Effects of pH and Water Temperature on the Growth of Duckweed

We conducted a 2-Factor Design Of Experiment (DOE) that took place over a 14 day period. We tested the effects of two different pH levels and two water temperatures on the growth of duckweed. The test was conducted in a controlled setting that simulated a natural environment. Various groups of duckweed plants were exposed to the factors in order to determine the effects of the variables. Our experiment revealed that the varied pH and water temperatures had little or no negative effects on plant growth. The results showed that the control group (pH of 7 and water temperature of 22 degrees Celsius) proved to have the greatest effect on plant growth. We also concluded that duckweed has the ability to reproduce in a number of environmental conditions.
