Conclusion:
The purpose of this experiment was to see what color of light will make grass grow the fastest, and to prove my hypothesis was correct. Some of the major findings that occurred during the experiment were the color of the grass changed. Instead of being green, it was yellow. Also the grass was somehow pushed down flat to the soil. The grass would not stand up like normal.
My hypothesis was that red colored light will make plants grow the fastest. My data from the experiment proves this because red was in a tie for first with blue and white. We noticed that since the grass was put in a carbon dioxide environment, that might have affected the results since plants are used to the air outside. Also because the plants were covered with a cardboard box there was not a lot of air, besides a few cracks in the sides of the cardboard. From these results, I can conclude that scientists have done the correct research in the past that red light produces a plant, and blue light creates the leafy part of a plant (since grass is all leaf). I didnt understand how white could have also been in first, but then I remembered that white light is a mix of all the colors of the rainbow put together, so I figured that thats why you may hear people say, plants need sunlight!
If I was to do this experiment all over again, I would decide to find a way to let more air reach the plants. That way it will be more of an outside setting. Also, I would try to use soil that didnt have any fertilizer in it so that the grass is growing on its own, not by the help of nutrients. If I tried using the same water amount and cycle for each plant, that would help with finding a more accurate conclusion to my experiment.
