Teaching Radioactive Decay: Radioactive Half-life And Dating Techniques
High schoolers generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

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 activity is repeated with remaining kernels, gathered data will illuminate the nature of half-life and decay rate.

Radioactive Decay Chains
After introducing your class to radioactive decay and walking them through the changes in the numbers of atomic particles, give them an opportunity to write equations for the first six daughters in a Uranium-238 decay chain. They also discover how eventually a stable element is formed.

Math in Science-Radioactive Decay and Half-Life
In this radioactive decay and half-life worksheet, students use given half-lifes to calculate the amount of time it will take for certain amounts of elements to decay. They also find the age of samples and determine how many grams of samples will remain in a given amount of time.

Radioactive Decay and Half-Life
Students describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is accomplished using pennies to represent isotopes.

Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms. The green beads are placed in one cup and the white beads in another.

Mmmmm! Radioactive "candium!" Nuclear physics or chemistry classes use M&M'S® to demonstrate the process of radioactive decay. Individuals pour out a bag of candies and record the number that fall M-side-up to represent the number of atoms that have decayed.

Students explore radioactive decay. Through various activities, students examine methods for permanent disposal of radioactive waste. After performing a random process experiment, students compare the results to radioactive decay. They answer discussion questions regarding a demonstration of of material.

Submarines and Aircraft Carriers: The Science of Nuclear Power
As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission, gamma rays, critical mass, and exponential decay.
