Nuclear Popcorn
Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...
Curated OER
Radioactive Decay Curve
Students gather and organize data. In this radioactive decay curve lesson plan, students gather data as they follow the provided procedures for rolling dice. Students chart their data and examine interval results.

Get a Half-Life!: Student Worksheet
In this math/science worksheet, students will work in pairs to conduct an experiment based on a decay function which is often used to model radioactive decay. Students will shake M & M's in a cup to rub off the M and then record...

Accuracy of Carbon 14 Dating II
The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

Worksheet #6, Exponents, Interest, and Radioactive Decay of Isotopes
In this calculus worksheet, students sketch graphs of given exponential functions. They compute the principal needed to have a given ending balance when the interest is compounded at varying times. Students use a simple exponential model...

Earth's Age: The Dating Game
Learners conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...
Curated OER
Get a Half Life!
Eighth graders use M&M's to experiment with data. They use a graphing calculator to determine the best equation for their data; linear, quadratic or exponential. They analyze the data to find the half-life of their M&M's.
