Serc: Mn Step: Surface Tension With Soap Film
An investigation into the effect soap has on the surface tension of water. Students create three-dimensional shapes using toothpicks and clay, dip them into soapy water, and make observations and formulate questions about the soap film.

Teach Engineering: Surface Tension Lab
Students extend their understanding of surface tension by exploring the real-world engineering problem of deciding what makes a "good" soap bubble. Student teams first measure this property, and then use this measurement to determine the...

Teach Engineering: Simple Coulter Counter
Students build and use a very basic Coulter electric sensing zone particle counter to count an unknown number of particles in a sample of "paint" to determine if enough particles per ml of paint exist to meet a quality standard. In a lab...

Teach Engineering: Pulley'ing Your Own Weight
Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and...

Teach Engineering: Measuring Lava Flow
Students learn how volume, viscosity and slope are factors that affect the surface area that lava covers. Using clear transparency grids and liquid soap, students conduct experiments, make measurements and collect data. They also...

Teach Engineering: Pyramid Building: How to Use a Wedge
Young scholars learn how simple machines, including wedges, were used in building both ancient pyramids and present-day skyscrapers. In a hands-on activity, students test a variety of wedges on different materials (wax, soap, clay,...
