## Description

In this Science NetLinks lesson, the second lesson in a three-part series about isotopes, radioactive decay, and the nucleus, students are asked to simulate radioactive decay by pouring small candies and counting which candies fall with their manufacturer's mark down or up. The exercise they go through of predicting and successively counting the number of remaining "mark-side up" candies should help them understand that rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.
