• Can of Pepsi
• Can of Diet Pepsi
• Fish Tank or Large Container for Water
• Bag of Sugar

• Spoon
• Digital Scale or Triple Beam Balance

Density Fast Facts

• Denisty = Mass/Volume (d=m/v)
• Density of Water = 1.0 g/cm3
• 1 milliliter (ml) = 1 cubic centimer (cm3)
• Density greater than one sinks
• Density less than or equal to one floats
• Saturn is the only planet that would float if you placed it in water. It has a density of about 0.7 g/cm3

Handout

If you decide to perform this experiment with your class, you can use the following handout to have your students calculate the density of the two cans of soda.
