Background: Alka-Seltzer tablets fizz furiously when dropped in water. The moment the tablets start dissolving, a chemical reaction occurs which releases carbon dioxide gas at a predictable rate.
In these 4 mini experiments, students will use the steps of the scientific method to see if they can make Alka-Seltzer fizz faster or slower by changing variables such as type of water, amount of water, temperature of the water, and by grinding up the tablet!
