Growing Plants in Colored Lights

Data Analysis
How Plants Grow:
How does the color of the light affect plant growth?
Plants use energy from different light wavelengths to break down water and carbon dioxide to create glucose through a process called photosynthesis.
Independent Variable: Colors of the lights

Dependent Variable: Height of the plants

Control Group: Basil plant grown under white light
If the color of light affects the rate of photosynthesis, then increasing the exposure of red light on a plant will increase the growth rate of the plant.
- 2 Pre-potted, growing Basil Plants
- Red Light
- Normal (White) Light
- Ruler (cm)
- Measuring cup
- Water
To test if the color of the light affects plant growth, two identical pre-potted and actively growing plants (basil) will be grown under separate lighting and their growth measured daily for five days. One plant will be placed under normal (white) lighting conditions, the second plant will be placed under a red light. The height of the plants will be measured from the plant base to the highest tip and recorded each day. After five days, the heights of the plants will be compared. Each day the plants will receive 1/2 cup of water.
Plant Heights (cm) Over 5 Days
The basil plant under the red light did grow taller.
The data from the experiment supported the hypothesis that the plant grown under a red light would grow faster than the plant grown under normal (white) light. This is seen through the data, at the end of 5 days, the basil plant grown under red light increased 20cm in height while the basil plant grown under white light increased only 10 cm.
The plant cells had more readily available light energy under the red light than the white light, meaning that more energy could be made for the plant to use for growth.
Another experiment that could be done would be to grow many basil plants under different colored lighting to see which wavelength plants can utilize best for growth.
