Crash Course and is the brain-child of vlogbrothers Hank and John Green. It is a YouTube channel that addresses a wide variety of topics. In the beginning, John covered the historical and literature side, brother Hank covered the science side. Each “Crash Course” video is 10-15 minutes long and quick a succinct recap of concepts you would cover in one of your classes. Each video is very well done and tries to meet students at their level.
After forming a partnership with PBS Digital Studios, Crash Course has been able to expand their offerings. Crash Course now offers a variety of science courses (astronomy, chemistry, biology, ecology, anatomy, and physics) as well as new hosts that are experts in their given fields. The content is geared toward a more AP/early college level, however I have been able to use these videos with all levels of high school with success. An answer key for each video is included. Files are in .doc and .pdf formats.
This bundle currently includes question sheets (with answer keys) for the following Crash Course videos:
Anatomy and Physiology (47 videos)
Astronomy (46 videos)
Big History (10 videos)
Biology (40 videos)
Chemistry (46 videos)
Ecology (12 videos)
Physics (46 videos)
