Question

consider the scenario. a scientist sets up an experiment to see how colored lights affect the height of plant growth. he grows one group of plants in full sunlight, one group under red lights, one group under blue lights, and one group under green lights. all the plants are exactly that same type and all receive an equal intensity (brightness) of light. at the end of the experiment he measures all the plants. what is the independent variable? the type of plant the intensity of the light the color of the light the height of the plant

Explanation:

An independent variable is what the experimenter changes or manipulates. Here, the scientist is changing the color of the light to see its effect on plant growth. The type of plant and light intensity are kept constant, and the height of the plant is the dependent variable (what is being measured).

Answer:

the color of the light
