Plate Tectonics Made to Order
Learn about Plate Tectonics!
The Plate Tectonics Made to Order Web Seminar,
produced in collaboration with the National Science Digital Library (NSDL) and the
Scripps Institution of Oceanography, was held on Thursday, November 30, 2006, from
6:30 p.m. to 8:00 p.m. Eastern time. Scripps Researchers Dr. Anthony Koppers and
Dr. Christina Symons who are associated with the Enduring Resources on Earth Science
Education (ERESE) website were on hand to present.
The seminar examined plate tectonic theory, seamounts, and hot spots utilizing "just
in time" resources for teachers to use in teaching these concepts from ERESE, the
NSDL Middle School Portal and DLESE Teaching Boxes.
Eighty-eight (88) participants were present in addition to the presenters, the NSDL
moderator, and the NSTA staff. Participating educators represented the states of
Arizona, California, Colorado, Connecticut, Florida, Georgia, Illinois, Iowa, Maine,
Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina,
Ohio, Oregon, Pennsylvania, Puerto Rico, Rhode Island, South Carolina, Tennessee,
Texas, Virginia, Washington, and Wisconsin.
The presenters talked about plate tectonic boundaries and the basics of plate tectonic
theory through the use of maps and illustrations. In studying the ocean floor, the
Mid-Atlantic ridge is an example of a divergent boundary that forms new crust. The
participants learned that the magnetic polarity in these areas reverses during the
formation of these sections of oceanic crust and gives researchers insights on the
age and length of these formations. Hot spots, like those found forming the Hawaiian
Island chain, are usually formed away from plate boundaries and arise from mantle
plumes. Using the ERESE website and other NSDL sites can better demonstrate these
concepts in your classroom. All participants received a copy of the NSTA SciGuide
on Earth Structures, grades 9-12.
Here are some comments provided by the participants at the end of the Web Seminar:
- "The chat for this seminar was very vibrant and interesting. I learned some
neat tectonic math that I can use with my students."
- "I enjoyed the graphics and being able to interact with other teachers in the
same subject area."
- "This was the first web seminar I attempted. I'm kind of a technophobe, but
this was pretty painless... I think I'll really enjoy some of your other offerings."
- "I like the interactive [nature of the program] and the ability to be around
other active learners! I hadn't been aware of how the plates have changed directions
- that was cool!"
Thanks to the participants and the presenters for the learning opportunity, the
interactions, and a job well done!
