Q

A group of 5th grade students designed an experiment to determine the effect of fertilizer on plant growth. They obtained ten small pots and placed equal amounts of potting soil in each pot. They planted seeds in each pot and placed the pots in the same sunny area. Each day they watered the plants with an equal amount of water. They also added equal amounts of fertilizer to the plants. Each week they measured the height of the plants. After four weeks, the plants had grown an average of 6 inches and the students concluded that the fertilizer had a positive effect on plant growth. Which of the following would best improve the students’ experiment so that their conclusions are plausible and valid?
