Surface Tension
A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...
Beyond Benign
Breaking the Tension
The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

Balancing Liquid on a Coin: How Intermolecular Forces Work
Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...
Curated OER
Surface Tension and 3D Soap Films
Young scholars are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.
Curated OER
Surface Tension and Bubbles
Learners investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...
Curated OER
Surface Tension (Soap Boat)
Young scholars investigate the affect of soap and water temperature on surface tension.
Curated OER
Surface Tension
Students view demonstrations that illustrate the surface tension of water. For this properties of water lesson, students observe demonstrations that show how water exhibits surface tension. They explain how the demonstration shows...
Curated OER
Surface Tension
Students study surface tension and determine if soap and heat will affect surface tension. In this tension activity students complete a lab, make a hypothesis and answer questions.
