I6-40: MOLECULAR MOTION DEMO - SOLIDS

ID Code: I6-40
Purpose: Model the behavior of solids.
Description: A set of small balls of equal mass is placed in the vibrator in a curved glass dish with the concave side up. The gravitational force caused by the curvature of the dish causes them to form an array, corresponding to a crystal lattice. As the vibrator motion is increased, the molecules do not move about randomly, but rather vibrate about their original positions, representing vibratory motion of atoms in a crystal lattice.
