National Geographic offers a good series of more than one hundred YouTube videos designed to provide viewers with concise explanations of the big concepts of a variety of topics in science. The series includes videos about volcanoes, plastics creation and recycling, the solar system, and invasive species.

The latest video added to the National Geographic 101 series is Deserts 101. Deserts 101 covers exactly what you would expect to find in it. The video explains the conditions that create deserts, types of deserts, and why desertification is starting to occur in new places.

This video is the right length and has the right style and pacing to make it an excellent choice for a flipped lesson intended to introduce the big concepts of a lesson about deserts. My go-to tool for making flipped lessons continues to be EDpuzzle. You can learn how to use EDpuzzle by watching the following video.
