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 ...

The new version of Ada explains how the age of objects can be determined by the rate at which objects decay radioactively. Ada demonstrates to the girls how to construct a half-life graph ...

For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. As this breakdown occurs, the activity of any radioactive source becomes less. This activity is measured in becquerels.
