If roses are put into a flower vase with just water then the rose will stay a little fresh because the flowers are made to flourish and stay fresh in normal water.
The controlled variables are the three roses in each flower vase, the 500 mL of liquid put into each flower vase and the same flower vase for both groups.
The experiment did not go as my family and I thought it would go. It took six days for noticeable changes to occur. The roses in the normal water or the orange soda water never had any change in scent. I was extremely surprised when I saw that the roses in the normal water died. The flowers in the experimental group always had a bit of bright red, there was never a time in the experiment that the roses in the control group turned dark magenta all over.
I was shocked when I saw that the flowers in water had completely died and the flowers in the mix of Orange Soda and water were okay. I think this happened because the Orange Soda had sugars and carbohydrates inside the soda and the flower would use those two things as a food source but the sugar in the Orange Soda is processed and the flowers in the experimental group had some dead petals and some alive petals.
The purpose of the experiment was to see if Orange Soda would help keep the freshness of a flower. The hypothesis was that if roses are put into a flower vase with just water then the rose will stay a little fresh because the flowers are made to flourish and stay fresh in normal water. In the end, the results of the experiment proved my hypothesis wrong because the flowers with normal water died on day 6 but the flowers in the Orange Soda and water stayed a little bit fresher.
In addition, the experimental group roses stayed fresher then the control group roses. The flowers in the control group died way faster than I thought they would die. Throughout the experiment the roses in the Orange Soda and water always looked better. Neither experimental or control group had any changes in scent. If the experiment were to be done again, someone could try to use a different brand of soda because different brands can have more or less sugars and carbohydrates.
