An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, same amount of sunlight, and the same amount of liquid. In this investigation, what is the independent variable?

A. type of plant

B. plant growth

C. different liquids

D. amount of sunlight

A. type of plant

all the other variables have to stay in the same exact amount or else changes the identity of the experiment

C. different liquids

Explanation:

An experiment has two variables: dependent and independent variables. An independent variable in an experiment is the one that is changed to observe the effect of the change on the dependent variable.

In the given experiment, different types of liquids are used to show their impact on plant growth. These different types of liquids (water, apple juice, or milk) are the independent variables while plant growth is the dependent variable.
