The dependent variable is the variable that is measured during the experiment. In this experiment, the dependent variable is the AMOUNT OF PLAQUE LEFT IN ALEX'S TEETH.

The control group in an experiment is the group that does not receive the treatment/independent variable. In this case, the usage of WATER is the control.

The constant is the variable kept the same for all the groups in the experiment. In the case, the Same amount of time for each product to have an effect on her teeth is the CONSTANT.
