Students in Mr. Manini’s class were testing whether plants need light to grow. In the experiment students took two identical pots and filled them with equal volumes and masses of soil. The students planted the same number of seeds in each pot. They measured the water to be used in the two pots and watered the plants each day with the same amount. One of the pots was placed at the window, and the second was placed in a dark closet. Which part of the experiment represents controlling variables?
A. Changing the placement of the plants with one on the window sill and one in the dark closet.
B. Measuring the same volume and mass of soil, water, and number of seeds planted.
C. Both A and B above
D. Neither A nor B represents controlling variables
