Chemical Bonding: Learning From “Simple” Models
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 October 13, 2011 from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenters were Jerry A. Bell, retired member of the Education Division of the American Chemical Society (ACS), and Bonnie Bloom, chemistry teacher at Hilliard Davidson High School in Ohio. In this Seminar, Mr. Bell and Ms. Bloom talked about ways to model chemical bonds and molecular geometry.

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 fourth of five Web Seminars scheduled this fall in cooperation with the American Chemical Society. In this program, Mr. Bell and Ms. Bloom talked about ways to model atomic bonds and molecular geometry using balloons. The presenters answered many questions and participants engaged in a lively pedagogical discussion about different approaches to teaching bonding and molecular geometry.


One hundred six (106) 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, Connecticut, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Virginia, Washington and Wisconsin. Four participants attended the Web Seminar from locations outside the United States: Dominican Republic, Mexico, Nicaragua, Puerto Rico 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:

  • “Having the lone pairs and bonding pairs be different colors of balloons for the model of water was a new idea.”
  • “I am always looking for meaningful ways to model properties. I think balloons do a good job with this concept.”
  • “I think that I will be able to use the balloons as an effective review technique for my 2nd year AP Chem. students. They did cover this material in Honors Chem., but I think not only will the visualization spark their memories more quickly than simple discussion, BUT it will also spotlight those misinterpretations that are still lingering in their minds.”
  • “The content will assist me in teaching students about the bonding of atoms.”

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