This experiment was performed to find

out if the different brands of soda

can drinks have a higher density or

lower density than water. The

experiment was done to compare the

difference in densities between regular

Coke and Diet Coke.

The hypothesis is the regular and diet sodas will both sink in water.

In the chart is showed some comparisons in the characteristics of the different sodas.

The hypothesis is the regular and diet sodas will both sink in water.

Procedure

Fill the aquarium with water almost to the top.

Place a can of regular soda in water. This sinks.

Now place the diet soda in water. This doesn’t sink.

Why it works?

Cans of soda have exactly the same

volume and size. A regular soda is

sweetened with sugar, while a diet uses

any artificial sweeteners like

aspartame, you need only a few

grams to sweetena can of diet soda.

The difference in the amount of

sweeteners dissolved leads to a

difference in density: while regular

soda cans tend to be denser than

water and sinks, diet soft drink cans

are generally less dense than water

and float.
