Observing Ionizing Radiation Using A Cloud Chamber Kit

Expand your nuclear chemistry demos beyond simulations with this cloud chamber activity. Students observe the contrails formed as ionizing radiation travels through a cooled, supersaturated vapor. They illustrate and explain what is happening in the cloud chamber on a particulate level while learning about nuclear processes and nuclear equations. Students then connect their observations of ionizing radiation to occurrences and uses of radioactive isotopes in the world. Materials for 5 demos.
