Friction in Action
There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.

What a Drag
Learners learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a...

Bobsled Challange
Students investigate the effects of materials on the friction between a "bobsled" and the track. They explore the effects of weight on the motion of the bobsled. Students design a bobsled for either fast or slow movement. They discuss...

Science: Avalanche!
Eighth graders examine avalanches after reading excerpts from John Muir's book, "The Yosemite." In small groups, they conduct experiments with flour, sugar, and potato flakes representing different snow consistencies. Then, 8th graders...

Freestanding Structures: A Tech Museum Floor Activity
Students attempt to design the tallest structure that they can with the given materials which are wooden dowels and rubber bands. They discuss the physics of their structure and how they would improve it the next time they built a...

Forces and Balloons
Students investigate the forces of compression, tension and torque on common birthday balloons.
