FLOWER PROJECT

WILL SPRITE MAKE A FLOWER STAY FRESH LONGER?

The hypothesis is if a vase is filled with half Sprite and half water, then the flower will last longer because the Sprite will kill the germs in the water.

MATERIALS

• Four roses from the same batch
• Seven cans of sprite
• Two identical vases
• Five jugs of water
• An area with sunlight, big enough to fit two vases
• Time
• Camera
• Scissors
• Ruler

PROCEDURE

• Get four roses from the same batch.
• Get a box of seven cans of sprite.
• Get five jugs of water.
• Trim all roses to 25 cm.
• Make two groups with two flowers in each and label one the experimental group and one the control group.
• Place each flower group in marked vases
• For the experimental group, fill half the vase with sprite and the rest of the vase with water.
• For the control group, fill the vase full with water.
• Take pictures of the roses at the same time everyday for seven days.
• Record how straight the stem is, the texture, how many petals turned brown, how many petals fell for the next seven days.
• Refill the vase everyday and follow step 7, 8, 9, and 10 for the next seven days.

VARIABLES AND CONTROLS

INDEPENDENT VARIABLE

• The independent variable is the vase half filled with Sprite and half filled with water.

DEPENDENT VARIBLE

• The dependent variable is how the roses look everyday.

CONTROL GROUP

• The control group is the vase with all water in it.

EXPERIMENTAL GROUP

• The experimental group is the vase filled with half water and half Sprite.

CONTROLLED VARIBLES

• The controlled variables are the same area, same vase, same batch of roses, same water used, and same sprite used.

DISCUSSION AND ANALYSIS

Through out this experiment, there have been many changes and results that surprised me. On day one, my mom got a bunch of twelve roses. She gave me four and put the rest in a huge vase. On day three, the roses my mom bought were dead! Another huge surprise came on day six and seven. On day six, the flowers were very still very white, but on day seven there was a huge change in the coloration. I think this happened because I refilled the vases everyday and put the roses in an area with a great amount of sunlight. A big challenge in this experiment was the time I picked to clean vases and take pictures of the roses. I unfortunately picked four p.m. which is the time I leave for soccer. So, I had to get ready quickly so I had time to clean and take pictures.

CONCLUSION

The hypothesis was if a vase is half filled with Sprite and half with water, then the flower will last longer because the Sprite will kill the germs in the water. The results of the experiment does support the hypothesis, because the flower in the experimental group did not brown as much as the control group, and the stem did not bend and die. The control group had much more browning going on in the bloom and the stem showed more signs of death. However both groups did very well looking lively the whole week due to daily cleaning. If this experiment was repeated, think about a good time to clean vases and take photos, and keep the flower in the same place after cleaning.
