Data Analysis
Conclusion
Retest

10. Problem
A problem is a question based upon observations.

11. Observations
Find out as much Information about the problem as possible.

12. Hypothesis
A suggested solution to the problem.
If…Then…

13. Experiment A procedure to test the hypothesis.
Control – experiment without the variable
Variable – factor being tested

14. Record and Analyze Data
Do the results of the experiment verify our hypothesis?

15. Make a Conclusion
The answer to the hypothesis. Either a confirmation or modification is necessary.

16. Publish and Retest
In order to verify the results, experiments must be retested by other scientists.
