what is the independent variable? (sci.sep3.a.m)
a) the size of the pot
b) the amount of water each plant receives
c) the height of the plant
d) the type of soil

Explanation:

To determine the independent variable, we recall that the independent variable is the factor that is manipulated or changed in an experiment. In this case, the student is changing how often the plants are watered (daily vs. every three days), which affects the amount of water each plant receives. The size of the pot (a), height of the plant (c), and type of soil (d) are either controlled variables or the dependent variable (height). So the independent variable is the amount of water each plant receives.

Answer:

b) The amount of water each plant receives
