Tori heard an observation from a student in class stating that drinking body armor hydrates you after a workout better than water or Gatorade. After some research, she makes the assertion that Body Armor hydrates you more than any other sports drink or just plain water. She then begins to design her experiment. Match the parts of the experiment to the experiment she plans to conduct.
