Investigating the field of engineering offers the opportunity for interdisciplinary, hands-on, inquiry-based units that integrate real-world applications; yet, many K-12 students are not exposed to engineering until they enter college. Get a Grip! is a problem-based unit that places middle school students in the role of engineers who are challenged to design and construct prosthetic arms for amputees in a war-torn country. The students use common materials to build arms that accomplish tasks requiring fine motor control and strength.
