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. They complete 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 will use the engineering design process to create their own homemade heater.
