The Scientific Method (S.M.) is an
organized way to answer questions about the world
around us
*FYI*
Although there are different versions of
the S.M., all versions begin the
same step…
1. Identify a Problem/Observation
2. Form a Hypothesis
3. Design & Perform an Experiment
4. Collect and Analyze Results (Data)
5. Draw a Conclusion
6. Make a Prediction
Steps of the Scientific Method
1.1. Problem/ObservationProblem/Observation: Identify a problem or make an observation that can be
solved through experimentation
WHY???
Do you remember the Do you remember the next step?next step?
Steps of the Scientific Method
2. Form a HypothesisForm a Hypothesis: Predict a possible answer to the problem or
question.
WHAT IS A HYPOTHESIS? An educated guess based on observations
and what you already know.
Example of a HypothesisIf
I copy my work from other people,
then
I may make a good assignment grade but my test grade will be low
because
I did not learn the material for myself.
Steps of the Scientific Method
3. ExperimentExperiment: Design and conduct an experiment.
Things to think about:
- What materials will I need?
- What will my procedures be?
- Will my results be measurable?
Steps of the Scientific Method
• Expected results have to be quantifiable (some number)
• Control group- does not receive treatment so it remains the same and provides a standard
• Experimental group- receives the treatment that you are trying to test:
– The conditions that are changing in an experiment are called variables
– Independent variable- condition being tested – Dependent variable- the change that is measured
Collect and Analyze the Collect and Analyze the Results/DataResults/Data:
• Modify the procedure if needed
• Confirm the results by retesting (= reliable)
• Include tables, graphs, and pictures
Steps of the Scientific Method
5. Draw a ConclusionDraw a Conclusion: Include a statement that accepts or rejects the hypothesis.
- This statement should be able to stand alone:
• Bad example: Plant A died without water.
• Good example: In our experiment, we found that plant A can only survive for 10 days without water before dying so our hypothesis was correct.
Steps of the Scientific Method
- By drawing a conclusion, you are sharing your results with others:
- Be able to present your research and answer questions about it
- Make recommendations for further study and possible improvements to the procedure
Steps of the Scientific Method
6. Make a PredictionMake a Prediction: Create other experiments/studies that can further explain or support
your findings
Think you can name all Think you can name all six steps in order?six steps in order?
