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

Steps of the Scientific Method
1. Problem/Question: Develop a question or problem that can
be solved through experimentation.
Do all bags of M&Ms contain the same number of M&Ms?

Steps of the Scientific Method
2. Observation/Research: Make observations and research
your topic of interest. What do you already know
about M&M’s?

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

How to word your Hypothesis
If _______________________(independent variable- what you are purposely changing), then __________________________ (predicted change in the dependent variable)

Steps of the Scientific Method
4. Experiment: Develop and follow a procedure that is
repeatable. Include a detailed materials list.
The outcome must be measurable (quantifiable).

Design A Good Experiment
• There should only be one variable in the experiment
Variable- a factor that is changed in an experiment • The rest of the experiment should be
Controls- factors that are kept constant (the same)

Steps of the Scientific Method
5. Collect and Analyze Results: The collection of observations
is called data. Confirm the results by retesting.
Include tables, graphs, and photographs.

Steps of the Scientific Method 6. Conclusion: Include a statement that accepts or
rejects the hypothesis. Make recommendations for
further study and possible improvements to the
procedure.

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