1. The steps for thescientific method are listed in Chapter 1. List and explain each of the steps in the scientific method in the context of the following situation. You do not have to resolve the question; just explain the steps for resolving the question:

It is well known that objects expand when heated. An iron plate will get slightly larger when put in a hot oven. Suppose an iron plate has a hole cut in the center. Will the hole get larger or smaller when the plate is heated and expansion occurs?

a Scientific Methods There is no our scientic method. But there are common Features in the way scientists do their work, dating back to the Italian physicist Galileo Galilei (15641642) and the English philosopher Francis Bacon (15611626). They broke free from the methods of the Greeks, who worked \"upward or downwa rd,\" depending on the circumstances. reaching conclusions about the physical world by reasoning from arbitrary assumptions (axioms). The modern scientist works \"upward,\" first examining the way the world actually works and then building a structure to explain the findings. Although no cookbook description of the scientific method is really adequate, some or all of the Following steps are likely to be found in the way most scientists carry out their work. 1. Recognize a question or a puzzlesuch as an unexplained faet. 2. Make an educated guessa hypothesis~that might resolve the puzzle. 3. Predict consequences of the hypothesis. 4. Perform experiments or make calculations to test the predicrions. 5. Formulate the simplest general rule that organizes the three main ingredients: hypothesis, predicred effects, and experimental findings. Although these steps are appealing, much progress in science has come from trial and error, experimentation without hypotheses, or just plain accidental dis- covery by a well-prepared mind. The success of science rests more on an attitude common to scientists than on a particular method. This scientic attitude is one ofinquiry, integrity, and humilitywthat is, a willingness to admit error. "r't F - -f'- a - 1
