a)
control variable (s)
b)
independent variable

3.
A pair of researchers are wanting to see the effect of carbon dioxide on the growth of plants. They use a greenhouse to create an environment with an elevated carbon dioxide levels. In another greenhouse, they monitor the gases to keep carbon dioxide levels to a normal level. They keep the humidity, the sunlight levels, duration of light, water, and fertilizer the same between both groups. The researchers recorded the height, leaf numbers, and change in mass of the plants in each greenhouse. In this experiment, what is the independent/experimental variable?
a)
the fertilizer
b)
the amount of carbon dioxide
c)
the number of leaves
d)
the amount of oxygen
