This video (12:33) is the first in the Crash Course Biology series.  "And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert Lewis?"Re-watch the whole video = 00:00Carbon is a Tramp = 01:51Electron Shells = 04:23The Octet Rule = 06:52Gilbert Lewis = 05:09Covalent Bonds = 04:41Polar & Non-Polar Covalent Bonds = 07:58Ionic Bonds = 08:29Hydrogen Bonds = 10:11

Reviewer Comments:

Hank Green (along with his brother John Green) has created these engaging and accurate “crash course” videos on topics ranging from chemistry to world history, biology, literature, and ecology.  This particular video focuses on water and discusses cohesion, surface tension, and adhesion as well as hydrophilic and hydrophobic substances.  Finally, Green stresses water’s unusual density and heat capacity properties.  This video can serve multiple purposes from use in the classroom to facilitating one’s own lifelong learning.
