Educated Earth for Edcuation

Educated Earth is a very nice site that brings you a wide variety of videos, photographs and articles about the science of our earth. I found a wide variety of videos from an octopus that attacked a shark, to a science demonstration of blowing up bathtubs with a chemical reaction of alkali metals and water.
The only real problem I see is that many of the videos are not hosted on the site, so if your district like mine blocks Youtube and Google Video you may not be able to view them.
