Discovery Education includes a growing population of videos and channels which are available in multiple languages.
When the channel is available in another language, the globe icon will appear in the buttons at the top of the channel. The available languages will appear and can be selected to toggle the resources in the channel. While every resource in the channel may not be available in that language, it will show the resources that are.
While Discovery Education has a large variety of resources in various languages, there is also a collection of resources that have an identical pair resource - in both English and Spanish or other languages. When a video is available in other languages, a button will appear at the top of the video player page where you can select the language version you'd like to explore.
