This is a spreadsheet that simulates radioactive decay. You start with a grid of 1s that decay to 0s. The decay for each is random. It runs through 8 'generations' of decays. Each 'generation' can be assigned any unit of time you wish. A record of everything that happens is recorded into a results table that can be used by the class to plot results. A log graph and a linear graph are both produced, each of which can be printed for a class to use (changes the axes as you see fit). The decay modifier changes the half-life and is an arbitrary value, so play around with it.
