In science class, the teacher was conducting an experiment to determine if blowing air causes water to evaporate faster then if there is no blowing air. She used one dish of water that was placed in front of a fan and another dish of water that was placed in a still location, so there would be no air blowing around it. What is the control in this experiment?
