Hypothesis Of Plant Growth: Varying Light Exposures

Plant Growth; Varying Light Exposures

Intro and Hypothesis:
The problem that is going to be answered is: will plant seeds grow at differently if they are covered by different materials while exposing them to the same amount of light? Also, which material will allow the plants to grow the most, tin foil, saran wrap, paper or no covering? Before the lab took place, it was hypothesized that the less light a plant receives, the less it will grow and the more light it receives, the more it will grow. The possible solution to this problem is to cover different plants with different types of materials that pass different amounts of light. From general knowledge, the order of the amount of light each material passes through from least to most is
This shows that with the knowledge that since saran wrap passes more light than the paper, it can serve as proof of the hypothesis that the more light a plant receives, the more it will grow. One possible error in this experiment is the possibility of the coverings of the plants could have had an effect on the plants carbon dioxide intake which could result in smaller plant growth and different experimental results. Another possible error is if every single plant did not receive exactly 2ml of water, since a pipette is not extremely precise and there could be human error in this example and also generally throughout the
Therefore, the hypothesis is accepted because according to the data, saran wrap had the highest average growth while paper had the least average growth. From general knowledge, the order of the amount of light each material passes through from least to most is as follows: tin foil, paper, saran wrap, no covering. The data shows that the material that blocks light, paper, inhibits plant growth which is in accordance with the hypothesis. Additionally, the material that blocks almost no light, saran wrap, had the highest average
