BBC Explainers are short explanatory videos produced for the BBC. Through Lee LeFever's recent post I learned about the process used to create the BBC Explainers videos. Central to Lee's post is this video explanation of the creation process. The video might be over the heads of middle school and some high school students. The video is worth watching for the information that you can pass to your students.
