This document provides instructions for a lab on radioactive decay. Students are told to get their lab notebook and binder, write the title of the lab, and provide a three sentence introduction defining isotopes, radioactive isotopes, and half life. They are then instructed to copy the materials list and procedures into their notebook and set up a blank data table to record results. Finally, students are to answer discussion questions in full sentences.
