Overview

Students will perform two different experiments where they are asked to record the overall mass of the reactants and products before and after the reactions takes place. Both experiments will be "closed system" experiments where any gases produced will be trapped by either parafilm or a balloon. Students should observe that overall mass should remain the same before and after each experiment leading them to the law of conservation of mass. This proves that a carbonated beverage can be produced via a chemical reaction.
