Demonstrating the Half-Life of a Radioactive Isotope

In this half-life worksheet, students use 100 pennies to simulate radioactive isotopes and half-life. They place the pennies in a box and shake the box. All pennies that turn up tails are removed from the box. They represent the isotopes that have decayed. They answer questions about the lab once they are left with one penny.

I am a very busy Head of Department and often don't have time to create worksheets and other resources for my classes. Lesson Planet has helped me find many useful and interesting activities to support my students' learning.
