Research Education and Activities for Classroom Teachers is an event where grade school teachers from around Michigan can come and attend workshops to participate in materials science labs that they can then take back to their respective classrooms. Peter helped develop and run the “Introduction to Composite Materials” demo at REACT, where students (teachers) made their own composite concrete mixtures and tested the mechanical properties. The goal of the lab is to get students thinking about how different reinforcement materials can impart different properties into the composites and about how to optimize a material for a given application.
