One of your classmates suspects that ants might be attracted to the scent of sugar cookie candles. They collect two hundred ants and set up a wooden bridge that leads from the glass rim of a lit candle to the rim of an empty glass jar. Then, they test one hundred ants by placing each ant on the center of the bridge and recording which side the ant crawls to. As a control, they test one hundred ants using a bridge between two empty glass jars. What is a flaw in this experiment?
