good question for scientific inquiry is asked in a way that actually suggests how the question can be answered. A good question should be focused on how one variable affects another. The resources that are available will also limit your question. Also, for this lab test, remember that you only have one day to do the actual lab work. Make sure your question is answerable in one hour of work. Hypothesis: Your research question can now aid you in developing a good hypothesis to guide your research or experimental design. A good, working hypothesis helps the investigator limit his or her investigation to the effect of one variable at a time. This allows the results to be clearly interpreted. To develop a working hypothesis, you need to establish the variables that you are studying and make a prediction on how those variables interact. Forming a hypothesis is a two-step process. 1. Define your variables. Determine which variable will change as you manipulate another. Consider the following question. "Does the temperature of germinating seeds affect the rate of cellular respiration?" The temperature of the germinating seeds is the manipulated variable (independent variable) and the rate of respiration is the experimental, or changing, variable (dependent variable). 2. State the relationship between the two variables in an " If... then " format. If the manipulated variable effects the experimental variable in such and such a way, then the experimental variable should change in such and such a manner when the manipulated variable is changed.
