The question you developed in Chapter 1 will help you stay focused as you do your background research. Now, by changing the question into a hypothesis statement, you accomplish several critical research design issues. In writing a hypothesis, you will 1. determine a specific variable to be tested, 2. determine how changes within the experiment will be measured or recorded, and 3. predict an outcome of what you think the results of the experiment will be. For instance, in the following planaria example, the question only asks “how” reproduction is affected by temperature and is not written in such a way that it could be answered in a single experiment.
