What Every Teacher Needs to Know – The Chemistry of Coffee

Grab a cup of joe—and get high school students’ excited about chemistry. This 10-lesson series created by high school educator Nate Talafuse, presents coffee from a chemical perspective. The lessons explore the chemistry of solutions, acids/bases and pH, the chemical compounds in coffee beans, the roasting process, and the art of coffee tasting, while also providing opportunities for students to use a temperature probe and timer (to observe how heat causes chemical reactions to occur, turning a “green” bean to dark) and a colorimeter (to determine the concentration of a solution—in this case, the pH of coffee—by analyzing its color intensity).
