Trevor wanted to determine which fertilizer worked best for growing plants. He planted sunflower seeds, marigold seeds, and Petunias seeds in separate pots. In one pot he used Miracle Grow, Scotts Fertilizer in another, and no fertilizer in the third pot. He watered the plants the same amount of water each day. After a month, he measured and recorded the plant's height. What did Trevor do wrong in this experiment?
The pot sizes were too big.
He did not give the plants enough time to grow before measuring the heights.
He should have used a different amount of water for each plant.
He has more than one independent variable.
