Subject: [NOVA Teachers] November 18, 2003
Hello Educators,
In next week's "Magnetic Storm," NOVA explores what creates Earth's
magnetic field and why it might be headed for a reversal, a
phenomenon in which the planet's magnetic poles reverse polarity.
(Subjects covered: earth science, geology, physics, gravity
and forces)
In the coming weeks:
Nov. 25 -- Volcano Above the Clouds
http://www.pbs.org/nova/kilimanjaro/
Dec. 2 -- varies (check your local listings)
Dec. 9 -- Orchid Hunter (R)
http://www.pbs.org/nova/orchid/
