B: Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately 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 20 mL of water once a day for 2 weeks. After
the two weeks, Suzie observes the plants and makes measurements.
Hypothesis:
Independent Variable:
Dependent Variable:
Control Group:
Experimental Group:
L
What could be the controlled variables?
What types of measurements can Suzie make on the plants to determine how they did in different types of light?
