Suzie wants to know how different colors of light effect the growth of plants. She believes that plants can survive the best in white light. She buys 5 ferns of the same species, which are all appoximately the same age and height. She places one in
white light, one in blue
light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20mL of water
once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.
