Surface Tension
Students view demonstrations that illustrate the surface tension of water. In this properties of water lesson, students observe demonstrations that show how water exhibits surface tension. They explain how the demonstration shows surface...
Curated OER
The Chemistry of Life
In this molecule learning exercise, students will use a diagram of a water molecule to see how many electrons and protons the molecule has and use a glycerol molecule diagram to discover carbon atom bonds. 5 fill-in-the-blank questions.
