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 - Same mice (genetically identical), same food (except for Vitamin C), same weight scale, same cage conditions, same time frame… • Conclusion - Accept or Refect the Hypothesis
