Identify the controls and constants in the following experiment.

To determine the effects of fluid intake on urination rates, 10 students were given varying amounts of water. 3 students had no fluids. Everyone drank nothing before the test began. Nor did they eat anything. The student were to sit quietly at their desk. Data was collected by measuring the total amount of urine.

The control was the set of 3 students who had no water and a constant was having all students sit quietly at their desk

The constants were not drinking before the test, or eating before the test and sitting quietly at the desk, but there was no control group

The constant was the set of 3 students who had no water and a control was having all students sit quietly at their desk
