Baking Soda and Vinegar: A Statistical Approach to a Chemical Reaction

Does the ratio of ingredients make a difference? Groups perform an experiment with baking soda and vinegar. They vary the ratio of the components each time and take measurements of the amount of gas produced. Using the combined class data, teams compare the results of the different ratios with the appropriate measures of center and variation.

Instructional Ideas

  • Conduct a mini-review on how to determine which measure of center or variation to use based upon the shape of the data
Classroom Considerations

  • The class should know how to find measures of center and variation
  • Gather the materials including safety glasses for each group
Pros

  • Provides a list of materials needed to conduct the experiment
  • Includes links to tutorials on using GeoGebra to create the plots
Cons

  • None
