In an inquiry lesson, the teacher noticed Keysha as she was conducting and experiment in which she obtained two thermometers and recorded the starting temperatures of each. Keysha then placed one thermometer near the ceiling and the second near the floor. After 15 minutes, she observed the thermometers and again recorded the temperature. In comparing the temperature change in the thermometers in the two locations, Keysha observed that air near the ceiling was 2 degrees warmer than the air near the floor. She concluded that warmer air rises and stays near the ceiling, while cooler air sinks and stays near the floor. Although her conclusion is scientifically accurate, what was the major flaw the teacher should have noticed with Keysha’s experimental procedures?
