Four test tubes with 20mL of water and cut flowers were set up. Three of the test tubes had food coloring added. You observ the flowers that were placed in the test tubes for the following five days. You record your observations each day at 10:00am. On the fifth day, the flowers in the colored test tubes began to turn the color of the liquid in which they were placed. You hypothesis was: IF cut flowers are placed in colored water, THEN the flower petals will absorb that color throughout the petals. Experimental Design In this experiment, one of the constants was: O 10:00am O The test tube without food coloring O The ending color of the flowers O The color of the water
