Abstract
Short-season high-altitude environments present significant challenges for home food production and school gardening. To address the need for local self-reliance and season extension in Idaho’s Wood River Valley, University of Idaho (UI) Extension educator initiated a program to teach geodesic dome greenhouse construction. The objective was to test a specific DIY design for structural viability in harsh winters while fostering community partnerships and enhancing K-5 STEM (Science, Technology, Engineering, and Math) education. The methodology involved a cross-state collaboration with University of Wyoming Extension to adapt an existing construction manual for local material availability. Using a $3,000 UI Extension Innovative Projects grant, the educator led a team of Extension staff and school volunteers to construct a 16-foot diameter trial dome at Hailey Elementary School. This "pilot" build served as hands-on training for the educator and a proof-of-concept for the community. Results demonstrated that the geodesic design, featuring gas-chamber-triggered automatic venting and a snow-shedding geometry, is highly effective for the region’s climate. The project created a permanent outdoor classroom for 450 students, where art and engineering teachers now integrate greenhouse-based curriculum, such as calculating volume for planter boxes and studying plant physiology. Since completion, the dome has served as a high-visibility "showpiece," resulting in significant community inquiry and a waiting list for future builder workshops. It is concluded that the geodesic dome greenhouse is a viable, cost-effective solution for high-altitude season extension. Furthermore, donating the trial structure to a public school maximized the Extension program's visibility and established a long-term venue for youth agricultural literacy.
