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.
Which question best describes John's experiment?
Does the amount of oxygen affect the amount of light needed by the plant?
Does a plant produce more oxygen when it is placed closer to a light source?
How does the type of plant affect the oxygen produced when placed by a lamp?
Will the light affect how much the Elodea plant grows when placed in the light?
