|ERESE/NSDL/NSTA Web Seminar, Earth in Reverse - Magnetic Wiggles on the Ocean Floor, 29 January 2008|
|What causes reversals in the Earthís magnetic field? How does the magnetic field help scientists map out the age of the ocean floor as well as the rate of movement in tectonic plates? Why are anomalies in magnetic patterns (known as wiggles) important clues to Earthís ancient geological past?
In this engaging seminar on 29 January 2008 from 6:30-8:00 PM EST, Dr. Chris Symons, Researcher for the Scripps Institution of Oceanography and Dr. Anthony Koppers, Associate Professor of Marine Geology and Geophysics College of Oceanic & Atmospheric Sciences at the Oregon State University, give us an up-close and current view of what itís like to explore these types of questions from the deck of a research cruise ship.
NSDL and NSTA are organizing a web seminar that will spotlight selected resources of animations, real-time data, imagery (and more) to get your classroom rolling. The seminar is designed for educators of grades 5th-12th. Register today by following this http://learningcenter.nsta.org/products/symposia_seminars/NSDL2/webseminar7.aspx link.
