Water Flow In Plants

Big Question

• Will food coloring travel through a flower stem?
• I am going to find out if food coloring is added
  to water whether or not it will the change the
  color of the flower.

3
Hypothesis

• The water will travel from the glass to the
  flower making it change color.
• Just like water, food coloring will travel up the
  stem and into the flower.

5 interesting facts

• 1. The carnation, dianthus caryophyllus, is one
  of the oldest known plants in the world, with its
  roots from the Mediterranean.
• 2. Both the ancient Greeks and the Romans
  cultivated the plants for use in flower garlands
  for décor and art.
• 3. The carnation is a perennial plant that comes
  in many colors.
• 4. The white carnation evolved during modern
  times as the color palette of the plant expanded.
• 5. Today, the carnation carries various meanings
  and associations.

5
Experiment

• Materials
• Four vases
• Four white carnations
• Water
• Food coloring

6
Experiment

• Step-by-step instructions
• 1. Pour water into each vase.
• 2. Add three to four drops of food coloring into
  each vase.
• 3. Cut the stem into half lengthwise from the
  bottom to halfway up the flower.
• 4. Place a flower in each vase.
• 5. Let the flower stand in the water for 48 hours.

7
Experiment

• Control/variables stated
• Control group is the carnation that did not get
  food coloring.
• The variables in this experiment are the
  different food colorings red, blue, yellow, and
  green.

4 Observations

• 1. This experiment took 48 hours.
• 2. The colors turned out pretty.
• 3. Some flowers took longer to change color.
• 4. The longer the flowers were in the food
  coloring and water the more they changed color.

9
DATA

• The first 24 hours of the experiment there were
  not a lot of color changes occurring in the
  flowers. The first part of the flower to change
  color was the edges and gradually the whole
  flower began to change to the color of food
  coloring placed in each vase.

10
Analysis of Data

• Did the experiment test your hypothesis?
• Yes, but I thought the flowers would change
  colors faster. The change took place over
  several days, and I thought it would take two
  days.
• How did you know?
• The experiment took longer than I had predicted.
  

11
Conclusion

• Was your hypothesis correct? Yes.
• What would you change in the experiment and why?
• I would change the amount and colors of food
  coloring added to each flower. I might try
  adding several colors to one flower to see what
  changes would occur.
• What are some new questions you have?
• I still wonder exactly how this works.
