QUESTION

HYPOTHESIS

• If rubbing alcohol is put into a rose's vase, then the rose will last longer because the chemicals in the alcohol with eliminate any harmful bacteria.

MATERIALS

• 4 identical roses
• Two identical vases or pots
• A planner
• A camera
• An iPad to create a detailed report
• Rubbing alcohol
• Pencil
• Water

PROCEDURE PART 1

• Acquire 4 identical roses
• Obtain 2 identical vases labeled "experimental" and "control" and pour 1 liter in each of them
• Put two roses in each of the vases
• Pour 1 teaspoon of rubbing alcohol in the vase labeled "experimental" and pour 1 teaspoon of water in the vase labeled "control"
• Place both jars on the same table with the same amount of sunlight
• Repeat step 5 every other day until data collection period has ended

PROCEDURE PART 2

• Take a camera and take a picture of the flowers
• Repeat step 1 every day at 7:00 AM and at 7:00 PM
• Devise a set of specific observations such as: leaf texture, petal texture, water color, stem color, number of petals wilted, number of leaves fallen off, etc.
• At 7:00 PM, use your pictures to create a set of detailed observations
• Create a detailed report using your data

CONTROLS AND VARIABLES

• Independent variable is the alcohol
• Dependent variable is leaf and petal texture/stem, water, and petal color
• Control Group is the vase of flowers that wasn't administered with alcohol
• Experimental Group is the vase that was administered with alcohol
• Controlled Variables: same amount of water, same number of flowers in each group, same amount of sunlight, same amount of added liquid, same time period, same observations

DATA ANALYSIS

MAJOR CHANGES/RESULTS

• The control group flowers started drooping much faster than the experimental group.
• Experimental group stayed fresh much longer than the control group and had a better result as well.
• It was not expected to control group to wilt so quickly, and it also wasn't expected that the experimental group would last so much longer than the control group

QUANTITATIVE CHARTS

LEAVES FALLEN

PETALS WILTED

CONCLUSION

• The hypothesis was that if rubbing alcohol was added to the water of a vase of 2 flowers, then the lifetime of both roses would be elevated because the chemicals in the alcohol would eliminate any harmful bacteria that could get into the water. Based on my observations, rubbing alcohol appears to have a profound effect on a rose's lifetime and supports the hypothesis because the experimental group's flowers styled straight for 3 days longer than the control group.

FURTHER EXPERIMENTING

• If another experiment were initiated, to vary the experiments, the variable to change would be the amount of water in each vase because the effect of the alcohol could have a more profound effect on a larger body of water than on smaller one.
