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.

Four different kinds of pop (2 liter bottles)

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. The hydrometer is accurately calibrated when it floats i

4. Add 25g of sugar to the water. This is ten percent of the solution. Stir the sugar in the water until it is completely dissolved. Mark the water line on the pipette and label this the ten percent line. Continue this process adding 25g of sugar each time therefore increasing the sugar content of the solution by ten percent. When finished there should be zero, ten, twenty, and thirty percent markings.

This lab was designed to measure the sugar content in pop using a hydrometer. A hydrometer measures density of a liquid, so using it would be a great way to find the sugar content of different pops. The results displayed that Diet Coke had no sugar at all therefore being the best for your teeth. Sprite had the least amount of sugar, however Sprite, Coke, and Cherry Coke all had very similar amounts of sugar with not a lot of variance. The results lead us to believe that Diet Coke was the slowest when concerning tooth decay while the others differed very little, but still contained around 10% sugar.

1. Find the average percentage of sugar in each kind of pop using the five trials in the data table.
