This reusable activity illustrates earth’s rotation and revolution.
- Kit Introduces Concepts of Radioactive Decay
- Students Track the Movement of Alpha and Beta Particles
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.
