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.An example natural selection activity lets students mimic bacteria becoming immune to antibiotics.Evolution worksheets and exam / test / quiz questions also provide help with evaluating the student’s progress.

American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.
He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.
