The Periodic Table and Bonding — Introducing a Free Online Resource for Middle School Chemistry

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 January 17, 2013, from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenter was James Kessler, Manager of K–8 Science Education at the American Chemical Society. In this seminar Mr. Kessler shared lessons and activities from the fourth chapter of middleschoolchemistry.com, a web-based resource that helps teachers engage middle school students with chemistry concepts.

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 fourth presentation in a series of six web seminars covering each of the six chapters in middleschoolchemistry.com. Mr. Kessler began the presentation with a tour of the website then provided a detailed look at the lessons featured in chapter 4. He shared activity ideas and multimedia clips that can help students learn about the periodic table and atomic bonding. Participants discussed the application of the lessons to their own classrooms and shared ideas for modifications and extensions.


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:

  • “Great resource, it is certainly something that I will be able to use with my 9th grade physical science and even my lower level 11th grade chemistry students.”
  • “I enjoyed learning about middleschoolchemistry.com, a website that I have never used (but will use now).”
  • “I especially liked seeing the video connections to the lessons.”

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