RETAKE Quiz- Scientific Method

One day you notice that your plant that is 15 feet from the window is not looking too good. On the verge of death... You ask yourself, "What if I put the plant closer to the sunlight, then it will grow and become healthy again. You decide to test your hypothesis and get 3 of the same plants and measure their starting height. You place each plant at the following distance from the window: (A)0 feet, (B)5 feet, (C)10 feet and (D) 15 feet (original). You continue to give the plants 15mL of water at the same time each day, for a month.

After a month, you measure the height of each plant and record the following:

A = Start - 10 inches, FINAL 17 INCHES

B = Start - 8 inches, FINAL, 17 INCHES

C = Start - 9 inches, FINAL 11 INCHES

D = Start - 5 inches, FINAL = DEAD
