Surface Tension and 3D Soap Films

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...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Students explore physical science by participating in a water properties experiment. In this surface tension lesson plan, students utilize pennies, water, a dropper and soapy water to test the different surface tensions with numerous...

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...

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...

Students investigate surface tension, adhesion and cohesion. In this surface tension lesson plan, students complete 3 activities to better understand the concepts of surface tension, adhesion and cohesion. Students add drops of water to...

Students investigate cohesion, adhesion and surface tension through observations and lab experiments. In this cohesion, adhesion and surface tension lesson plan, students rotate to 5 stations around the room and experiment at each...

Have you ever wondered what makes water 'bead' up on a freshly waxed car? In this project you'll investigate the chemistry of surface tension by measuring how many drops of water a penny can hold.
