A student set up an experiment to test if plants give off water vapor. Fifty pea plants, growing in pots, were covered with individual glass containers and left overnight. The next morning, the inside of each lid was covered in droplets of water. The lab student concluded that plants generally give off water vapor. What critique would you make of the experimental design?
A. The student did not have a clearly stated hypothesis before beginning the experiment. B. There was no control so the water could have come from other sources such as air in the jar or the soil. C. The experiment was not precise, meaning it was not reproducible. D. There was not a large enough sample of pea plants used to get adequate data.
