    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

AGU-NESTA GIFT Workshops

NESTA and AGU have teamed up to organize the AGU-NESTA GIFT workshop at American Geophysical Union Fall Meetings in San Francisco, California.  These workshops are designed for K-12 classroom teachers, and bring together some of the world's best geoscientists with education specialists to share their state-of-the-art Earth and space science knowledge with exemplary classroom resources to help bring Earth and space sciences alive for your students.

Access materials shared at the 2011 AGU-NESTA GIFT workshop here.

The American Geophysical Union is the world's largest professional society for geophysicists internationally, with over 50,000 members worldwide.  Teachers can join AGU for only $20/year, and receive a weekly science newsletter - EOS Transactions - with updates on the geosciences from this worldwide community of scientists.  Teachers can attend the AGU-NESTA GIFT workshop at no charge, but they must register in advance.  Workshops are held each year at the Fall AGU Meeting, held typically in the second week of December.  Information about the upcoming GIFT workshop is posted several months in advance, and can be found on the AGU Teacher page.
