Accelerator Mass Spectrometry AMS dating involves accelerating ions to extraordinarily high kinetic energies followed by mass analysis. The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.

Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination. Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.
Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination. Daughter isotopes are represented by the M side down stable.
They then set aside stable isotopes During each trial, students record the number of radioactive parent isotopes and record this in a data table. Once all groups finish, each group records their info on the class decay table on the board and we calculate the averages of the class. Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives.
Classroom Activity Grade Level: Material on this page is offered under a Creative Commons license unless otherwise noted below. Paul, MN, based on an original activity retrieved from http: Paul Junior High School. Summary In this activity, students gain a better understanding of radioactive dating and half-lives.
Students will be able to explain what a half-life of a rock is.

Students will have a more in-depth understanding of what radioactive decay is. Students will understand how scientists use half-lives to date the age of rocks. This activity can be adapted for older students, but is used in an 8th grade earth science classroom. Class size can vary, but activity should be done in groups of Students should have the skill to set up a data table and a graph, however, if you want to use this activity with students that have not, you can provide them a template with that information.
As far as mastery of content, this activity is done in our rocks and minerals unit. Students should have some prior knowledge of rocks and how they are dated. This activity would also be easy to adapt when talking about half-lives within a chemistry course. New information needed to be introduced with parent and daughter isotopes. Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs.
