We do a unit on chemical reactions and energy. The anchoring phenomenon is how an MRE flameless heater works. We introduce them to MREs and their heaters and when you might use them. Power outages due to storms, etc. I mention that example because many were in their cars for 8-12 hours. IF they had an MRE in their car's emergency kit they could enjoy a warm meal of roasted rat while they waited it out.
The unit itself focuses on Sandy and Maria but I throw in tht storm, the 2008 ice storm, and the flooding from 2023 because I'm a weenie
