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

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.

In this investigation, the independent variable is represented by the different liquids (Option C).

The independent variable is the variable that isn't changed by the other variables during the experimental procedure.

Conversely, the dependent variable is the variable to be measured or tested during the experiment (in this case, plant growth).

Thus, the independent variable is the variable expected to be the “cause” of the change in the dependent variable.

In conclusion, in this investigation, the independent variable is represented by the different liquids (Option C).
