Sally loved flowers and grew many in her flowerbeds on the windows of her house. She wanted her flowers to grow more quickly and she wondered if fertilizer could help. She guessed that it would, because she saw commercials on television. So, she went to the store and bought fertilizer. She put the fertilizer on one of her flowerbeds. She watered all of her flowerbeds with the same amount of water. She measured the height and width of the plants daily. She noticed after two weeks that the plants with fertilizer did grow more quickly than the flowers without, because the plants with fertilizer measured taller and wider than the plants without. She decided she would try this fertilizer on a few of her house plants and look for results too.
