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.

Roller Coaster Project
Emerging engineers work in teams to design pipe insulation roller coasters for marbles that meet specific parameters. They are required to label along the track the areas where kinetic and potential energy are highest and lowest, where...

Ramp and Review (for High School)
Rolling for momentum. As part of a study of mechanical energy, momentum, and friction, class members experiment rolling a ball down an incline and having it collide with a cup. Groups take multiple measurements and perform...

Investigation: Conservation of Energy
By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...
