NBC Learn has created excellent free video resources for quite awhile, and you can see their impressive menu at the top of this blog post.
I’ve previously posted about their series on the Civil Rights Movement called Finishing The Dream.
Their new resources are series on the Science of Innovation and Mysteries of the Brain.
But the new one I think will be really be useful is their new ten video collection titled When Nature Strikes: Science of Natural Hazards.
I’m adding that link to The Best Websites For Learning About Natural Disasters, which I’ve just completely updated and revised.
