Molly is experimenting with water. She wants to see if the rate of evaporation changes when water is covered. She pours 50 ml of water into each of 3 cups. She leaves one uncovered, covers one with plastic wrap, and covers the last with a paper towel secured with a rubber band. She makes a hypothesis that the water in the uncovered cup will evaporate the fastest. She leaves all the cups in the same place. After 24 hours, she compares the water level in each cup and notices that the uncovered cup has less water in it than the others. The cup covered with plastic wrap has evaporated the least, leaving the most water in that cup.
