Exothermic Reactions

Allow students to see how chemistry can be used in a beneficial manner. Most students are probably familiar with heat packs, or hand warmers. Utilizing the release of chemical energy, these self-contained exothermic reactions are quite useful in cold environments. In this activity, students will first investigate the temperature change of an exothermic reaction and then examine how the oxidation of iron, in a process similar to rusting, can be used to create the little bags of heat used to keep hands and feet warm.

The kit contains enough materials for 15 groups. Teacher's Manual and Student Study Guide copymasters are included.

Kit Includes:

  • 1 x 100g Calcium chloride
  • 15 Plastic cups

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
