Engineering Design Challenge: Water Filtration

This Web Seminar took place on March 13, 2012 from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenter was Kristy Hill, NASA Explorer Schools Education Specialist at Marshall Space Flight Center. In this Seminar, Ms. Hill described a hands-on activity that challenges students to design a water filtration device similar to the system used to recycle water on the International Space Station.

The PowerPoint, related resources from the NSTA Learning Center, and web links from the presentation are now contained in the above resource collection. Clicking on the collection link will place it in your Learning Center, My Library, neatly organized under the My Resource Collections tab.

This was the second and final presentation of Engineering Design Challenge: Water Filtration for the 2011-2012 school year. In the seminar, Ms. Hill discussed the ways water is recycled by nature, municipalities, and NASA in space. She talked about the need for sophisticated water filtration systems on-board the International Space Station in order to reduce the amount of fresh water brought from Earth. Ms. Hill also shared details about implementing the engineering design challenge in class, including materials and equipment, concepts students will learn, and extension activities.

Fifty-five (55) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of Alabama, Arizona, California, Colorado, Connecticut, Idaho, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, Minnesota, New Jersey, New York, Ohio, Oklahoma, Oregon, Pennsylvania, Tennessee, Texas, and Wisconsin. In addition, four participants joined the presentation from locations outside of the United States: Germany, Philippines, and Turkey.

Seminar participants received one of the NSTA SciGuides. A certificate of attendance was deposited into participants' My PD Record and Certificates area in the NSTA Learning Center for completing the evaluation form at the end of the program.

Here are some comments provided by the participants at the end of the Web Seminar:

  • “Great lesson to do with students to help them build inquiry skills as well as to help them understand engineering and design processes.”
  • “The videos were helpful. I am excited to try this one with my students.”
  • “Great seminar. I think the engineering design challenge[s] are great hands-on learning for students.”
  • “As a student teacher this gives me great ideas for the classroom.”

Thanks to the participants and the presenter for the learning opportunity, the interactions, and a job well done!
