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

Molecule Madness - Activation Energy
This game explores Activation Energy—the minimum energy needed for molecules to collide and react, much like the force needed to strike a match. Think of it as pushing a boulder over a hill: once pushed far enough, it rolls down, and the reaction occurs. Activation energy is the potential energy needed for molecules to reach the point of interaction, often supplied by heat through increased collisions. In this lesson, students physically model the chemistry concept of activation energy by playin
