Molymod Vibrating Atoms Model
Product Code : EL-MM-11003
Quick answer: The Molymod Vibrating Atoms Model is a spring-and-ball demonstration of how atoms in a solid vibrate about fixed positions while staying in their lattice. White ball atoms in a 3 x 3 x 3 lattice are joined by 54 springs in a 185 mm cube, and shaking it lightly sets the atoms moving. Lab Exports supplies it as a reseller to schools, colleges and universities.
Specifications
| Item | Specification |
|---|---|
| Atoms | White balls in a 3 x 3 x 3 lattice |
| Springs | 54 connecting springs |
| Dimensions | 185 x 185 x 185 mm |
| Recommended use | Teacher demonstration |
The springs can bend or be displaced with heavy handling, so the model is best kept for demonstration.
How the model is used in teaching
Kinetic theory describes a solid as particles held in fixed positions by forces between them, each particle vibrating about its place. The model shows this directly: the springs play the part of the forces between atoms, and when the lattice is held at arm's length, or rested on a firm board, and shaken lightly, each ball moves on its own yet the lattice keeps its shape.
- Hold the model at arm's length or rest it on a firm board in view of the class.
- Shake it lightly and point out that every atom moves while the lattice pattern stays the same.
- Shake a little more strongly, without straining the springs, to represent heating: the vibrations grow, as they do when the temperature of a solid rises.
- Link what the class sees to expansion on heating and, at far larger vibrations, to melting.
Key features
- Spring-linked lattice that shows atoms vibrating about fixed positions
- 54 connecting springs acting as the forces between atoms
- White ball atoms arranged in a 3 x 3 x 3 lattice
- 185 mm cube, easy to see across a classroom
- Suited to demonstration, as heavy handling can bend or displace the springs

Frequently asked questions
What does the vibrating atoms model demonstrate?
How the atoms of a solid, such as a crystal, are held in a lattice by spring-like forces yet vibrate independently about their positions, the basis of the kinetic theory of solids.
Is the model suitable for students to handle?
It is best used by the teacher as a demonstration, because the springs can bend or be displaced with heavy handling.
