Transcript of The Baking Soda and Vinegar Experiment!

By: Jonathan Beecham and Austin Kent The Baking Soda and Vinegar Experiment! A description of the Experiment Purpose: We are trying to figure out the effects of different ratios of vinegar on a set amount of baking soda (1 teaspoon). We are measuring the violence of the reaction for the sample of baking soda taken from the population through height in centimeters. The population is defined by 20 individual experimental units (sample) which are being tested upon. For the interpretation of the data, we compared the data between groups. For example, lets say we compared the 15 mL of vinegar group with that of the 10 mL of each group. By doing this one can see that the heights of the reactions in the 15 mL group appeared to be generally higher.
Possible lurking variables would be temperature. The temperature and humidity may have had an effect on the reaction. Also, another possible variable could be inaccurate measurements of baking soda and vinegar. All of the measurements may not have been exact, causing slight change in the reactions as well. Analyzation of the Experiment Visual Aid! For this experiment, what we would have done differently would be to have done the entire experiment in a controlled environment. The location in which this experiment was in allowed for too many lurking variables. We could have used a balance beam to precisely measure out the baking soda and vinegar to become as exact as possible.
Anyways, the results showed us that a higher ratio of vinegar to baking soda is more convenient for a higher reaction. Comparing the heights between Group 1 with 20 mL and Group 3 with 5 mL, one can easily see that Group 1, with 20 mL held by far more violent reactions than Group 3, with 5 mL. These results are exactly what we expected! Conclusions The way the experiment was conducted: we put one teaspoon of baking soda into each cup, and then poured the specific amount of vinegar needed into each cup. We put a ruler right by the cup as the reaction was occurring. As the reaction hit its peak, we recorded its height, and that is how the results were retrieved. (For some of the reactions, pictures were also taken at their heights!) 20 15 10 5 As one can see, each amount of vinegar is proportional to the violence of the reaction... The more vinegar, the more reaction! THE END
