High-­school science teachers can radically reduce the cost of building up science labs while giving students opportunities to engage in genuine design processes by introducing them to open­-source hardware. A vast collection of free and pre­-designed low-­cost scientific tools are available, many of which can be printed on a open­-source 3­D printer, including the printer itself. Not only can students benefit from access to research grade equipment, there are ample opportunities for students to build on, improve, and customize scientific tools as part of their curriculum. In this way the number and value of the open­-source hardware designs can expand with student effort, enabling a powerful motivating factor for science education.

The Hiking Hack is the first of a proposed series of research expeditions investigating the role of situated design for wild animal interaction. This mobile workshop through the Panamanian Rainforest was designed to explore how context shapes the crafting of technology and to probe the limits of constructing and utilizing DIY physical computing systems in harsh environments. It also served as a means of engaging with and reflecting upon the biological, technological and cultural aspects interplaying in modern scientific research.
