Xplore Engineering is an outreach event designed for alumni and the children in their life entering the 4th through 7th grade. Through a series of experiential workshops, participants get hands-on experience in a variety of engineering disciplines.

Through the materials science department, Peter helped run the eXtraordinary Materials workshop where kids got to investigate the structure of common materials through optical and electron microscopy and learn about how materials can behave unexpectedly at really hot or really cold temperatures. Demos included heating a space shuttle tile with a blowtorch, heating an iron wire and observing the high temperature phase change, and cooling rubber through the glass transition temperature with liquid nitrogen so it becomes more brittle and eventually shatters.
