Students use M&Ms to demonstrate the idea of radioactive decay. Parent isotopes are represented by the M side up (radioactive). Paul, MN, based on an original activity retrieved from also with the help of Jenni Johansen (other 8th grade science teacher at So. Paul Junior High School In this activity, students gain a better understanding of radioactive dating and half-lives.The emission of these rays is called nuclear radioactivity, or simply radioactivity. A nucleus that spontaneously destroys part of its mass to emit radiation is said to decay.A substance or object that emits nuclear radiation is said to be radioactive.Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs.

THANK YOU SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCH!!!!!!! I FINALLY UNDERSTOOD THIS BECAUSE OF THIS WEBSITE!!!They will only re shake the radioactive M&Ms each time. Once they are finished with their 8 runs, they will record their data on the class data table (which can be on the board).Once all groups data is on the table, you can calculate the average for each run (1-8) and determine a class average.Once all groups finish, each group records their info on the class decay table (on the board) and we calculate the averages of the class. Isotope Concepts: Students should begin to see the pattern that each time they dump out their M&Ms, about half become stable.Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives. Students will be able to explain what a half-life of a rock is. Students will have a more in-depth understanding of what radioactive decay is. Students will understand how scientists use half-lives to date the age of rocks. Students then should be able to see the connection of the M&Ms and radioactive elements in rocks, and how scientists can determine the age of rocks by looking at the amount of radioactive material in the rock.
