The Effect of Different Levels of Caffeine on the Growth of Wisconsin Fast Plants

AJAS · 2018

Hailey Nicks

Overview

The purpose of this experiment was to study the effects of various concentrations of caffeine on the growth of Wisconsin Fast Plants. Five different caffeinated liquids were compared in the study, coffee, green tea, chai black tea, vanilla spice chai tea, and 5 Hour Energy. The effects of the five liquids were compared to those of the control group. The plants were set up to absorb a mixture of water and eight ounces of the respective caffeinated liquid, or in the case of the 5 Hour Energy, two ounces, and were left to grow for four weeks. The hypothesis was that the 5 Hour Energy will enhance the growth of the Wisconsin Fast Plants by the largest amount, due to the drink containing the highest levels of caffeine when compared to the other substances in use in the experiment. The results of the experiment supported neither the hypothesis nor the null hypothesis, as the coffee group showed the greatest growth, on average, out of all of the plants. 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.
