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

Let's TACO-bout: Sets, Relations and Functions
Intro to proof writing courses are based on a study of formal logic that must be abstract enough to apply to many subjects, but also stay grounded enough for students to understand. For this project, I used graphic design techniques along with the psychology of learning to create images that will increase the understanding of sets and relations. By using a fun overarching metaphor, tacos and a taco bar, it’s easier to see the relationship between these more abstract concepts. Many ideas in this
