Compare and discuss graphs for different isotopes. How are the curves similar and different? What do the curves suggest about the rate of radioactive decay in general? Groups can challenge each ...

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 ...

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.
