![]() ![]() The control should be the part of the experiment where you do not include the Independent Variable. In our example the Dependent Variable is how much the grass seeds grow. This is what occurs in response to the changing independent variable. In the example above, the independent variable would be the different colors of the light bulbs. This is the part of your experiment that you will test (vary) to answer your hypothesis. It is not “bad” if your hypothesis was wrong, because you still discovered something! If the grass under the green light bulb grew faster, then you proved your hypothesis, if not, your hypothesis was wrong. Conclusion – Review the data and check to see if your hypothesis was correct.Analysis – Record what happened during the experiment. ![]() If you are doing this for a science fair, you will probably have to write down exactly what you did for your experiment step by step. You would also set up grass seeds under regular white light so that you can compare it with the others. In our example, you would set up grass seeds under a green light bulb and seeds under a red light and observe each for a couple of weeks. Experiment – The fun part! Design a test or procedure to find out if your hypothesis is correct.This is usually stated like ” If I…(do something) then…(this will occur)”Īn example would be, “If I grow grass seeds under green light bulbs, then they will grow faster than plants growing under red light bulbs.” Another term for hypothesis is ‘educated guess’. Hypothesis – After doing your research, try to predict the answer to the problem.Look for information in books, on the internet, and by talking with teachers to get the most information you can before you start experimenting. Research – Find out as much as you can.Purpose/Question – What do you want to learn? An example would be, “What doorknob in school has the most germs ?” or “Do girls have faster reflexes than boys?” or “Does the color of a light bulb affect the growth of grass seeds?”.The Scientific Method is an organized way that helps scientists (or anyone!) answer a question or begin to solve a problem. ![]()
