Variables:
Procedure:
1. Make individual cubbies for each plant so that light exposure is controlled
2. Place one plant in each cubby
3. Expose each plant to a 50W light bulb, each of a different cover
4. At 7:30 each day, measure the mass of the plants and record in data table
5. Water with 50ml of water every day at 8:00
6. Repeat 1-5 for a week
7. Record data and analyze to determine the relative health of the plants based on the color of light exposed.
