This one is for the science teachers. USA Today has a slide presentation explaining how tornadoes are formed and what to do if you find yourself in the path of a tornado. The slide show is controlled by the viewer who moves a slider at the bottom of the screen to explore the formation of a tornado. Thanks to Open Culture for the link.

If you’re looking for a great video about tornadoes, check out Tornado Intercept from National Geographic. You can watch the entire video for free on Snag Films.

If you have never used Snag Films before, check out my review of the service to see why I like it so much.
