Colorful Carnations
Biology
Mallory Running
The problem is that white flowers change colors in
colored water.
The project overview was that my hypotheses was
correct.
There are several different colors of carnations
Live in different climates
Live on average for seven days out of soil
Need LOTS of sunlight
Drink about 2 oz. of water a day
• Independent variable: the color of the water
• Dependent variable: the color of the flower petals
• Constant variables: amount of water, amount of
sunlight, type of flower, amount of food coloring,
temp. of water, temp. of air
• Control group: the group with no food coloring in
the water
•
• If you put blue food coloring in white
flower’s water, then the flowers will turn
blue because the plant with deliver the
colored water the petals of the plant.
Six glass cups
One bottle of neon blue food dye
Six white carnations
Six cups of water
Scissors
1. Cut six with
carnations to
7 in long each
2. Put one cup of
water into each
cup
3. Put on flower in each cup
4.Put four drops of dye in three of the
cups
5.Observ e data and take picture over the
course of three days

What I learned from this experiment is that plants
adjust to their surroundings rather quickly. The
data supports me hypothesis to be correct.
• One of the possible experimental errors is that the water
that I put into the cups was not exactly the same
temperature. This may have affected my data by causing
a chemical reaction with the dye, causing it to work
better on the flower or not work as well on the flowers.
• For future experiments, I would recommend not only
starting the whole project earlier, but to put more drops
of dye into the water.
