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. NASA Explorer Schools invests in science, technology, engineering, and mathematics educators to inspire and engage a whole generation of future scientists, engineers and technicians that NASA needs to continue our journey. NES gives educators of grades 4-12 free access to NASA's people, missions, research, and facilities. We take the work out of searching through thousands of materials on the NASA website and provide a comprehensive set of teaching materials for dozens of STEM concepts.
