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

The answer would be c, the ammount of rain falling on the cactus plants

Answer 2

So the independent variable is the thing that is changed in an experiment and you want to change the amount of rainfall the cactus gets as the hypothesis is about rainfall so the answer would be c). Hope this helps :)
