Science Buddies: Measuring Surface Tension of Water With a Penny

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...

Keep the tension up in the classroom. The class first observes as the teacher creates a dome of water above a glass by adding paperclips into an already full glass. Classmates then work in pairs to see how many drops of water can fit...

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...

In this science instructional activity, students learn about surface tension by performing an investigation with drops of clean and soapy water on a penny.

Ever wonder how water bugs walk on water? A lesson in the STEMonstration provides a brief video presentation describing the concept of surface tension from the molecular level. Pupils then complete a hands-on activity measuring the...

Water is something most of us take for granted. Explore the important aspects of water with a short video lesson. The instructor addresses the key instructional points of the NGSS standard ESS2C. He explains the complexity of the water...

After reviewing the water cycle, zoom in on a raindrop and learn about the physics determining its shape. See actual footage of raindrops falling with high-speed photography! A written description of the same information is also provided...

Learners perform an experiment to measure the density of tap water vs. salt water.

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.
