Select the correct answer choice for each question below.
1. A scientist observed his pepper plant leaves were turning yellow. He hypothesized that the plants were
getting too much sunlight. He conducted an experiment to find out if this was true. He put one pepper
plant in the shade and one pepper plant in the sun. He watered the pepper plants in the shade with one
cup of water once a day. He watered the pepper plant in direct sunlight with two cups of water once a
day. He then observed the plant leaves for two weeks recording their color. What error did the scientist
make in his experimental design?
A. The scientist did not water the plant in direct sunlight enough and the direct sunlight dried out
the plant.
B. The scientist needed to use three plants in his experiment - one plant in the shade, one plant in
the sun, and one plant in partial shade.
C. The scientist watered the plants with different amounts. All of the variables should be kept the
same between the trials.
D. Nothing is wrong with the experiment.
