Colorful Carnations Biology Mallory Running
Science Fair Project
Statement of the Problem The problem is that white flowers change
colors in colored water.
Project Overview
The project overview was that my hypotheses was correct.
Research There are several different colors of carnationsLive in different climatesLive on average for seven days out of soilNeed LOTS of sunlightDrink about 2 oz. of water a day
Variables
• 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
•
Hypothesis
• 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.
MaterialsSix glass cupsOne bottle of neon blue food dyeSix white carnations Six cups of waterScissors
Procedure 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

ConclusionWhat I learned from this experiment is that plants adjust to their surroundings rather quickly. The data supports me hypothesis to be correct.
Possible Experimental Errors
• 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.
Applications and Recommendations• For future experiments, I would recommend not
only starting the whole project earlier, but to put more drops of dye into the water.
