B. The Scientific Method: the scientific method is a step-wise process for experimentation that is used to answer questions and explore observations. Hypothesis: any proposed explanation for an observed phenomenon. What scientists do is to propose and then evaluate hypotheses by experimentation or further observation. Theory: a hypothesis or set of hypotheses that is consistent with virtually all of the available evidence. Sometimes referred to as a “law of nature”. 1 observe something 4 make a prediction 5 experiment/test 3 formulate a hypothesis 2 ask a question 6 revise hypothesis An acceptable alternative to deductive , hypothesis-driven (“experimental”) science: inductive reasoning (generalize from a large body of consistent observations) e.g., Cell Theory Monday, June 13, 2011

Why doesn’t this %^ $#!& fashlight work??!?!?!? Fig. 1.24 (1.25, 7th) 2. Falsi±ability: this means that there must be some experiment or possible discovery that could prove the hypothesis/theory untrue. Monday, June 13, 2011
