Mr. Smith wanted to see if the color of light shined on a plant had an effect on the number of leaves it had. He gathered 2 groups of the same species of plants, gave them the same amount of water, and did the test for the same amount of time. On one group of plants he used white light. For the second group he changed the light color to red.

Answer:

This question is asking to identify the following variables in the question;

Independent variable: COLOR OF LIGHT

Dependent variable: NUMBER OF LEAVES OF THE PLANT.

Constant: SAME SPECIES OF PLANT, SAME AMOUNT OF WATER

Explanation:

Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the COLOR OF LIGHT is the independent variable because it is the variable that was changed

The dependent variable is the variable that is measured in an experiment or the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the NUMBER OF LEAVES OF THE PLANT.

The constant is the variable that is kept unchanged by the experimenter throughout the experiment. In this case, the SAME SPECIES OF PLANT, SAME AMOUNT OF WATER are the constants.
