The first website (1), 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. Secondly, the Museum Victoria offers a useful overview of radioactive decay of Potassium-40 and Carbon-14 (2). The website discusses the benefits of isotopes for the research interests of geologists and physicists. Next, Dr. Ben Waggoner at the University of Central Arkansas provides an online educational slide show discussing the assumptions, objections, and accuracy of radiometric dating (3). With an abundance of figures and images, visitors can learn about dateable materials, decay principles, and more. The fourth website, developed by Professor Stephen A. Nelson at Tulane University, provides a detailed mathematical explanation of the principles of radiometric dating (4). Users can view the data utilized for the corrections and can access the on-line form of CALIB, which converts radiocarbon ages to calendar years. The sixth website describes the Scottish Universities Research and Reactor Centre's work utilizing luminescence and radiocarbon dating (6). Through this expansive website, visitors can learn about the centre's many research projects including radioactive contamination, isotope geology, and environmental gamma spectrometry. Next, the North Carolina State University provides a fun, educational activity about radioactive isotope decay (7). Students can learn about the half lives of elements with the use of only candy, bags, and graph paper. Lastly, the University of North Carolina - Chapel Hill chemistry department discusses five different types of radioactive decay (8). After examining the numerous equations, students can test their dating skills by solving the practice problems.
