For teachers
Turn everyday objects into manufacturing conversations.
A pen, bike part, phone case, medical implant, guitar bridge, aircraft bracket, and food package can all open a discussion about material, process, tolerance, quality, cost, safety, and careers.
Classroom prompts

Map one local employer to the skills it needs.
