AACT provides a variety of ways in which K12 teachers can share a broad selection of chemistry lessons and activities.  Teachers can search for lessons and activities to illustrate chemistry topics suitable for all grade levels.  One activity that I submitted involves demonstrating the temperature dependence of the solubility of gases in water utilizing Alka-Seltzer tablets.  Students explore the solubility of CO<sub>2</sub> in water using bromothymol blue indicator to determine the pH of the solutions, conducting semi-quantitative titrations of solutions prepared by dissolving Alka-Seltzer tablets in warm and cold water.  In this manner, one activity easily conducted in one classroom period, utilizing generally available and safe materials, illustrates the topics of solubility, intermolecular forces, acid-base chemistry, indicators, and titrations.<br/>
