The integrated STEM inquiry featured in vignette 5 was planned as a user-centric STEM activity on bettering the lives of rubber tappers through improving the design of latex storage containers. The overarching goal of the STEM challenge was closely tied to the major economic and health concern of how the daily work of rubber tappers in the community can be made less stressful or laborious. Unique to this activity was the presence of expert voices to give students authoritative feedback and hold them accountable for their ideas and designs.
