Abstract

A four-part activity utilizing a graphing calculator to investigate nuclear stability is described. Knowledge acquired through the activity provides background for answering the societal question of using nuclear materials for energy production. Analysis is used to determine a mathematical stability function for stable light isotopes (Z < 20). Further analysis of stable naturally occurring isotopes suggests that stability occurs as a two-part piecewise function. A decay series illustrates a process of decay. The paired daughter products of uranium-235 fission provide insights into the problems associated with nuclear waste.
