Entropy, Energy, and Temperature
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 December 15, 2010 from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenter was Jerry A. Bell, retired member of the Education Division of the American Chemical Society (ACS), and he was assisted by Patricia Deibert and Bonnie Bloom. In this Seminar, Mr. Bell focused the discussion on the concept of entropy and its relationship to temperature.

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 four Web Seminars scheduled this fall in cooperation with the American Chemical Society. In this program, Mr. Bell presented information about entropy by leading people through observations and even hands-on activities that can be performed at home that demonstrate entropy relationships to temperature and energy. Mr. Bell also related the entropy information to the number of atom arrangements, as he had done in the previous program on entropy. Patricia Deibert and Bonnie Bloom assisted Mr. Bell on the chat by answering participant’s questions.

Thirty-four (34) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of California, Colorado, Georgia, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania, Tennessee, Texas, Virginia, Washington and Wisconsin. Three participants attended the Web Seminar from locations outside the United States: Germany, Northern Marianas 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:

  • “This was a great way of relating microstates of systems to the concept of entropy.”
  • “This seminar was a good method of explanation regarding enthalpy and entropy.”
  • “Finally helped me understand entropy and energy levels!”
  • “I can use much of what was discussed today to help describe the colligative properties better when I get to them in Advanced Chemistry.”

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