Document Summary
General principle deduction prediction experiments revision observations induction general principle. #1 modern science seeks explanations for observed phenomena that rely solely on natural causes. #2 science progresses through the creation and testing of models of nature that explain the observations as simply as possible. #3 a scientific model must make testable predictions about natural phenomena that would force us to revise or abandon the model if the predictions do not agree with observations. The word theory has a different meaning in science than in everyday life. In science, a theory is not the same as a hypothesis, rather: Explain a wide variety of observations with a few simple principles and. Must be supported by a large, compelling body of evidence, and. Must not have failed any crucial test of its validity. Astronomy is a science focused on learning about how stars, planets, and other celestial objects work.
