 Students are testing for the presence of carbon dioxide in the air we exhale. |
 Students observed that the solution they breathed into changed colors. The color changed occured when an acid was produced because of the reaction of the solution to carbon dioxide |
 Students compare their control beaker to the tested solution. |
 The effect of carbon dioxide on bromothymol blue, a pH indicator. |
