Solving the Smog Puzzle on Earth and from Space: Good vs. Bad Ozone
All web seminar participants use online tools that allow them to mark-up presenter's slides or share desktop applications in addition to engaging in chat with others online and answering poll questions

This web seminar took place on April 1, 2013, from 6:30 p.m. to 8:00 p.m. eastern daylight time. The presenters were Michael Tinnesand, an educational consultant with the American Chemical Society; Ginger Butcher, education lead for NASA’s Aura mission; and Bryan Duncan, deputy project scientist for NASA’s Aura mission. In this program the presenters traced the story of scientists’ discovery of pollutants in our atmosphere and shared ideas for incorporating this and other chemical stories into the high school chemistry curriculum.

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.


During this web seminar the presenters told the story of the puzzling smug that descended over Los Angeles in the 1940s and the research that scientists began conducting on the chemical makeup of atmospheric pollutants. The presenters talked about discoveries made in the 1970s that revealed that everyday products were contributing to catastrophic chemical reactions high in the atmosphere. Participants viewed video clips, checked their knowledge with poll questions, and learned about lab activities to use with students.


This web seminar was another in a series designed to provide secondary teachers insights into presenting often difficult chemistry concepts in the context of everyday experiences students can relate to. These seminars are sponsored by the American Chemical Society (ACS) Education Division, Office of High School Chemistry. For more information about ACS resources for high school teachers, please visit www.acs.org/highschool.


Seminar participants received an NSTA SciGuide. 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:

  • "I enjoyed the way the presenters made everything relevant and usable for next day teaching!"
  • "Great resources! Excellent presenters! Very good slides and videos!"

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