How to remember the 7 Steps of the Scientific Method “People Really Hate Elephants On Compact Cars. ” 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? Hypothesis - Educated guess, or prediction of the outcome of the 3. experiment. This guess can be tested by performing an experiment. 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. 4.

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 larger 4. Experiment: Two groups of mice – one gets vitamin C, one does not 5. Observation: Weigh mice after 2 weeks – both groups are the same size 6. 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
