Serc: Mn Step: Surface Tension With Soap Film
An investigation into the effect soap has on the surface tension of water. Pupils create three-dimensional shapes using toothpicks and clay, dip them into soapy water, and make observations and formulate questions about the soap film.
Biology Corner
The Biology Corner How Is the Surface Tension of Water Affected by Soap?
Here is a classic lesson regarding surface tension. This worksheet combines properties of water and the scientific method together for a hands on investigation.

Teach Engineering: Capillarity Measuring Surface Tension
Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and adhesive forces (the forces that causes water to "stick" to solid...
Frostburg State University
Frostberg University: Surface Tension and Droplet Size
Discusses the role of surface tension in determining the size of water droplets. Explanation of why a small amount of liquid in a dropper will never run out.
