Classroom repairs

Classroom repairs

The Classroom Repairs project introduces students to sustainability and product obsolescence issues. Students are to consider the sustainability of products in their environment. Then they identify and produce repairs for the classroom. The project is intended as a single lesson with printing after the session. The project can be extended to a second lesson, if needed, by testing the printed designs and suggesting future improvements.
