In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may make all the difference. When you purchase through links on our site, we ...

Radiometric dating, utilizing the predictable decay rates of radioactive isotopes within rocks and other materials, is the primary method for determining the age of geological samples. Multiple ...
