Changes of State: Evaporation, Condensation, Freezing, and
Melting - Introducing a Free Online Resource for Middle School Chemistry
|
This Web Seminar took place on July 26, 2012 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 second 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 second presentation in a series of six web seminars covering each of
the six chapters in middleschoolchemistry.com. During the program, Mr. Kessler introduced
participants to the website and explained the format of the activity-based lessons.
He then delved into the big idea for Chapter 2: Changes of State: Evaporation, Condensation,
Freezing, and Melting. Participants learned strategies for implementing the lessons
by watching several videos and animations featuring demonstrations of each concept.
Mr. Kessler also discussed the connection between the lessons and the National Framework
for Science Education.
One hundred and twenty-seven (127) participants were present at the live Web Seminar
in addition to the presenter and NSTA staff. Participating educators represented
the states of Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Florida,
Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland,
Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey,
New Mexico, New York, North Carolina, Oregon, Oregon, Pennsylvania, South Carolina,
Tennessee, Texas, Virginia, Washington, West Virginia, and Wisconsin. In addition,
four participants joined the program from locations outside the United States:
Canada, Germany, Puerto Rico, 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:
- “Having such organized, high quality resources in one web site is wonderful.
The flow of concepts is also very helpful.”
- “The content provided gave good examples and resources for use in the classroom.
VERY VALUABLE!”
- “The animation clips will be extremely helpful to show molecule movement when
discussing states of matter.”
- “Intact 5E lessons and variety of multimedia content make this very easy to
implement!! Love it!”
Thanks to the participants and the presenter for the learning opportunity, the interactions,
and a job well done!
