This week Hank and John Green added the thirtieth episode to their chemistry Crash Course series. The latest episode is all about pH. Students will learn what pH is and how to calculate it. Like all Crash Course videos your students will probably have to watch the video twice or rewind the section on calculation to catch it all. The video is embedded below.

Applications for Education
The next time your students are in need of some chemistry review materials to watch online, they might want to visit the Crash Course Chemistry series from Hank and John Green.
