Soda And Effects On Teeth Sweet Tooth Background: During the 1970’s, teenagers drank twice as much milk as soda pop. Since then, the statistics have reversed, having a direct relation to tooth decay. Human teeth were not made to withstand that type of daily exposure to soda. Plaque or bacteria, establish an active colony in the mouth then convert sugar in the beverages to acid. This acid is responsible for breaking down tooth enamel and causing cavities. Purpose: The purpose of the lab is to determine which pop has the least amount of sugar, therefore decreasing tooth decay. This is done using a hydrometer. Materials: Pipette Metal BBs Scissors Permanent marker Distilled water Sugar Stirring Rod Four 400 mL beakers Four different kinds of pop (2 liter bottles) Procedure: 1. Use four 400 mL beakers and fill them with 250 mL of the four different types of pop. Let them sit for a day in order to make sure the pop becomes flat. 2. Fill a 400 mL beaker with 250 mL of distilled water. Obtain a pipette and metal BBs. Cut the tip off the pipette so it is big enough for it to be filled with BBs. Calibrate the hydrometer by adding or removing BBs from the pipette. soda, teeth, sugar, pop, hydrometer, coke, trial, content, percent, water, lab, data, pipette, ml, using, tooth, results, percentage, line, four, diet, completely, therefore, ten, take, table, substance, flat, five, dissolved, different, decay, best, beaker, bbs, zero
