If H2O is water and H2O2 is hydrogen peroxide, what is H2O4? Drinking, bathing, and cooking among others. Viewers of a short video explore water through its molecular structure, its ability to stick to itself through adhesion (cohesion is discussed as well), and the differences between hydrophobic and hydrophilic substances. They also learn about Henry Cavendish's contributions to science.

Instructional Ideas
- Support concepts introduced in the video — adhesion, cohesion, hydrogen bonds, density, hydrophobic, and hydrophilic substances — with activities, labs, and discussion after showing the video
- Have learners create Venn diagrams with the following words: adhesion and cohesion; and hydrophilic and hydrophobic, then share with the class
Classroom Considerations
- Teachers should have access to a computer, the Internet, and a projection system
- Video two in a series of 40
- This video is hosted on YouTube
Pros
- Simple and effective visuals make the video an engaing and easy-to-understand resource
- Great overview of water as a compound
Cons
- Uses quick, dry humor that some pupils may not understand
