SAMPEX - Yohkoh: Solar Modification of Relativistic Electrons in the Earths Radiation Belts
The Solar Anomalous and Magnetospheric Particle Explorer, SAMPEX, measures fluxes of energetic particles from the sun, the Earths magnetosphere, and cosmic ray sources over a broad range of energies. The four instruments aboard SAMPEX are the Low-Energy Ion Analyzer (LEICA), The Heavy Ion Large Telescope (HILT), The Mass Spectrometer Telescope (MAST), and the Proton-Electron Telescope (PET). The Soft X-ray Telescope on the Yohkoh satellite takes daily full-disk soft X-ray images of the Sun. Comp

Wildlife in India
Check out this terrific short video from explore.org on the wildlife in
India. The animals face the threat of extinction, and the anti-poaching
laws are not being truly enforced. Some, however, are doing great work
in attempting to reverse the destruction and protect India’s wildlife.
“People for Animals” is one such great organization, and the explore
team of explore.org filmed this inspirational short film.

Influenza Pandemic of 1918
One of the worst natural disasters in recorded history was caused by a virus. The influenza pandemic of 1918 killed at least 20 million people killing more people than WW I. This is best used to show how the smallest germs are more powerful than man-made weapons. Original footage. Needs a word wall and map to make the lessons more important to students. Great for an exercise of comparing large such death numbers such as The Black Death.

The Dust Bowl Years
I was inspired to make this video after watching the History Channel's special presentation of "Black Blizzard" which described in depth how and why the Dust Storms of the 1930's happened. I knew the storms were bad, but in my wildest imagination I could never fathom the magnitude of destruction the phenomenon caused. How the people of the time made it through without going mad is truly astonishing. It is to the survivors and their families that I humbly dedicate this video.
