A Carolina Exclusive! Grades 9-12. Students discover how chemical and physical changes can absorb and release heat energy. After measuring the heat of combustion for a common fuel and the heats of solution for some common salts, students design a hot pack and a cold pack that could be used as a portable first-aid device. Part of the Inquiries in Science® series. Materials are sufficient for 30 students working in groups of 3.

• Differentiate between heat and temperature
• Calculate heats of reaction from standard heats of formation
• Design a hot pack and cold pack
