Explanation:

A dependent variable is what is being measured and is affected by the independent variable. In this experiment, Sally is testing how the type of light (independent variable) affects the height of bean plants. The height of the plant is what she measures, so it is the dependent variable. The amount of light is controlled, the type of light is the independent variable, and the type of plant is constant (bean plants).

Answer:

the height of the plant
