DOL: I will accurately identify the major parts of experiments for 3 of 4 trials.
Experimental Design Worksheet
For the remainder of the class you will work on completing your hypothesis, variables, and experimental design for your Science Fair project.
A two page summary of research is due by Friday with a complete, MLA formatted bibliography (works cited page). You can use Citation Machine to help. Your bibliography must include at least 3 sources, 1 print and 2 internet.
1. Plants grow best
in white light.

Read the following
situation and answer the following questions.
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.
