Jim wanted to test the effect of different amounts of water. He tested four pots of plants with 5 plants each, group one got 10mg of salt in 100ml of water, group 2 got 5mg of salt with 80 mL of water, group, 3 got 75 mL of water with 100mg salt, and group 4 got 100 mL of water . Was Jim's experiment on the growth of sunflower plants well-designed?
Yes, because he had three trials.
No, because he changed the amount of salt he used for each plant.
Yes, because he observed and measured the plants for one month.
No, because he changed the amount of water he applied to each plant.
