The purpose of this experiment was to determine the effect of different colored lights and the growth rate of radishes.
I became interested in this idea when my mother and I were planting a garden and we wanted to find out what we could do to increase the growth rate.
gained from this experiment may help gardeners/farmers grow plants at a
more rapid pace.
My hypothesis is that red light will increase the growth rate of radishes the most.
I base my hypothesis on a small but similar experiment my homeroom class did with, bean seeds.
The constants for all groups in this experiment were:
The responding variable was the growth of the radishes in centimeters from the tip of the root to the tiptop of the plant.
To measure the responding variable I used a meter stick with centimeter accuracy
The original purpose of this experiment was to figure out if the color of light would increase the growth rate of radishes.
of the experiment, as indicated in my table and graphs, are the lighter
the color the healthier, stronger, and taller the plant. The colors
of light that had the most effect on the growth of the radishes were
the clear and the yellow light
My hypothesis was that red light would increase the growth rate of radishes the most.
The results indicate that this hypothesis should be rejected. The lighter the color of the light the better the plant grows of this experiment.
Because of the results of this experiment, I wonder if different radish seeds would change the out come.
If I were to conduct this project again I would use a different kind of seeds and see if the growth is as fast, I would also use more of a variety of colors.
