This experiment will examine and precisely measure the amount of sugar in various sodas. -What is the percentage of sugar in different kinds of soda? -Do all sodas have the same sugar content? We all know that sugar is filled with soda, but it’s hard to see just how much is in our drink by simply reading the label. Using a scientific instrument called a hydrometer, you can find out by precisely measuring the sugar content. Technically, a hydrometer measures any solids in a liquid, but since nearly all the dissolved solids in soda is sugar, it will work for this experiment.

You know regular soft drinks supposedly contain a lot of sugar. Most of the sugar takes the form of sucrose (table sugar) or fructose. You can read the side of a can or bottle and see how many grams there are, but do you have any sense of how much that is? How much sugar do you think is in a soft drink? Here's a simple science experiment to see how much sugar there is and learn about density. Not to ruin the experiment for you, but your data will be more interesting if you compare different types of soft drinks rather than different brands of the same thing (e.g., three types of cola). This is because the formulations from one brand to another vary only slightly. Just because a drink tastes sweet might not mean it contains the most sugar. Let's find out. Here's what you need:
It's an experiment, so use the scientific method. You already have background research into sodas. You know how they taste and may even have a sense of which tastes like it contains more sugar than another. So, make a prediction.
The numbers you recorded were your data. The graph represents the results of your experiment. Compare the results in the graph with your predictions about which soft drink had the most sugar. Were you surprised?
