Check out Kate Fletcher and Mathilda Tham's project 'lifetime.' This project would serve as an inspiring resource and reference to incorporate into your design curriculum. The project investigates 'Clothing Rhythms' and 'Design Scenarios' through a very specific context:
"This project is about the rhythms of time, ecological thinking and the design and use of fashion clothes for women. It is motivated both by necessity and opportunity. Necessity arising out of the increasingly urgent need to embrace more sustainable patterns of production and consumption; and opportunity, of the massive creative potential of working with people, environment and products."

Be sure to check it out, as it could inspire your students to understand the ecological and social impact of designs, and understand the potential to create new scenarios, and new rhythms.
