Science Friday

If you can't manage to catch Ira Flatow every Friday on the radio you can get it as a podcast. They break up the 2 hour program into individual stories and remove all the station identifications and local news. Good stuff for your own knowledge even if you don't share it with your students.

You may also be interested in the Science Friday Videos. These are videos by or about guests or videos related to the stories covered. The more I look the more good stuff I find here.
