This app provides access to more than 300 full-length programs shown on PBS. I'm most impressed with the episodes for the program 'Nature', but can see many more applicable uses in a classroom setting.

The app allows you to save your favorite programs or episodes for even easier access. You can also watch previews for upcoming programs.

I recommend simply obtaining this app and browsing the programs to find ones that meet your needs.

Please note that this app is rated 9+; it's possible to encounter programs that may be inappropriate for students under the age of 9. No matter the age level you teach, be sure to preview any program you wish to show to students.
