FLOWER PROJECT

Will adding white vinegar to freshly cut flowers keep the flowers fresher?

If white vinegar is added to the water of fresh cut flowers, then they will last longer than flowers in normal water because the vinegar will prevent microbe growth.

MATERIALS

• Vinegar
• Water
• Measuring cup and spoons
• Two vases
• iPad (for photos)

PROCEDURE

• Buy freshly cut roses
• Place three tablespoons of vinegar to one cup water in one vase
• Make another cup but fill it with normal water
• Place three roses in the vase with the water, this will be our control group, lable it control
• Place three roses in the vase with white vinegar, this will be our experimental group, label it experimental

PROCEDURE

• Record quantitive data for seven days recording and photographing the evidence the number of fallen petals and the number of petals that remain the same color
• Record qualitative data recording the color of the bloom and odor of the bloom

The independent variable is the tree table spoons white vinegar in one cup water.

The dependent variable is the time it takes for the flowers to wilt.

Control group is the flowers in normal water

The experimental group is the flowers in white vinegar and water

Controlled VARIABLES

• The same amount of flowers
• The same amount of water in the vases
• The time of soaking
• Same location kept
• Same type of vases

The major changes I observed was on the fifth day the control flowers started to wilt after four days of perfect condition. The results surprised me because the experimental flowers wilted after 2 days. I think that the results happened because the vinegar probably overpowered the water and drought the flowers. I did not have any unexpected variables in my experiment.

The hypothesis was that adding white vinegar to fresh cut flowers, than it will keep flowers fresher because the vinegar will prevent microbe growth. The results did not support the hypothesis because the experimental flowers started to wilt after two days in white vinegar and water. The experimental flowers turned tan and white and the stem drooped. If the experiment would be done again, less white vinegar should be added to prevent overpowering of the water and giving more water to the flowers will help dilute the vinegar.
