What scientific question is the above experiment attempting to answer?

John believes the water plant Elodea will produce more oxygen when placed closer to a light source. He places four Elodea plants of the same height at varying distances from a lamp: 1 meter, 2 meters, 3 meters, and 4 meters. The plants are in identical aquariums with a beaker placed over each plant. The oxygen content inside the beaker is measured after each plant sits for 8 hours.
