Topic in Depth - Radiometric DatingThere have been many modern scientific pushes to discover the age of natural and human-made artifacts and this folder describes some of them. Carbon-14 and Potassium Argon dating are just a few covered here in lesson plans, lectures, and overviews.
Radiometric Dating This site, created by Pamela J. W. Gore at Georgia Perimeter College, provides a concise explanation of the geologic principles of radiometric dating. Students can learn about the fundamentals of half lives, isotopes, and dating minerals. There are also descriptions of how Carbon-14 and Fission Track dating work.
Museum Victoria: Radiometric Dating The Museum Victoria offers a useful overview of radioactive decay of Potassium-40 and Carbon-14. The website discusses the benefits of isotopes for the research interests of geologists and physicists. There is also information about the dating capabilities of uranium, thorium, and ribidium.
Tulane University: Radiometric Dating The fourth website, developed by Professor Stephen A. Nelson at Tulane University, provides a detailed mathematical explanation of the principles of radiometric dating. The site is divided into sections which include: Principles of Radiometric Dating; The Rb/Sr System; The U, Th, Pb System; and The Age of the Earth. ...
Scottish Universities Environmental Research Centre This website describes the Scottish Universities Environmental Research Centre's work utilizing luminescence and radiocarbon dating. Through this expansive website, visitors can learn about the centre's many research projects including radioactive contamination, isotope geology, and environmental gamma spectrometry.
Countertop Chemistry Experiment 27: Radioactive Decay of Candium The North Carolina State University educational outreach program The Science House provides a fun, educational activity about radioactive isotope decay. Students can learn about the half lives of elements with the use of only candy, bags, and graph paper. There are six questions students are expected to answer or...
Nuclear Chemistry This page, from the University of North Carolina - Chapel Hill Chemistry Fundamentals program and the Shodor Education Foundation, discusses five different types of radioactive decay: alpha, beta negative, gamma, positron emission, and electron capture. After examining the numerous equations, students can test their...
Dating Techniques This website, part of the Department of Anthropology's E-Museum at Minnesota State University, describes more than 20 relative and absolute age dating techniques used by archaeologists. Users may manipulate an interactive seriation program to demonstrate how to date sites by occurrence of artifacts.
Relative Dating in Archaeology These two classroom exercises introduce students to stratigraphy and the law of superposition as well as seriation, dating techniques used by archaeologists to establish a relative chronology. They can be adapted to students at different levels using local materials. In the first exercise, dated materials such as...
