Chemical Change – 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 May 20, 2013, from 6:30 p.m. to 8:00 p.m. eastern daylight 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 sixth 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 sixth 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 6. He shared activity ideas and multimedia clips that can help students learn about chemical reactions and discover what’s happening on a molecular level to change reactants into products. Participants discussed the application of the lessons to their own classrooms and shared ideas for modifications and extensions. Patti Galvan from the American Chemical Society helped out by answering participant questions on the chat.


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 really enjoyed the video clips and the explanation of each chemical reaction. It was very clear exactly what was happening and inferences the students should be making from each.”
  • “This one was one of the best I've attended. So many hands on activities, so much teacher support, how to get and use the supplies, the animations are fantastic... perfect.”

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