In this activity, students gain a better understanding of radioactive dating and half-lives. Parent isotopes are represented by the M side up radioactive. Daughter isotopes are represented by the M side down stable. They then set aside stable isotopes During each trial, students record the number of radioactive parent isotopes and record this in a data table.

Principles of Radiometric Dating
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.
