Abstract
The purpose of this experiment was to study the effects of various concentrations of caffeine, found in coffee, on the growth of Wisconsin Fast Plants. Three different volumes of coffee were compared in the study, being 10 oz, 6 oz, and 2 oz, and all of which were Community Coffee Ground Dark Roast. The effects of the three liquids were compared to those of the control group. The plants were set up to absorb a mixture of water and the three respective ounces of the liquid coffee (or simply just water in the case of the control group), and were left to grow for a total of 15 days. The hypothesis was that the greatest concentration of caffeine, contained in the 10 oz of coffee, will have the greatest effect, and will cause the greatest acceleration of plant growth. In addition, the null hypothesis was that the control group would cause the greatest acceleration of plant growth, since it contained no caffeine. The results of the experiment supported neither the hypothesis nor the null hypothesis, since the 6 ounce group showed the most mean plant growth by the end of the fifteen day experiment period. In conclusion, this experiment could prove to be beneficial for plant growth, and determining if different caffeine concentrations could possibly act as a sort of stimulant for botanical growth.
