Crash Course Biology is an educational YouTube series from 2012 hosted by Hank Green. The goal of the series was to present the information covered in an AP Biology course in 40 10-minute episodes, covering topics from taxonomy to biological molecules to the evolution of plants and animals. The videos have been viewed 8.5 million times on YouTube, and the series was picked up by Khan Academy. I wrote the scripts for 37 of the 40 episodes, beginning with episode #4, Eukaryopolis - The city of animal cells.
Crash Course Ecology is a similar YouTube Series covering the basic tenets of Ecology in 12 videos. I wrote the scripts for all episodes, which have been viewed 1.5 million times and also rereleased by Khan Academy.
