Ben observed that puddles outside seem to disappear more quickly when it is a sunny day. He decided to test this by setting up an experiment in which he placed a graduated cylinder with 10 ml of water in a dark closet and a graduated cylinder with 10 ml of water by the window. Each day he measured the amount of water.
What did Ben change in this experiment?
the amount of sunlight on the water
the amount of water in the cup
the kind of cup
