Determining the Age of Rocks and Fossils, University of California, Berkeley. This 9-12-grade activity introduces students to age dating with exercises using relative and absolute dating. Links to various activities and lesson plans concerning relative and absolute dating. Content information about absolute and relative dating methods used by the U. Larger-than-life concepts such as prehistoric time, half-life properties and decay functions can be wrestled down to understandable portions using lesson plans provided by educational and state agencies for free online.
Yet, you’ve heard the news: Earth is 4.6 billion years old. That corn cob found in an ancient Native American fire pit is 1,000 years old. Geologic age dating—assigning an age to materials—is an entire discipline of its own.
This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.
The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.
The site also provides fact sheets on the age of the Earth and isochron dating.
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
