This actvity focuses on allowing students to explore how stored energy can be converted into kinetic energy, using demonstrations of example systems and hands‐on activities with simple engines. Students interact with low temperature Stirling engines that can be powered from body heat and explore how heat can be used to create mechanical energy. A demonstration illustrates how a small cart can be powered by a candle. A task challenges the students to build a working steam powered top, powered by a candle to produce circular motion. Students also learn about fossil fuels and energy sources.
