Explanation:

In an experiment, the independent variable is the factor that is changed or manipulated by the experimenter to observe its effect on the dependent variable. Here, Nami is changing the amount of light, so it is the independent variable. A hypothesis is a proposed explanation, a control is a standard for comparison, and the dependent variable is what is being measured (plant growth in this case).
