Explore the chemistry of flameless ration heaters (FRH) with this 6-activity demonstration kit. Students observe the physical and chemical properties of FRH components and, together with the observed corrosion reaction, use this information to identify the reactants and products for a balanced FRH reaction. Great activity for teaching chemical reactions or as an introduction to thermochemistry. Extension activities are included. Materials are sufficient for the 6 demos to be performed 5 times.

• Learn about the Flameless Ration Heaters (FRH) used in Meals Ready to Eat (MREs), camping supplies, and survival gear.
• Observe physical and chemical properties to identify FRH components.
• Use NGSS practices of Analyzing and Interpreting Data and Constructing Explanations and Designing Solutions.

Explore the chemistry of flameless ration heaters (FRH) with this 6-activity demonstration kit. Disassemble an FRH and demonstrate the physical properties of its components. Collect the gas evolved from a micro version of the FRH reaction to identify 1 of the products of this reaction. Test the pH to help identify another of the products. Test the identity of the salt used to accelerate the FRH reaction via a precipitation reaction. Use a flame test to identify the metals in the FRH. Finally, demonstrate the dramatic temperature increase inside an activated FRH. Students use the data and observations gathered during these demos to identify the reactants and products of this corrosion reaction and write a balanced equation for the FRH reaction. Great activity for teaching chemical reactions or as an introduction to thermochemistry. Extension activity ideas are included. Materials are sufficient for the 6 demos to be performed 5 times.
