According to TED-Ed:
TED-Ed's mission is to capture and amplify the voices of great educators around the world. We do this by pairing extraordinary educators with talented animators to produce a new library of curiosity-igniting videos. A new site, which will launch in early April 2012, will feature these new TED-Ed Originals as well as some powerful new learning tools.
For those who can't wait that long, we're pleased to announce the official launch of TED-Ed's YouTube channel featuring all of our new videos. Also, we are happy to extend an open invitation for the nomination of educators and animators and the suggestion of lesson ideas.
