Available YouTube Channels:

LightSpeed (content filter) has automatically "allowed" (meaning ‘made available for students’) some channels that are designated as strictly educational. A few examples of automatically "allowed" channels are: TedED, National Geographic, Crash Course, Minute Physics, Khan Academy, Animal Planet, NASA Scishow, History Channel, and Discovery Networks.

Note: At this time, LightSpeed does not provide a comprehensive list of all of their automatically "allowed" channels; however we do know that at least these channels COULD BE on the "Allowed List" (and likely many others are open as well)
