Crash Course is an educational YouTube channel created by John and Hank Green that offers fast-paced, content-rich video series on world history, U.S. history, biology, literature, economics, and more. Aimed at roughly middle school through college, episodes combine narration, animations, and humor to cover big ideas and key details in under 15 minutes. Parents and teens appreciate its ability to make dense subjects more approachable and to serve as either a preview or review of course content. It’s best paired with slower reading and discussion, but as a free resource, Crash Course is invaluable for visual and auditory learners.

Ideal for motivated middle and high schoolers who enjoy video learning, want concise overviews or review of key topics, and can pause, rewind, and take notes; a good match for families comfortable combining free videos with separate readings, problem sets, or labs.

Pros

Offers more than 45 free, fast-paced courses in subjects ranging from biology and chemistry to world history, economics, study skills, and more; highly engaging hosts and strong scripting make complex topics accessible for many middle school, high school, and even early college students; widely used by secular homeschoolers as a video spine or enrichment. 

Cons

Videos move quickly and assume decent background knowledge, which can overwhelm some learners; humor and references occasionally feel edgy or snarky, so many parents pre-screen for younger or sensitive students; there is limited built-in practice, so it doesn’t function well as a stand-alone curriculum. 

As a free, open-access resource, Crash Course does not require or accept ESA or charter payments; however, charter-school teachers frequently assign it as part of funded social studies or science courses.

Crash Course Mission

The mission of Crash Course is to provide free, high‑quality courses in everything from world history and biology to economics and literature so that anyone, anywhere can get a rigorous introduction to big ideas. Through tightly scripted, fast‑paced videos packed with graphics, jokes, and real‑world context, the team aims to make complex subjects feel approachable without sacrificing depth. By keeping all of their content on YouTube at no cost, Crash Course helps level the academic playing field for students who might not otherwise have access to great teachers or advanced classes.

Crash Course Story

Crash Course launched in 2012 when brothers John and Hank Green partnered with YouTube to create full video courses in World History and Biology. Their experiment—mixing dense subject matter with humor, pop‑culture references, and high‑end animation—struck a nerve with teens and teachers around the globe. Over the years the project has expanded into a full educational studio producing dozens of series across humanities, social sciences, and STEM, collaborating with diverse expert hosts. What started as two brothers filming in a basement has grown into a staple of online learning used in classrooms and homeschools on every continent.

FAQ: Additional Details about Crash Course

A typical Crash Course “class” might involve a teen sitting with a notebook in front of a laptop or TV, watching a 10–15 minute episode full of quick-cut visuals, jokes, and thoughtfully dense explanations. You’ll hear pens scratching as they pause to jot down key ideas or rewind a confusing section, and after the video many families segue into a discussion, primary-source reading, or related writing assignment while the ideas are still fresh.

Crash Course is a large library of free, fast-paced YouTube courses for teens and adults covering history, science, literature, social sciences, and more. Families typically choose a subject-aligned playlist (such as World History, US History, Biology, or Government), then integrate episodes into their weekly schedule as lecture-style content paired with readings, note-taking, and projects.

Younger teens benefit from parents co-watching at first, modeling active note-taking and facilitating discussion. Older students often watch independently, then meet with a parent once or twice a week to review notes, ask questions, and plan written or project-based assessments tied to the episodes.

Learners should have solid middle- or high-school–level reading comprehension to get the most out of the series and enough maturity to handle frank discussions of history, politics, and science. Parents of younger or sensitive teens may want to pre-screen specific series for tone and topics.

Crash Course’s fast‑paced, high‑energy videos are a big hit with many ADHD, gifted, and teen learners who like humor and condensed content. However, the speed and density can overwhelm some autistic or anxious kids, so families may want to slow playback, watch in short bursts, and follow up with discussion or notes.

Not designed specifically for 2e, but many 2e teens love the fast‑paced, humorous explanations. Because the info density is high, pausing, rewatching, and doodling notes can help learners with processing‑speed or attention differences.

There is no purchasing or subscription required for the core videos, so there is no formal refund policy; families can simply stop using the material if it isn’t a good fit.

Not a good fit for very young learners, students who need slow, highly scaffolded explanations, or families wanting a faith-based or strictly textbook-driven program; also less suitable for kids who require lots of hands-on activities and real-time interaction.

Families wanting more structured, practice-heavy video instruction often consider Khan Academy, Thinkwell, or Derek Owens; for history specifically, programs like History Quest, Story of the World (not fully secular), or Big History Project can pair well with or replace Crash Course.

Crash Course continually launches new series and refreshes older ones, and many courses now have companion materials like reading lists, practice questions, and teacher resources. Families can build multi-year humanities and science tracks by combining different playlists as they are released.

Use Crash Course as a “lecture component”: assign a specific playlist, have students take Cornell-style notes, then immediately follow up with problems, primary sources, or written narrations from a different resource to cement learning.
