Science Fair Lab Report
Abstract
The objective of this science fair project is to determine the effectiveness of using sugar to preserve and keep the flowers fresh for longer periods of time. The experiment will be carried out using flowers such as the pompons, alstroemeria, sunflowers and water containing different amounts of sugar
Hypothesis
Flowers that are in contact with a more concentrated sugar solution will be able to last longer.
Background
Keeping flowers fresh "Beautiful" and "sweet-smelling" are two common terms that describe fresh flowers, and explains why so many of us like to place flowers in our homes. Having flowers in our homes adds color and a soft touch. In addition, the presence and scent of flowers gives us a psychological boost …show more content…
The independent variable in this science fair project is the species of flower (pompons, alstroemeria or sunflower) and the amount of sugar added to the water (none, 1 teaspoon, 2 teaspoons or 3 teaspoons). The dependent variable is the number of days the flowers will remain fresh. This is determined by observing the flowers everyday for signs of wilting. The constants (control variables) are the size of the vase, the amount of distilled water in the vase and the room temperature. 2. Cut the stems of the pompons, alstroemeria and sunflowers in a slanted angle using the scissors provided. Fill the 12 vases with equal amounts of distilled water. Label three vases each as 0, 1, 2 and 3. The three sets of vases correspond to the three species of flowers. Place one stalk of each type of flower inside the vases labeled as 0, 1, 2 and 3. Add one teaspoon of sugar to the vases labeled 1, two teaspoons of sugar into the vases labeled 2, and 3 teaspoons of sugar into the vases labeled 3. Do not add sugar into the vase labeled 0. Add 3 drops of vinegar into all 12 vases. 4. Observe the 12 vases daily and note the number of days during which the flowers remained fresh. Record the results in the table …show more content…
Conclusion
The experimental results are in accordance with the hypothesis that fresh-cut flowers are able to last longer when placed in solutions of sugar of higher concentration - but only up to a certain optimum level. Besides adding nutrition (eg. sugar/flower food) to the water, the flowers should be kept in a cool place away from fruits. The water should also be changed every two days to prevent bacteria buildup.
Also consider
What would happen if this science fair project were to be repeated using different additives in the water such as commercial plant food or aspirin? The experiment can also be done using different types of flowers like roses or daffodils?
