This online course features a series of seven challenges that engage students in the positive power of engineering and human-centered design. Lessons are designed to make it easy for grade 4-8 teachers to deliver remotely and include instruction as well as videos that can be assigned directly to students. Centered on the work e-NABLE has done to bring 3D printed prosthetics to people all around the world, students will learn about the Engineering Design Process, how makers and engineers are using that process in the face of COVID-19, the power of empathy in design, anatomy, and simple machines. The culminating challenge gives students the opportunity to create an initial prototype of an upper limb prosthetic.
