The document summarizes the design and development of an online micro-module on sustainability for City University. It outlines the project brief to develop content on sustainability provided by the Centre for Food Policy. It then describes the research conducted, including on existing interactive applications, understanding sustainability, competitor analysis, and student workshops. Different concept designs and prototypes were created and evaluated, including a 3-part journey prototype and a historical narrative prototype.
