Dye rose experiment

 

Where does the water really go when a plant is watered?

With this experiment, the students discovered how essential the functions of stems are to plant growth.

As the colored water is absorbed, they were able to see how it moves into the flower and were amazed when the petals of a white rose changed color.

After having a small review about the flower system and explained the process of the experiment, we separated the students in eight teams and we supplied each team with the following supplies: Recording sheets White rose Plastic glasses Water Liquid food coloring in a variety of colors The instructions were the following: 1. To start they trim down the stems of the flower so they fit in the plastic glass. 2. Added water to each cup. 3. Then put about 10 drops of food coloring in the water and stir around. 4. Put the flower inside each glass of colored water. 5. Check in on the flowers every day and observe any changes. 6. Write observations. Observing the Flowers Change Color:
We did this color changing flower experiment in the morning and we started to see changes around 16:00 some of the flowers started showing faint streaks of color along their petals. By the next morning, most of them were even a little bit more colorful. The following day the color was a bit more vibrant. We continued to watch the flowers over the next few days. They rose was a bit brighter than the picture above, but never completely saturated in the color. Next time, we plan to try even more food coloring to see if we can get even more saturated colors.
