Engineering Design Challenge: Water Filtration

This Web Seminar took place on November 3, 2011, from 6:30 p.m. to 8:00 p.m. Eastern Time. Presenting was Kristy Hill, an education specialist at Marshall Space Flight Center. In this Seminar, Ms. Hill talked about the need that life has for water and ways that water gets recycled on Earth, in cities and in the International Space Station. She also shared lessons from the Water Filtration Challenge guide.

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 is the first presentation of Engineering Design Challenge: Water Filtration and it will be repeated during this academic year. Ms. Hill shared a number of videos showing elements of the lessons that can be found in the Water Filtration Challenge guide, as well as others showing how water is filtered on the International Space Station. Ms. Hill walked the audience through some of the lessons in the guide and talked about necessary materials. She also shared information to help teachers implement these lessons in the classroom.


Thirty-three (33) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of Arizona, California, Florida, Illinois, Maryland, Massachusetts, Minnesota, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Texas, Virginia and Washington. In addition, one participant joined the program from a location outside the United States: Israel.


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:

  • "Teaching students about recycling water, about technology permitting humans to live in space, and engaging students in designing such technology are prime goals of my teaching."
  • "We make this sort of filter in summer environmental science - the videos will be a great help as well as the how to on the multi-meter based conduction meter."
  • "This content on water will be useful to augment our discussion on the water cycle, part of our NC 5th grade tested content."
  • "I was glad to see more about how to make a water filtration system and a water filtration lesson plan."

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