Cloud Chamber with source

This reusable activity illustrates earth’s rotation and revolution.

• Kit Introduces Concepts of Radioactive Decay
• Students Track the Movement of Alpha and Beta Particles
• Reusable

It also introduces concepts of radioactive decay. With this detector, the tracks of radioactive particles are made visible by the condensation of droplets in a thin layer of alcohol vapor.

It includes a mail-away coupon for the source of alpha and beta particles and requires liquid nitrogen or dry ice.
