Scientific Method



1.      Question: What do I want to know? What do I want to study?

2.      Hypothesis: Educated guess or prediction based on the question I want studied.

3.      Experiment: What a scientist will do to prove his/her hypothesis to be true or false

4.      Test: Finding an average of the data to help analyze if the hypothesis is correct or incorrect.

5.      Results: Analysis of the data. Is the hypothesis correct or incorrect? How close is the data?

6.      Conclusion: If the hypothesis is correct you may keep the hypothesis. If the hypothesis is wrong, you may do one of two things:

a.      Reject hypothesis and make new one.

b.     Redo experiment to see if you get the same results


7.      Materials: What materials were used in the experiment?

8.      Outside influences: What things could of influenced the experiment to cause it to come out like it did?



If a hypothesis always comes up with the same result, even if other scientists conduct the experiment, we will call that hypothesis a theory. If the theory is accepted by almost all scientists and is almost impossible to prove wrong, we call that a Law.


Control: The control are the parts of an experiment that are kept the same to make sure that outside influences do not affect an experiment.


Independent variables: Independent variables are the parts of the experiment that we change and compare to see if there are any differences.


Dependent variables: Dependent variables are the parts of the experiment that are the results of how we used the independent variables.
