Title: Why do cut flowers have a real sweet tooth when it comes to sugar?


1
Why do cut flowers have a real sweet tooth when
it comes to sugar?
  • Catherine Aber
  • Mr. Kuhne
  • Lopez Elementary

2
Statement of the Problem
  • Cut flowers are gifts that you can give to
    someone when you are congratulating them or just
    letting them know you care about them.
  • But usually cut flowers die shortly after you
    receive them.
  • Is there a cheap way to keep cut flower stems
    alive long enough?

3
Project Overview
  • This project interested me because I wanted to
    find a way to keep cut flowers alive longer.
  • Cut flowers usually wither and die after a
    very short time.
  • I gathered information and performed
    experiments.
  • I created a graph and table that were
    helpful when coming up with conclusions.

Background Research
  • Plants make sugars in a process called
    photosynthesis.
  • Photosynthesis requires the usage chlorophyll in
    green leaves to trap Energy from sunlight.
  • Carbon dioxide and water are then converted to
    sugar using the absorbed energy.
  • Cut flowers depend on sugars which they break
    down to provide energy to live longer.

5
Background Research (continued)
  • Sugar is one of the nutrients cut flowers need to
    live longer than usual.
  • Florists give you little packets that supply
    nutrients and other important assets.
  • It will be helpful to find a cheap way to use at
    home to keep cut flowers longer at home.

6
Variables
  • Controlled Variable The variable that I kept the
    same during the experiment is the amount of water
    that was in the vases because that is not what I
    am testing.
  • Independent variable The one variable that I
    purposely changed was the amount of sugar each
    bouquet of flowers had to see which lived the
    longest.
  • Dependent variable The measure of change
    observed because of the independent variable was
    that some plants were dying before others. This
    was because they each had different amounts of
    sugar.

7
Hypothesis
  • If I put sugar in the water the cut flowers live
    in, then it will survive longer than the cut
    flowers with just water.

8
Materials
  • Where I will get them.
  • Sugar Bowl in kitchen.
  • Florist or Grocery Store.
  • Supply Cabinet in Kitchen.
  • Water faucet in kitchen.
  • Kitchen Cabinet.
  • Come with Store flowers.
  • Reading room printer.
  • Reading room cupboard.
  • Materials needed.
  • 1,2, and 3 tsp. of Sugar.
  • 2 bouquets of cut flowers.
  • 5 glass vases.
  • 6 cups of water.
  • Measuring Cups.
  • Commercial Floral packet.
  • Small rectangular pieces of paper.
  • Tape dispenser.

Procedure
  • Step 1. I gathered all my materials and then
    put the bouquets of cut flowers into the 4 glass
    vases.
  • Step 2. I put 2 cups of water into each of the
    glass vases.
  • Step 3. I put 0, 1, 2, and 3 tea spoons of
    sugar into the water and so I didnt forget how
    much sugar each bouquet got, I labeled the vases
    with pieces of paper and stick it on with
    tape.
  • Step 4. I continuously recorded the days that
    they lived.
  • Step 5. I made a table and graph of my
    observations and conclusion of my hypothesis.

Conclusion
  • What I learned from my project
  • -sugar can help make cut flowers live longer
  • -sugar supplies the nutrients they need to
    survive.
  • -my hypothesis was proven because the vases
    with sugar lived longer than the vase with
    water.
  • -this would benefit our society in that it
    would be useful to know how to help keep cut
    flowers that you get for gifts healthy longer.
  • -what I would do differently if given the chance
    is use other mineral nutrients with the sugar
    water and see if flowers survive longer than the
    vases with sugar water.

Acknowledgements
  • There are several people that I would like to
    thank who made this experiment possible. First of
    all, I would like to thank my mom, because she
    put the experiment together by helping me gather
    the materials and track the days. Also I would
    like to thank my dad, because he bought the
    materials and helped me with my PowerPoint. I
    would also like to thank my sisters because they
    helped me take pictures of my observations and
    with my Poster Board.
