ACT Science Final Quiz 3 – Outschool

Ansley moved into a new home with a large yard. She enjoyed growing daylilies and wanted to find the soil that best promoted their growth before she invested in soil for several flower beds.

Experiment 1

Ansley built a 4 feet by 4 feet raised garden with a uniform depth of 1 foot and divided it into four quadrants. Each of the four quadrants contained a different type of soil. She placed a daylily in each quadrant. Each of the daylilies were the same species and approximately 10 inches tall. Each quadrant received approximately the same amount of sunshine and water.  She recorded the height, in inches, and total number of daylily buds at the end of each week for 3 weeks.

Experiment 2

To measure the effects of watering, Ansley placed two more daylilies that were approximately the same size in two separate pots. Both pots had the same type of soil and received similar sunlight. The daylily in Pot A received a cup of water each day for three weeks. The daylily in Pot B received 7 cups of water on the first day of each week. The height and number of buds for each plant were recorded throughout the three weeks.

Daylily in Pot B results:

From the results of Experiment 1, the daylily in which quadrant gained the most height from the week 1 to week 3 measurements?
