Five Room Temperature Jars

The experiment was carried out in a Trent University greenhouse for a 14-day period. Ten small glass jars were labelled according to their treatment type (warm or room temperature). Room temperature jars were categorized as 1.1,1.2,1.3,1.4, and 1.5, then the warm temperature jars were 2.1,2.2,2.3,2.4, and 2.5. Jars were filled with a 100ml of federalized water, and a mark at the 100ml was made as indication to ensure the correct amount of water was given if the jars needed to be topped up. With a Q-tip, 10 green Lemna leaves with growing roots were placed into each of the ten designated jars. The five room temperature jars were placed into a tank that ranged at an average temperature of 22℃, and the remaining five were put into a warm tank that had an average temperature of 30℃. Over the fourteen days, participants went every other day of the week to count and record the Lemna leaves; the data collection occurred only on the days of Monday, Wednesday, and
The data was first used to calculate the average Lemna leaf growth throughout each of the jars in the warm and room temperature treatments. The equation used to determine the average leaves of the jars in the two treatments was . The standard deviation was calculated from the ten jars of the two treatments by days with the equation . This information was used to create Figure 1.0. For Figure 2.0, the average growth rate of Lemna leaves per day was calculated using the equation of for each of the jars in the two treatments, and then averaged using the equation as it gave the average growth rate in the warm and room temperature conditions. The standard deviation was calculated with the average Lemna leaves per day data, and put into the standard deviation equation . This data was used to created Figure
