Originally a footprint was exactly what you might imagine - the print made by a foot.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.Basic understanding of how radiometric dating works is useful. This lesson is highly simplified, and the powerpoint describes everything the student will need to know for the activity.
