How to remember the 7 Steps of the Scientific Method

 

1. Problem – The “thing” that you want to know. The question you want to answer.

2. Research - Information about the problem. What is already known?

3. Hypothesis - Educated guess, or prediction of the outcome of the           experiment. This guess can be tested by performing an experiment. 

4. Experiment- Tests the hypothesis.

5.          Observations - Data you collect during the experiment.

6. Conclusions - Determine if the hypothesis is correct or not.

7. Communicate - Present your results in a talk or a paper.

Example of the Seven Steps

1. Problem:  Do mice grow larger if given Vitamin C?2. Research: Learn about mice, their diet and vitamin C.3. Hypothesis: If mice are given vitamin C then they will 

     grow larger4. Experiment: Two groups of mice – one gets vitamin C, 

        one does not5. Observation: Weigh mice after 2 weeks – both groups 

        are the same size6. Conclusion: Hypothesis is not correct (rejected)7. Communicate:  Present your results

Identify the variables

• Manipulated or Independent Variable (IV)?– Get Vitamin C or no Vitamin C

• Responding or Dependent Variable (DV)?– Weight of mice

• Control Group-treated “normally”– Mice with no Vitamin C

• Experimental Group (IV is changed for this group)– Mice with Vitamin C

• Constants (controlled variables)– Same mice (genetically identical), same food (except for Vitamin C), same weight scale, same cage conditions,  same time frame..

• Conclusion– Accept or Reject the Hypothesis
