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.
