Scientific Method
February 10, 2013

3. Objectives
1. Recognize the Steps of the Scientific
Method
2. Understand the terminology that is
involved
3. Use an example problem to work
through each of the Steps

4. The Scientific
Method involves a
series of steps that
are used to
investigate a
natural
occurrence.

5. Problem/Question
Observation/Research
Formulate a Hypothesis
Experiment
Collect and Analyze Results
Conclusion
Communicate the Results

6. Steps of the
Scientific Method
1. Problem/Question:
Develop a question or problem that
can be solved through
experimentation.

7. Steps of the
Scientific Method
2. Observation/Research:
Make observations and research your
topic of interest.

8. Steps of the
Scientific Method
3. Formulate a Hypothesis:
Predict a possible answer to the
problem or question.
Example: If soil temperatures rise, then
plant growth will increase.

9. Steps of the
Scientific Method
4. Experiment:
Develop and follow a procedure.
 Include a detailed materials list.
 The outcome must be measurable
(quantifiable).
 Include tables, graphs, and
photographs.

10. Steps of the
Scientific Method
5. Collect and Analyze Results:
Modify the procedure if needed.
Confirm the results by retesting.
Make recommendations for further
study and possible improvements to
the procedure.

11. Steps of the
Scientific Method
6. Conclusion:
Include a statement that accepts or
rejects the hypothesis.

12. Steps of the
Scientific Method
7. Communicate the Results:
Be prepared to present the project to
an audience.
 Expect questions from the audience.

13. Variables
Independent Dependent
 a factor that’s  the factor that
varied by the may change as a
experimenter. result of changes
made in the
independent
variable.

14. Control Group
 standard of comparison.
 may be a “no treatment" or an
“experimenter selected” group.
 exposed to the same conditions as the
experimental group
 except for the variable being tested.

15. Constants
 factors that the
experimenter attempts
to keep the same.

16.  Modern Marvels Measurement
