ex: • Law = A concise description of how the natural world functions. = a specific descriptions of how some aspect of the natural world is expected to behave in a certain situation • Is the how come • Ex: • THEORIES DO NOT BECOME LAWS OVER TIME
