Methods:
To start this experiment place four seeds in four separate petri dishes with a damp paper towel. Once the seed germinates and the plant has begun to sprout, move the seeds to four separate pots, and add soil. Once the plants have begun to sprout take the measurement of each plant and record your data for day zero. Next, take three glass containers of greatly varying volumes (41,4185cm3, 2,250cm3, and 602cm3 were used). Before the plants are placed underneath these containers, give 15ml of water to each plant. The numbered pots will remain underneath these three containers for the next two weeks, untouched. The fourth pot will remain in open air, under no container. This is the only plant that will get watered every other day another …show more content…
The trendline shown is barely decreasing, which shows a negative correlation between the amount of carbon dioxide and and the percent of growth from the plants. However, it can be perceived that this trendline was negative for many other reason besides the limited amount of carbon dioxide. This proves that there were not enough constants in this experiment for reliable results; preventing the ability to draw conclusions from this …show more content…
The containers placed over the plants were not guaranteed to be air-tight, this means that the plants were exposed to unlimited amounts of carbon dioxide. With this being the case, the health of the plants and the overall growth of the plants was not based on the amount of carbon dioxide, but other abiotic factors. One of these factors would be the greenhouse effect. Since the plants were placed underneath containers, underneath heat lamps, the greenhouse effect would have had a significant impact upon the health of the plants. This would explain why the plants under containers with less volume had a higher percent of growth than those under containers with more volume. The greenhouse effect would cause the heat produced from the lamp to become trapped underneath the container with the plant. As more heat gets trapped and little heat escapes, the inside of the container gradually becomes warmer. The less volume the container is, the more heat is confined to a smaller area, causing the temperatures in the containers with less volume to become more heated than those with more volume. The plants underneath the smaller containers did better than the plants underneath the larger containers because the smaller containers had higher temperatures, which caused the plants to prosper; not because of the carbon dioxide
