Students examine actual radioactive decay data collected in an honors chemistry class to find an equation which best fits the data and allows a person to predict the count after certain periods of time have elapsed. Students review all...

Determine the decay constant and half-life of an isotope based on the activity data of the isotope as a function of time.

This set of activities from the Milton J. Rubenstein Museum of Science & Technology has students investigating how relative dating and absolute dating methods are used to determine the age of rocks and fossils.
