National Geographic’s YouTube channel includes a fun playlist of short videos about interesting science facts. The playlist, called Today I Learned or TIL for short, is comprised of 60 to 90 second videos on things like “why is the ocean salty?” and “how chameleons change color.” The playlist is embedded below.

Applications for Education

The videos in Today I Learned aren’t long enough to be full flipped lessons, but they could be useful as warm-up material to spark your students’ curiosities about a topic.
