  • Logan Smalley: Right now, somewhere out there,

  • there's an educator delivering a mind-altering lesson to their class.

  • Adam Savage: I want to engage your brains in this.

  • Chris Anderson: Trying to get my head around how vast our Earth is.

  • LS: But that lesson only reaches the students in that room.

  • What would happen if we could capture that lesson?

  • AS: This is a toothed wheel.

  • LS: What if, oh, animators and visualization artists could bring that lesson to life?

  • CA: There's an object we see every day that would literally fit one million Earths.

  • AS: It's got a bunch of notches, and it's got a bunch of teeth.

  • This was Fizeau's solution.

  • LS: When that lesson lands, curiosity is ignited.

  • CA: It seems impossibly big.

  • AS: Something interesting happens.

  • CA: But in the great scheme of things, it's just a pinprick.

  • AS: A door is starting to close on the light beam that's coming back to his eye.

  • LS: Then that group of students is one thought closer to being

  • what every teacher hopes their students will become:

  • a lifelong learner.

  • AS: Based on the difference between the two stations.

  • CA: The quest for knowledge and understanding never gets dull. It doesn't.

  • AS: He calculates the speed of light to within two percent of its actual value.

  • CA: The more you know, the more amazing the world seems.

  • LS: That's the central mission of TED-Ed --

  • to capture and to amplify the voice of the world's greatest teachers.

  • AS: He does this in 1849.

  • CA: It's the crazy possibilities, the unanswered questions, that pull us forward.

  • So stay curious.

  • (Music)

  • Stephanie Lo: TED-Ed is really an invitation to teachers all around the world

  • to submit their best lessons.

  • Jordan Reeves: We review each submission, and we work with the educators

  • to refine the lesson and make sure that they're less than 10 minutes long.

  • Bedirhan Cinar: From there, we mail out these portable recording booths.

  • A teacher pulls up their final lesson, presses record,

  • and then can instantly share it with our animation team.

  • SL: It's also an invitation to animators.

  • We are looking for talented animators to get involved,

  • submit their reels, and help us animate these incredible lessons.

  • LS: Right now, there's a gifted educator somewhere out there delivering a life-changing lesson.

  • The TED-Ed Team hopes that anyone who's passionate about education

  • will help us find that teacher, capture that moment,

  • and amplify it the way that it deserves to be amplified.
