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 ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...
