Bottles of soda are sealed under high pressures of CO₂, or P_CO2. This causes a substantial amount of CO₂ to dissolve into the beverage, giving the drink its fizziness. But what exactly is the pressure inside a bottle of soda?

I previously "NGSS-ified" one of my favorite inquiry labs to begin the kinetics unit; Alka Seltzer Rockets. In this lab students are given a film canister, a quantity of Alka Seltzer of their own choosing and any materials available in the room to investigate factors that affect the rate of reaction.
