Question
Denise wants to find out how the steepness of a hill's slope affects the amount of soil that erodes from it. She will use soil, a long pan, and several 4-inch-tall wooden blocks to build a model hillside. She will use a watering can to simulate rainfall.
In her experiment, which factor should be Denise's variable?
A.
the type of soil with which she fills the pan
B.
the location she uses to test her model
C.
the number of blocks holding up the end of the pan
D.
the amount of water she pours on the model hillside

The variable in Denise's experiment would be the factor that she changes in order to observe its effect on soil erosion. In this case, the amount of water she pours on the model hillside is likely to affect the soil erosion due to its impact on how steeply the soil is washed away.
Thus, the correct answer is:
**D. the amount of water she pours on the model hillside**.
Thus, the correct answer is:
**D. the amount of water she pours on the model hillside**.
