Driving question : How to model radioactive decay?
In this activity students explore radioactive decay via a given decay model. Based on the model they determine the function, which describes the radioactive decay. Further they modify the model to describe a decay of a real radioactive isotope e.g. Barium 137m and compare how well the model fits the experimental results.
