Atoms

Chain Reaction
Simulation of a chain reaction using many mouse traps contained underneath a protective plastic dome.

Geiger Counter and Radioactive Materials (*)
We have an old Geiger counter available to show students how radioactivity is measured and quantified.

Nuclear Decay
Ping pong balls with Velcro to show splitting of parent nuclei into daughter nuclei or other radioactive decay.

Piezoelectric Effect
Convert mechanical energy into electrical energy by compressing a crystal to produce a visible flash of electricity.

Solid State

Crystal Structure
Physical models of many crystalline structures to demonstrate solid state geometries.

Photocell
A photovoltaic cell, LEDs, and strong light source are combined to show an example of solid state physics being used to produce electricity.
