Color Changing Carnations
Summary of Research
The reason we believe the flowers will take the color of the dyed water is because flowers soak up the water they are put in. They then distribute that water to the different parts of their frame. The water moves from the bottom of the stem and up to the flower’s petals. The water is also distributed to the leaves.
Before the flowers are put in the dyed water, they already have some water in the stem, leaves, and petals. The already present water will begin to evaporate. The evaporating water leaves the flower through small, pore-like openings spaced throughout the flower. These openings are called stomata. The overall process is called transpiration.
As transpiration takes place, the evaporated water is replaced by the water surrounding the opening at the end of the stem. As a result, the dyed water surrounding the opening at the end of the stem will have the opportunity to disperse itself throughout the flower. It will reach the
petals eventually, and change their color. Water travels from the opening at the end of the stem and up to the petals through small, tube-like structures inside the flower. These tube-like structures are called xylem.
Xylem are spread throughout the flower much like the veins in our body are spread out, that would be all over. All the xylem are started from the opening of the stem. From there, they travel up to the petals, some breaking off into the leaves. The rate at which the xylem take in water and carry it along is dependent on the transpiration rate.
Transpiration rate is dependent on several factors. One of them being the size of the flower. Two others being the amount of stomata and the amount of sunlight. The greater the transpiration rate, the quicker the xylem will drink up the water. The quicker the xylem drink up the water, the quicker the flowers will take the color of the dyed water.
Because we could not find any information on how to reverse the dying of the flowers, we had to go off what we had just learned. We believe the petals can be stripped of their new-found color through the same process in which they changed color.
The colored water in the flowers will be evaporated and replaced with the clear water the flowers are put in. The transpiration process will happen all over again. The dyed water will evaporate through the stomata. Clear water will then be soaked up and travel through the xylem, up to the petals to reverse them back to their starting color.

Executive Summary
In our project, we experimented on changing the colors of flowers’ petals. What we really kept our eye open for was how different combinations of dyed water and petal colors would produce varying products. We really wanted to put on display the differentiating effects these two constants with a noticeable variable had on each other.

If we mix different petal colors and dyed waters together, the petals will take the color of the dyed water. Based on the research, we should also be able to reverse the dying of the petals through nearly the same process in which the petals were dyed.

• cups
• flowers, carnations, different colors (12 total)
o 3 yellow
o 3 white
o 3 pink
o 3 red
• food coloring
o red
o green
o blue

I. Put water into three cups, each amount in all cups being equal.
II. Dye one cup of water red, another green, the last one blue. (15 drops of food coloring)
III. Mix the dyed water.
IV. Put one of each color flower into one of each cup of the dyed water.
V. Leave flowers in a well lit room for 4-6 hours.
VI. Take pictures every hour.
VII. After the appropriate time, dump the cups of dyed water. Keep the flowers.
VIII. Fill each cup with clear water now. Keep all amounts equal.
IX. Check on cups after 4-6 hours to see if dyed petals have been reversed.

Summary of Results
Flowers Placed in Dyed Water
Yellow flower that was put in green dyed water.
White flowers, one from each cup of dyed water.
Yellow flower placed in blue dyed water.
Pink flowers, one from each cup of dyed water.
Pink flower that was put in blue dyed water.
Red flower that was put in green dyed water.
Red flower that was put in blue dyed water.
Overall, the experiment went well. Our hypothesis was right, but not. The flowers did take the color of the dyed water. The part we were wrong about was being able to reverse the dying of the petals. Maybe because the dye separated from the water when the water evaporated from the petals to stain the petals. That’s just a theory.
One thing we would like to change about our experiment is the environment in which we conducted it. We conducted it inside using no real sunlight. The results may have been different, better, if it was done outside. We’d also like to leave the flowers longer in the water before switching them out. Next time, we could also measure how much water the flowers had soaked up.
