Frontline is great program produced for PBS by WGBH Boston. There are a variety of current events relating to the sciences and humanities. Best of all, they have tons of FULL EPISODES available to EMBED right into your class page! The videos can even be watched chapter by chapter.
Go to the Frontline page and find the video you would like to put into your page.
After you choose the video and start to watch, you can select EMBED on the right hand side. This will give you a quick pop up window. Choose the size you want the video to be on your site, and then copy the code. Use an EMBED gadget to put the video into your class site!
The videos even come with additional links for media resources. For instance this video I use for my Science class has links (on the Frontline page) to an accompanying article in the Washington Post.
