Task · part of 6. Nuclear Energy. Do ONE, then discuss nuclear electricity
6(a). Fission, a mousetrap reactor, and critical mass
Optional May not apply
Draw how nuclear fission happens. Observe a mousetrap reactor set up by an adult and use it to explain how a chain reaction could be started. Explain how one could be stopped or controlled in a reactor, and what "critical mass" means.
Notes and warnings
Note. The mousetrap reactor is "setup by an adult"; you observe it and use it to explain a chain reaction.
