Numerical Time (Candy & Radioactive decay)

Source/Author: David McConnell, Jennifer Wiggen
Subject: How we figure out how old rocks are
Description: This video discusses how geoscientists use information from the radioactive decay of isotopes to establish the age of geologic events. We explain what isotopes are, how they undergo radioactive decay and how to figure out the number of half-lives they have experienced to establish when they formed. We use candy to model the decay process and to make it easier to visualize the process of decay.
