Building a Better Hand Warmer

Students use a temperature sensor to determine the heat of solution of a number of ionic compounds and propose a practical hand warmer design.

This lab incorporates principles of thermochemistry and engineering in the proposed creation of a viable product. Students are expected to use thermodynamic data, material cost and knowledge of chemical toxicity to propose a design for a commercially producible hand warmer.

Featured Equipment

Calorimetry Cups (6)

Set of six polystyrene calorimeter cups for beginning calorimetry.

Wireless Temperature Sensor

The Wireless Temperature Sensor is a general-purpose sensor found in many science labs. With a rugged, waterproof design and a long-lasting battery, students can spend more time collecting data and less time dealing with equipment.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
