=Determining the Acidity of Different Types of Candy= Emily K. 2012- 2013

ABSTRACT:
The experiment’s purpose was to find which candy was the most acidic and worst for your teeth, or which candy had the lowest pH (acidity level). The experiment was to have each candy crushed and placed in 80 mL of tap water. Then, the pH was taken with a pH probe. Taste test were conducted on Sweetarts, M&M’s, Skittles, Baby Bottle Pop Powder, Jolly Ranchers, and Candy Hearts. The hypothesis (based on a taste test of the different types of candies) was that the baby bottle pop powder would be the most acidic because it was the sourest. After testing each of the candy’s pH, it was found that the baby bottle pop powder had the lowest pH at a pH level of 2.12. Additional experiments were conducted including taste tests of different colors of Sweetarts, and the blue Sweetarts were the most acidic. The baby bottle pop powder is the worst for your teeth, therefore confirming the hypothesis.

EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS:
This experiment could be improved by making it more interesting by testing the acidity of more candies, and other foods such as soda or fruit. It could also be improved by testing the effect of the candy water mixture on teeth. Teeth could be used and put in different candy mixtures to see the effect of teeth.
