Students use a calorimeter made of common materials to demonstrate that energy can be measured and converted from one form to another. Hydrocarbons, such as paraffin, contain stored chemical energy; food contains stored chemical energy. The activity uses a raw potato, a nut, a candle, an aluminum drink can, a thermometer, and a balance scale. A data sheet is included in the resource. The investigation supports material presented in chapter 1, "What is Energy?" in the textbook, Energy Flow, part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.
