Surface area is known to be beneficial to keeping organisms alive it allows huge organs such as the intestines to fit in a small area by being coiled and packed together tightly. This experiment looked if the surface area to volume ratio affected the speed of a chemical reaction. For this experiment, a film container was filled one-half full with water. Then an Alka-Seltzer tablet was added, quickly covered with a cap and was observed until the film cap popped off.
