Science Buddies: Build a Motorboat Powered by Surface 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...

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...

Surface tension helps us perform some simple—but impressive science. The video presents many experiments to briefly explain surface tension. From the surface tension on milk and coffee to water, the experiments demonstrate the strength...

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...

Here is a six-minute video of a pair of electrical engineers that illustrate how to build a wind turbine. A list of materials is provided, along with general guidelines for your class. Use this to introduce turbine design to your...

Science Bob presents instructions for a science demonstration of how to build a soap-powered model boat using common supplies with information on how it works.

Step-by-step instructions, with photos, of how to construct and test a wind turbine that produces energy. This experiment does require preparation as it uses PVC pipes, a small motor, and a multimeter, for example.

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...

Build your own bathtub or pool toy from simple craft materials in this fun activity. You will build a rubber-band-powered boat that can zip across the surface of the water after you wind up the rubber band.

A helpful activity describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can hold...
