Carbon-14    • Teacher Resource   • Posted 08.09.12   • NOVA  In
this video excerpt from NOVA's "Hunting the Elements," New York
Times technology columnist David Pogue explores how isotopes of
carbon can be used to determine the age of once-living matter.
Learn how variations in atomic structure form isotopes of an
element and how the three natural isotopes of carbon differ from
each other. Meet paleoclimatologist Scott Stine, who uses
radiocarbon dating to study changes in climate. Find out what it
means for an isotope to be radioactive and how the half-life of
carbon-14 allows scientists to date organic materials.
