HYPOTHESIS If plants are grown under red, blue, or yellow light, the photosynthetic rate will increase more than if the plants grown under white or green light. EXPLANATION The relationship between plant growth and light can be determined when plants are grown under different colors of light. Plants need light for photosynthesis. The three colors red, blue, and yellow are used most by plant leaves, which means that these colors are absorbed. For example, leaves appear green because green is the color reflected by the plant’s leaves, while the other colors are absorbed. INDEPENDENT VARIABLE The Independent Variable is the color of light each plant is exposed to. Six groups of two will each receive a different color of light. Group A will be exposed to a red light bulb, group B will be exposed to a blue light bulb, group C will be exposed to a yellow light bulb, group D will be exposed to a green light bulb, and group E will be exposed to a
