About This Lesson
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.) ; Sample Learning Goals:
•Describe how a neutron can give energy to a nucleus and cause it to fission.
•Explain the byproducts of a fission event.
•Explain how a chain reaction works, and describe the requirements for a sustained chain reaction large enough to make a bomb.
Another excellent resource from Phet. Allows you or your pupils to control variables.
