Studying the Magnetosphere in the Classroom Sten Odenwald and Bill Taylor (Both at NASA/Goddard Space Flight Center, Greenbelt, MD) The New Millennium Magnetosphere: Integrating Imaging, Discrete Observations, and Global Simulations, Sixth Huntsville Modeling Workshop, Guntersville, Alabama, 26-30 October 1998. The magnetosphere is, at once, one of the most familiar and the least understood elements to the Earth's environment for grades 7-12 in the typical earth and physical science curriculum. Students learn that it resembles a bar magnet, but what they seldom encounter is the concept of the geomagnetic storm and its connections to solar activity and human technological impacts. We will demonstrate a series of classroom activities that have been designed by teachers for the NASA IMAGE satellite program. These activities bring geomagnetic storms and 'geospace' into the classroom for direct investigation. They provide a valuable 'third dimension' to typical classroom discussions, and follow the new educational practices recommended by local and national education guidelines.
