Rolling Marble Runs

-Elizabeth, Science Teacher in NYC
Unit Description
A toy inventor's marble run keeps getting stuck — the marble never makes it to the end. Students investigate what makes a marble roll in the first place, then explore how ramp angle, surface friction, and energy transfer during collisions all affect how far and fast a ball travels. They build a baseline marble run first, then tinker their way toward a final design challenge: a 3D cardboard box run that keeps a ball rolling for five seconds or more.

What Students Learn
How gravity and unbalanced forces cause objects to move
How steepness affects the speed and energy of a rolling object
How friction removes kinetic energy and slows objects down
How energy transfers between objects during collisions
