History of Science is a Crash Course series that just came to my attention when I stumbled onto The Atomic Bomb: Crash Course History of Science #33. The entire series features videos hosted by Hank Green in which he explains how big questions in science were answered and how big breakthroughs were made. Like most Crash Course videos these are heavy on the presenter (Hank in this case) and light on visual aids. And they're probably best used with students who already have a firm understanding of the basics of the topics.
Try using these videos in EDpuzzle to build comprehension and reflection questions for your students to answer while watching or after watching the videos.
