The TED-Ed project — TED's education initiative — makes short video lessons worth sharing, aimed at educators and students. Within TED-Ed’s growing library of lessons, you will find carefully curated educational videos, many of which are collaborations between educators and animators nominated through the TED-Ed platform.
