Engineering in Practice for a Sustainable Future (EiP) is a GK-12, National Science Foundation (NSF) supported program (DGE-0538655) formed in partnership between the College of Engineering and the K20 Center at the University of Oklahoma. The EiP grant builds upon lessons learned from two previous NSF grants: The Authentic Teaching Alliance (ATA) and Adventure Engineering (AE).  EiP provides Fellowships to graduate students (Fellows) in science, technology, engineering, and mathematics (STEM) who are interested in K-12 outreach. EiP Fellows work closely with teachers and students in secondary classrooms and in summer academies to design, develop, and implement authentic, guided inquiry science activities and lessons that utilize the Engineering Method. Additionally, the EiP program has formed a partnership with the Prince of Songkla University in Hat Yai, Thailand to facilitate an Internatioal Engineering Academy, which closely models our Summer Engineering Academy.
