Just add chunks of dry ice to various acid–base indicator solutions and observe the brilliant color changes. Teach students about sublimation and other properties of dry ice. Discuss pH and acid–base indicators. Write the chemical equation for the formation of acid from the dry ice. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.

Time Required: 10 minutes
Chemicals Provided: Ammonia solution and indicator solutions of bromcresol green, bromthymol blue, methyl red, phenol red, and universal indicator.
