Product Details

The Flameless Ration Heater is most commonly used by the U.S. military to heat food pouches called Meals—Ready to Eat. This ration heater not only allows soldiers to eat a hot meal in the field but also aids in the relief of victims of natural disasters. Learn how the super-corrosion of magnesium produces enough heat to warm a meal in 15 minutes and keep it warm for up to an hour. Detailed teacher notes included.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-6. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
MS-PS3-3. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
