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.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives.Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs.Students will record the number of M&Ms that are still "radioactive" (M side up) in their data table after each run, and set aside the "stable" (M side down) M&Ms.They not only enjoyed this activity, but they really gained a better understanding of it as well.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
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.
