The Scientific Method is an organized way of figuring something out. There are usually six parts to it.
Purpose/Question - What do you want to learn? An example would be, "Which doorknob in the 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?"
Research - Find out as much as you can. Look for information in books, the internet, and by talking with teachers to get the most information you can before you start experimenting.
Hypothesis - After doing your research, try to predict the answer to the problem. A hypothesis often simplified as and 'educated guess'; however, it must be testable. A hypothesis is usually stated an "If.... then ....." statment. " If I...(do something) then...(this will occur)"
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."
Experiment - The fun part! Design a test or procedure to find out if your hypothesis is correct.
Analysis - Record what happened during the experiment. Also known as 'data'.
Conclusion - Review the data and check to see if your hypothesis was correct. If your hypothesis was wrong it is not "bad", because you still discovered something!
A few other terms you may need to know:
This is the part of your experiment that you will test (vary) to answer your hypothesis. The "cause", the "if" part of and "If......then......." statement.
This is what occurs in response to the changing independent variable. The "effect", the "then" part of an "If......then......" statement. .
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.
