This method of measuring a rate won't work for radioactive decay.We know that radioactive substances disintegrate at a known rate, however. It is the length of time required for the disintegration of one-half of a given number of nuclei of a radioactive element. Suppose we have 100 nuclei of a radioactive isotope.This is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus.The first lesson, Isotopes of Pennies, introduces the idea of isotopes.They need only know that such calculations are possible. 79.) In this lesson, students will be asked to simulate radioactive decay by pouring small candies, such as plain M&M's® or Skittles®, from a cup and counting which candies fall with their manufacturer's mark down or up.

The exercise they will 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.This lesson can be done in two, 45-minute class periods.It may be combined with the Frosty the Snowman Meets His Demise: An Analogy to Carbon Dating, which can be done while students are flipping their candies.
