Question
Vanessa is conducting an experiment to see how exposure to different types and amounts of light affects the growth of plants. Her results are shown in the data table below.
Light Source Type of Plant Growth
(centimeters)
Sunlight Pea Plant 1.09375
Partial Sunlight Daffodil 0.81250
Artificial Light Lima Bean Plant 0.78125
No Light Sunflower 0.18750
Did Vanessa make an error in the design of her experiment?
A.
Yes; plants cannot grow in artificial light.
B.
Yes; there are too many manipulated variables in her experiment.
C.
Yes; Vanessa should have measured with customary units.
D.
No; Vanessa designed her experiment correctly.

D. No; Vanessa designed her experiment correctly.
Vanessa's experiment appears to be well-structured, as she is examining how different types of light affect the growth of various plants. There is a clear manipulation of the independent variable (the light source), and growth measurements were taken for each plant type under distinct lighting conditions. There is no indication of multiple manipulated variables affecting her results, and measuring in metric units is appropriate for scientific experiments. Thus, option D is the correct choice.
