As schools tighten their budgets and focus more and more on Academic Standards, public gardens can collaborate instead of compete with other local cultural institutions to create innovative cross-disciplinary student learning opportunities. This session will examine how four gardens of diverse size and geography have approached organizing and funding both small and large multi-institutional S.T.E.M. and S.T.E.A.M. collaborations. There will be a unique opportunity to hear directly from funders of the Minnesota collaboration regarding their motivations for giving, suggesting how similar visionary donors might be engaged in other regions. This presentation will focus on the how's and why's of curriculum development and funding and reveal the staff time and logistical infrastructure needed to successfully administer these collaborations.
