Take the TED-Ed July Challenge!

Want to keep your brain fit this summer — and learn 31 new ideas in the month of July? Do both by signing up below to take the second annual TED-Ed July Challenge! Here’s how it works: Beginning on July 1, once a day for 31 days, you’ll receive a TED-Ed Lesson in your inbox — chosen just for this challenge. Then, watch the video and answer the questions. That’s it! You can do the lesson on the same day you get it, or you can wait and do a few at the same time — just so long as all 31 lessons are done in July. However you choose to do it, we’re cheering you on!
