    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.

The Sun-Earth Connection and Geomagnetism: How the Sun, space weather, and Earth's magnetic field influence our planet's environment

A Windows to the Universe Workshop presented on July 24, 2006, at the
6th Annual Environmental Health Sciences Summer Institute for K-12 Educators
The University of Texas M. D. Anderson Cancer Center Science Park - Research Division at Smithville

Earth beside a SunspotThis workshop covered three major topic areas:

  • magnetism, space weather, and Sun-Earth connections
  • ultraviolet (UV) "light" - its emission by the Sun, interactions with Earth's atmosphere, and effects on people and Earth's environment
  • radiation - types, sources, units of measurement, effects

The workshop included several hands-on activities.

List of Hands-on Activities

Write-ups of the hands-on activities conducted at the workshop can be found at the links below:
