I’ve been watching a bunch of TED’s, and while the TEDxTeen talks are good, I am not sure they are right to show in class. However, I wanted to highlight a few of my favorites. I encourage you to go to YouTube and explore more.
BTW you might want to check out the new TEDEducation site on YouTube. There are some cool videos there. Not all of them fit in the TED format, but still worth your time.
