Entropy: Mixing and Oil Spills
This Web Seminar took place on November 23, 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).
He was assisted by
and Bonnie Bloom. In this Seminar, Mr. Bell discussed the concept of entropy and
how it relates to mixing.
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 third of four Web Seminars scheduled this fall in cooperation with the American Chemical Society. In this program, Mr. Bell illustrated how substances mix and demonstrated how to calculate the mixing relationships. He also talked about water-oil mixtures and showed how this information applies to oil spills. Patricia Deibert and Bonnie Bloom assisted Mr. Bell on the chat by answering participants’ questions.
Thirty-eight (38) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of Arizona, California, Connecticut, Illinois, Indiana, Massachusetts, Michigan, Minnesota, Missouri, Nebraska,
New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee,
Texas and Wisconsin. Four participants attended the Web Seminar from locations outside the United States: Canada, China, Panama 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:
- “Discussion of calthrates was interesting and valuable as a 'real world' example.”
- "Useful in explaining some of the dynamics of climate change.”
- “Relevant to topics in environmental geology and oceanography.”
- “It provides a clear illustration of the concept of entropy that can be adopted for the introductory courses of general chemistry at the college level.”
Thanks to the participants and the presenter for the learning opportunity, the interactions, and a job well done!
