The Water Molecule and Dissolving - 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 March 18, 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 fifth 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 fifth 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 5. He shared activity ideas and multimedia clips that can help students learn about the water molecule and dissolving. 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:

  • “I learned that I can challenge my students more with interesting experiments (inquiry labs) that I had not thought of doing and had never read about.”
  • “Thank you for the resources. This will be a big help to my teaching.”
  • “I love the animations--one of the hardest things to make/find for illustrating concepts to students.”

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