Abstract:
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.
Procedure preview:
1.    For this experiment, the independent variable is the density of the regular coke and diet coke. The dependent variable is whether the can will float or sink in water. This is determined by observing the cans after they are placed in the water. The constants (control variables) are the density of the water, the temperature of the water and volume of the tank. 2.    The water tank is filled with 5 liters of water. The depth of the water in the tank must be at least 150mm. 3.    The cans of regular coke and diet coke  are  placed in .....
