Science Project with a Control

Control and cups 1-4

Cups 3-5 and the Mystery Cup

We are learning about having a Control in a Science Experiment so we did a Science Project with Carnations. We put 1 carnation in plain water. Then we put 5 carnations in water (each glass had 2 cups of water) with red food coloring (the first glass had 1 drop of coloring per cup of water, the second glass had 2 drops of coloring per cup water, the third glass had 3 drops of coloring per cup of water, the fourth glass had 4 drops of coloring per cup of water and the fifth glass has 5 drops of coloring per cup of water). We had an extra carnation so we did a mystery color (6 drops of blue and 6 drops of red food coloring). Our experiment was to see if the coloring in the water would change the color of the leaves of the carnations. We found that the water does change the color of the veins in the carnations and the tips but not the whole leave of the carnation. The more food coloring the darker the the color. Cup 1 (not the control) and cup 2 (also not the control) the veins color change was hardly noticeable due to the small amounts of food coloring in the water. In the Mystery cup, surprisingly the color was not purple that we got but more bluish. This was very noticeable but like the other the color only was in the veins and the tips of the carnation. We also noticed that after the week was over the only flower not dying was the control, we feel that the food coloring was poisoning the flowers.
