About
Crash Course is a free YouTube educational video series created by John and Hank Green and produced by Complexly. Each series consists of 10-50 episodes covering a single subject at a high-school to introductory-college level, with hosts varying by topic expertise. Subject areas include World History, U.S. History, Biology, Chemistry, Literature, Economics, Philosophy, Computer Science, and Film History. Many homeschool families pair Crash Course videos with a spine curriculum for enrichment, though content is secular and occasionally presents perspectives that faith-based families may want to discuss.
