Transcript of Copy of Scientific Method

Scientific Method 1. 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?" 2. Research- Find out as much as you can. Look for information in books, on the internet, and by talking with teachers to get the most information you can before you start experimenting. 3. Hypothesis- After doing your research, try to predict the answer to the problem. Another term for hypothesis is 'educated guess'. This is usually stated like " If I...(do something) then...(this will occur)" It will have a cause and effect---try to use the phrase "if then"

An example would be, "If I grow grass seeds under green light bulbs, then they will grow faster than plants growing under red light bulbs." Three parts of the hypothesis:
Independent Variable:
This is the part of your experiment that you will test (vary) to answer your hypothesis. In the example earlier, the independent variable would be the different colors of the light bulbs.
Dependent Variable:
This is what occurs in response to the changing independent variable. In our example the Dependent Variable is how much the grass seeds grow.
Control:
The control should be the part of the experiment where you do not include the Independent Variable. In our example, grass seed that is growing under the white (uncolored) bulb would be your control. The control lets you compare your results in the experiment. 4. Experiment- The fun part! Design a test or procedure to find out if your hypothesis is correct. 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. You would also set up grass seeds under regular white light so that you can compare it with the others. 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. 5. Analysis- Record what happened during the experiment. Also known as 'data'.
This should be represented as a graph or table 6. Conclusion- Review the data and check to see if your hypothesis was correct. If the grass under the green light bulb grew faster, then you proved your hypothesis, if not, your hypothesis was wrong. It is not "bad" if your hypothesis was wrong, because you still discovered something! http://www.sciencebob.com/sciencefair/scientificmethod.php Look at the scientists!
