Restate your hypothesis HERE (just copy and paste from above): If plants are exposed to blue light, then they will experience the most growth because blue light is the most beneficial wavelength for photosynthesis. If plants are exposed to green light, then they will experience the least growth because green light is the least effective for driving the process of photosynthesis.

Question

1. Which variables did you control in your experiment and which variable did you change in order to compare your growth results?
Answer:

Answer 1

In this experiment, the variables that were controlled included the type of plants used, the amount of water given to each plant, the type of soil used, and the amount of exposure to light. The variable that was changed in order to compare growth results was the color of light exposure - blue light, red light, and green light.
