Teach Engineering: Tension Racers!
Students see how different levels of surface tension affect water's ability to move. Teams "race" water droplets down tracks made of different materials, making measurements, collecting data, making calculations, graphing results and...

Teach Engineering: Get Your Charge Away From Me!
This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the...
TeachEngineering
Teach Engineering: Down With the Clip!
Students see how surface tension can enable light objects (paper clips, peppercorns) to float on an island of oil in water, and subsequently sink when the surface tension of the oil/water interface is reduced by the addition of a...

Teach Engineering: Let's Get Dirty
In a very hands-on activity, students observe and feel the differences between two cleaning methods, with and without hand soap, using coffee grounds to represent "dirt."Most of the dirt and bacteria on our hands is encased in a thin...
TeachEngineering
Teach Engineering: Penny Perfect Properties (Solid Liquid Interactions)
Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test...

Teach Engineering: Surface Tension
Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a...
TeachEngineering
Teach Engineering: Surface Tension Basics
Students are presented with the question: "Why does a liquid jet break up into droplets?" and introduced to its importance in inkjet printers. A discussion of cohesive forces and surface tension is included, as well as surface acting...
TeachEngineering
Teach Engineering: Capillarity Measuring Surface Tension
Learners 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...

Students observe and investigate why water has a strong surface tension.
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.
Exploratorium
Exploratorium: Soap Bubbles
A scientific look at soap bubbles. Find out what it is about soap and water that allows bubbles to occur, how bubbles stick to each other, and why they are always a sphere. There are even formulae for making your own bubble solution.
Wolfram Research
Wolfram Science World: Surface Tension
The concept of surface tension is explained and the formula used to calculate it is presented. Includes an example of using the equation, and a table of surfaces tensions is given.
