Science Buddies: Project Ideas: Explore the Chemistry Within Hand Warmers

Determine how the starting temperature affects crystal growth and heat generation of a hand warmer in this chemistry science fair project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
