In this activity, students devise ways to demonstrate that energy can change from one form to another in accord with the law of conservation of energy. Small appliances, toys, marbles, vinegar and baking soda, simple electrical supplies available from a hardware store, and thermometers are needed to complete this activity. A student worksheet and an assessment rubric are included with 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.
