**Erika R.** **2011-2012**  The purpose of these experiments was to see and find the different acidity levels in different acidic fruits. In the introduction, it states what an acid is, what a pH scale is, what fruits are, the difference between an organic fruit and a non-organic fruit is, why people prefer organic fruits to non-organic fruits, and what Brown did in a project before. In the method, it states what was done for the first, second, third, and fourth experiment which was to find the acidity levels in canned and organic grapefruits and oranges, find the acidity when different amounts of grapefruit juice were added to water, find the acidity levels in organic grapefruits, oranges, lemons, and limes, and find the different acidity levels in different liquids being orange, lemon, and lime juice and orange, lemon, and lime popsicle juice. The results for the first experiment were that organic grapefruit had the most acidity, the results for the first follow up experiment were that the acidity increased each time more grapefruit juice was added, the results for the second follow up experiment were that lime had the most acidity, and the results for the third follow up experiment were that lime still had the most acidity out of popsicle juice and organic juice. In the discussion, the results were talked about and any trends that were seen.
 * THE STUDY OF THE DIFFERENT ACIDITY LEVELS IN CANNED FRUIT AND ORGANIC FRUIT **
 * ABSTRACT **


 * CONCLUSION **

The results for the first experiment were that organic grapefruit had the most acidity, the results for the first follow up experiment were that the acidity increased each time more grapefruit juice was added, the results for the second follow up experiment were that lime had the most acidity, and the results for the third follow up experiment were that lime still had the most acidity out of popsicle juice and organic juice. This data is important because now people can see the acidity levels in the specific fruits that were tested and see if more acidity or less acidity helps the human body and why. The hypothesis that was predicted was correct, that grapefruit would have the most acidity out of organic and canned grapefruits and oranges because grapefruits are produced with more acid than oranges. Some experiments that can be done in the future are to see if different types of acidic fruits affect one’s strength.
