All other aspects of the environment must remain constant and controlled, except for the variable you are testing. Once the experiment is designed, it must be carefully tracked and recorded. Observations and measurements are made and recorded, using graphs, tables and charts. A conclusion is drawn regarding the truth of the original hypothesis, based on the data acquired. Results of important experiments are usually published in scientific journals and written reports, where experts can critique the results.
Scientists often critique the design of the experiment and repeat it themselves.
Occasionally an expert will verify the results of the experiment but disagree with the conclusion that is drawn. At any rate, this peer review within the community assures that the integrity of the scientific method endures. Today you will use the five steps of the scientific method to design your own Science Stumper report. Read through today's Science Stumper from the Web site before you begin.
