Challenge #TNDO
The principle is simple, it has to be related to your sleep or your dreams!
There’s no judgment here, just an invitation to explore sleep in a playful, creative and free way.
A turnkey activity, designed by scientists and young people, drawing on scientific knowledge from universally proven effective prevention programs and on the knowledge and experience of young people themselves.
To take up the challenge, all you have to do is share a “bedtime story” with each other or on social networks with the #TNDO.
We’ve put a few 💜 into the instructions, but anything’s possible… or almost.

video
Create a video (any accepted format, documentary, animation, interview, etc.) of 30 seconds to 1 minute 30 seconds maximum filmed vertically.
Everyone has bedtime stories; the proof is in the videos of the creators of this project!
Favorite 💜 discover the videos of American students on the importance of sleep.

podcast
Records an audio file of 30 seconds to 3 minutes maximum.
Favorite 💜 podcasts: the offbeat podcasts for kids from “La puce à l’oreille”
photo
Share one or two of your photos (no more) and explain in a sentence or two its connection to sleep if needed.
Favorite 💜 photo: “My room project” by John Thackwray takes us on a journey around the world through photos of bedrooms. Great for learning about different sleeping environments.

COMIC STRIP

Tell us a story of your own, in the format of a comic strip of 6 to 8 panels maximum. You can do it on a page or in WEBTOON scrolling format.
