Curated OER
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...
