Modeling Radioactive Decay Using Dice: An Inquiry Activity
In this activity, students will learn how radioactive decay proceeds, and how to interpret data from isotopes found in rocks. A set of dice will represent a population of decaying atoms, and as students roll and remove dice from the parent population, they will see that as the parent population decreases and the daughter population increases that a standard set of ratios can be developed and used in studying the ages of rocks. I strongly recommend investing in a set of 400 6-sided die, but ther
