Sometimes, you don’t want to watch a full-length documentary feature on a subject. Sometimes, you just want to watch a short presentation about one part of a topic to give you a new perspective. That’s where TED comes in. TEDEd is “an invitation to educators to submit their best lessons.” Each lesson is under 10 minutes long, brought to life through animation, and shared online with others interested in teaching similar topics in their classroom. Submit your own lesson, or search from the hundreds available on TEDEd.
