This paper describes the makerspace challenge, an experiential assignment that builds foundational entrepreneurial competencies through the creation of artifacts within campus makerspaces. This assignment strengthens student ability to navigate ambiguity, learn new technologies, effectively utilize resources, and bring creative ideas to reality in a low stakes supportive environment. Students choose 3 out of 4 pre-identified projects to complete outside of class over a three week period, presenting a tangible artifact in-class each week. Grounded in constructionist pedagogy, this assignment is particularly appropriate for introductory entrepreneurship courses, but can easily be scaffolded to be applicable throughout the entrepreneurship curriculum.
