            This experiment was more interesting and more applicable than my science fair projects in the past. Now I know the exact pH levels in my foods and other things. The different colors that the indicators made were extremely fascinating, despite the permeating stink of Windex and Clorox bleach.

            The experiment was fairly successful. A pH color scale for each effective indicator was established and used to discover the pH levels for many household items. The pH level estimations for vinegar, lemon juice, orange juice, grapefruit juice, egg whites, baking soda, bleach, Windex, and Sprite were all determined. If someone wanted to find the effects of household items based on pH , they could easily find them based on the results from the experiment. Only one item, bleach, was entirely impossible to find a relative pH level for.

            Natural indicators are by no means the most accurate way to determine pH, but they do serve the purpose for a home environment. Part C of the lab is safe for even little kids to conduct, and the color changes will fascinate them.

            To achieve more accurate results, several trials for both Part B and C could be conducted, and a wider variety of indicators could be used. Other good indicators include red beets, hydrangeas, strawberries, and hollyhocks. Other household items to test include antacid tablets, aspirin, soaps, any type of fruit juice, any carbonated drink, shampoo, floor wax, carpet cleaner, laundry detergent, and all household cleaners.
