Molecular Motion Simulation by Mechanical Overhead Projector Shaker of little Pink Spheres

Demo Description

Simulate molecular motion by shaking plastic marbles (which represent molecules).

Scientific Principles

Molecular Motion

Equipment

  • Simple mechanical agitator

  • Small plastic marbles

Equipment Location

  • The apparatus is in Kit (094) on [D-1-2].

Instructions

The simple mechanical agitator has periodically shaking walls.

Small spheres placed on the space between the shaking walls go into two dimensional motion colliding with themselves and with the moving walls.
