H- The plant does differ the height of a plant Null- There is no relation
tomato plants of the same height were placed in the same size pots, in the same type of soil and each was given the same amount of water. Each plant was under a light bulb of the same intensity as the other but each light was a different color. Each day, the plants were given light for 12 hours and left in darkness for 12 hours. the height of the plant was measured in centimeters at the end of each week for 10 weeks.

Independent variable- Colour of the light Dependent variable- Height of the plant
Five tomato plants of the same height were placed in the same size pots, in the same type of soil and each was given the same amount of water. Each plant was under a light bulb of the same intensity as the other but each light was a different color. Each day, the plants were given light for 12 hours and left in darkness for 12 hours. the height of the plant was measured in centimeters at the end of each week for 10 weeks.
