Engineering Design Challenge: Water Filtration

This web seminar featured background information about filtering water, both on Earth and aboard the International Space Station. During the seminar, teachers learned about the principles of water filtration and discovered how to incorporate that information into an exciting hands-on, inquiry-based challenge that requires students to design their own water filtration device. Participants watched a video showing students engaged in the challenge and received links to access supporting resources online.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NES is NASA's classroom-based gateway for middle school (grades 4-8) and high school (grades 9-12) classrooms providing authentic learning experiences inspired by NASA's unique missions. NES provides free teaching and learning resources that promote student engagement in science, technology, engineering, and mathematics, and opportunities for teachers and students to participate in NASA's mission of research and discovery through inquiry-based experiences directly related to the work of NASA scientists and engineers.
