MinuteEarth is a popular YouTube channel whose videos I’ve featured a handful of times on this blog. Their short videos provide explanations of interesting science topics like why rivers curve, how some waves get so big, and why it is hot underground. A few years back MinuteEarth published a video about the process their team uses to produce their videos.
This video could be helpful in showing students the process of creating a good, concise explanatory video. In particular, it is notable that the visual components are the last things added to the video.
