Scientific Method What is it? Science does not define truth, but rather it defines a way of thought. It is a process in which experiments are used to answer questions. The simple version looks something like this: Observe some aspect of the universe. Make a guess about what would explain what you have observed; this is called a hypothesis. Use the hypothesis to make predictions. Test those predictions by experiments or further observations and modify the hypothesis to better explain your results. Repeat steps 3 and 4 until there are no differences between your guess of what happened at the end of the experiment and/or observation to test it. When the same results are obtained over and over, the hypothesis becomes a theory and provides a foundational set of rules. Give me an example! Have you ever noticed that the refrigerator light only comes on when you open the door? If you have wondered why, then you can apply the scientific method! First make a guess how the light comes on and goes off. Was it refrigerator elves? A magnetic field? Once you have an idea, try to prove your ideas with some experiments and research. Repeat the experiment at least three times. If you and other people do the same experiment and get the same results, you may have a theory! Copyright ©2010, PCS Edventures, Inc. All Rights Reserved.
