Bean Plant Experiment
For this experiment, I needed to plant some beans. I did this using plastic planting cups, potting soil, and beans provided by my professor. I also would need to set up my experiment, which I did by building saran wrap tee-pees. I used dowel rods to construct the basic frame of the tee-pee, and held it together using duct tape. I then proceeded to wrap the frame in saran wrap. I did this four times, once with red saran wrap, once with blue saran wrap, once with green saran wrap, and once with clear saran wrap, which would be my control. I planted three seeds in each of the eight cups, and then placed two cups under each tee-pee. After the first week, I went out to my plants and removed all but one bean plant from each planter, and then replaced the planters under the tee-pee. I would water the plants every Monday and Thursday, and would make my measurements on Thursday. The measurements I recorded consisted of the height of the plant(from the soil to the apical meristem), the number of leaves, the average width of the leaves, and the average length of the leaves. I also looked at the plants and determined which looked healthier, based on my extensive working knowledge of plants from having grown m
When I measured for the third week, the order of increasing height was red, blue, control, and then green. The green plants had more and larger leaves than the other plants. The red plants were not as green as the control and the blue, and the green plants were slightly darker in color that the other plants, a sign that the plant is healthy. After the first week of growing, all plants had around the same height, the same number of leaves, and the same average width and length of the leaves. All plants looked healthy, all of which can be explained by the fact that the plants hadn’t had a chance to use the sun for their source of energy yet, they were still using the stored energy of their seed. This experiment conclusively proves that the wavelength of light most used by plants is in the red part of the visible light spectrum. This is shown by the fact that the plants wrapped in the red saran wrap did the worst, because the red light is reflected away, only allowing the rest of the colors through. The green wrap did the best because it reflected the green light away, what plants already do. It only allowed the wavelengths of light through that the plant could use. It is also worthy to note that the plants wrapped in green saran wrap grew better than the control. This proves that it is
