In this 21-day unit, students are introduced to the anchoring phenomenon—a flameless heater in a Meal, Ready-to-Eat (MRE) that provides hot food to people by just adding water. Students explore the inside of an MRE flameless heater, then do investigations to collect evidence to support the idea that this heater and another type of flameless heater are undergoing chemical reactions as they get warm. Students have an opportunity to reflect on the engineering design process, defining stakeholders, and refining the criteria and constraints for the design solution.

In this unit designed for an integrated middle school science classroom, students investigate why athletes ice injuries. This leads students to wonder why actual bags of ice are used instead of the instant ice packs found in first aid kits. Students then investigate the chemical reaction occurring within an instant ice pack and work to develop a better design.
Anchoring Phenomenon: First aid care for musculoskeletal injuries using bags of ice instead of instant ice packs containing an endothermic chemical reaction.
