Sacramento is the home of Solar Cookers International, a longstanding research and advocacy organization that has been disseminating designs and practices for solar cooking. EnergyTeachers.org is a network of educators interested in energy production and use, started by physics teachers. Workshop participants will learn about how SCI researches and teaches about solar cookers and how educators from EnergyTeachers.org have been teaching physics with the cookers. Participants will build a cooker, use electronic sensors, cook something in the sun, and take the cookers and sensors home. Activities and concepts will include data-logging, digital and analog, automatic and manual; selective materials, examined in multiple wavelengths; infrared thermography; heat capacity; power; engineering design; pasteurization; replacing cooking fuels; diverse cooking methods for diverse situations; curriculum scope and sequence; and attitudes about women’s work and about engineering to 'save the world.'
