Paper Clip Sailing
Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

Surface Tension (Soap Boat)
Students investigate the affect of soap and water temperature on surface tension.

Surface Tension and 3D Soap Films
Learners are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

Surface Tension
Students examine the concept of surface tension. For this surface tension lesson students complete several experiments to allow them to better understand surface tension.

Surface Tension Grabbers
Learners explore why surface tension is such a very important biological concept. Determination is made on why the myriad of biota that interacts at the air-water interface are vital components of aquatic and marine ecosystems. They...

The Challenge of Ice and Water
Students work in teams to solve a variety of challenges involving water. They move an ice cube from one glass to another without touching the ice or the glass. They move water from one glass to another and they estimate the number of...

Earth & Space Science: Holding it Together
Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Take a Dip: Sticky Water
Pupils complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.

Surface Tension On Coins
Young scholars drop water onto clean coins to determine the tension of each coin and then to graph their findings.

Surface Tension-Driven Flows
Students learn how surface tension changes can cause fluids to flow.
