__independent variable__is the quantity which is changed by the scientist or the person doing the experiment. The__dependent variable__is the quantity which changes in response to the change in the independent variable. For instance, if I want to test how the amount of water I give a plant affects the height of the plant, the independent variable is the amount of water I give the plant, and the dependent variable is the height of the plant.What about our Thumb Wars experiment? Which are the independent variable(s), and which are the dependent variable(s)? Match each variable with its category in the self-quiz below.
