Question

You've made the hypothesis that the less rainfall a cactus plant gets, the taller it will grow, since cactuses like dry conditions.
What should be the independent variable in an experiment designed to test this hypothesis?
A. the height of the cactus plants
B. the hours of sunlight the cactus plants get
C. the amount of rain falling on the cactus plants
D. the type of soil the cactus plants are growing in

Answer 1

Answer:

C

Explanation:

because independent variable is what we change

Answer 2

C. the amount of rain falling on the cactus plants

Explanation:

The amount of rain falling on the cactus plant is the independent variable in this experimental design.

The height of the cactus plant is the dependent variable here.

• An independent variable in an experiment is the cause of a change.
• The dependent variable is the effect of the change produced.
• The amount of rain that falls affects the growth of the cactus plant.
• This is clearly the independent variable in this design.
