A group of students wants to investigate the effects of plant moisture on the growth of caterpillars. The students fill three identical boxes with an equal number of a kind of leaf that caterpillars eat. The students keep the leaves in the first box dry, spray the leaves in the second box with two sprays of water, and spray the leaves in the third box with four sprays of water. The students then add four caterpillars to each box. Every day, the length of the caterpillar is measured, recorded and the results are averaged. What is the tested (independent) variable in this experiment?

In the given experiment an independent variable is the growth of caterpillar.

Variables are those quantities which will not have permanent value else they will have different values at different conditions.

Variables are also of two types:

Dependent variable: This variable changes its value according to the particular condition as in the given experiment leave is the dependent variable, because survival of leaf depends on moisture.
Independent variable: This variable changes its value time to time but doesn't depend on any particular condition as in the given experiment caterpillar is the independent variable as their growth is not depend on any condition.

Hence caterpillar is the independent variable.
