Geologic and Navajo Time Line
Margaret Mayer, Dine College
Students develop a time line using registrar tape and correlating marking off divisions of geologic eras. Above this they develop a Navajo time line of creation. Each week they focusing on the topic (era/period) of ...

Using Dendrochronology to Determine the Age and Past Environments of the Black Forest Region, Colorado, USA
Paul Grogger, University of Colorado at Colorado Springs
The use of dendrochronology in determining the geologic history of a location. The development of an understanding how tree growth can indicate the relationships between climate, geomorphology, ecology and archeology.

Radiocarbon dating project
Mark Schmitz, Boise State University
This is an example of an activity used in a Quaternary Geochronology course, in which a small group of students (3-4) is tasked with transforming a set of activity measurements into radiocarbon ages and calibrated ...

Determining Earthquake Recurrence Intervals from Trench Logs
Patricia Cashman, University of Nevada-Reno
Trench logs of the San Andreas Fault at Pallett Creek, CA are the data base for a lab or homework assignment that teaches about relative dating, radiometric dating, fault recurrence intervals and the reasons for uncertainty in predicting geologic phenomena. Students are given a trench log that includes several fault strands and dated stratigraphic horizons. They estimate the times of faulting based on bracketing ages of faulted and unfaulted strata. They compile a table with the faulting events from the trench log and additional events recognized in nearby trenches, then calculate maximum, minimum and average earthquake recurrence intervals for the San Andreas Fault in this area. They conclude by making their own prediction for the timing of the next earthquake.

Dating Students: Relative vs. Numerical Time
Susan Zimmerman, Lawrence Livermore National Laboratory
This activity introduces students to the fundamental ideas of relative versus radiometric dating, using the students themselves as a sample population. In the first half, the students attempt to order the people in ...

Quantitative Classroom Exercises
Steven Schafersman, University of Texas of the Permian Basin, The
The four exercises give students an opportunity to use their knowledge of graphs, algebra, and maps to solve simple geological problems.

Faint Young Sun, Radiocarbon dating
Mea Cook, Williams College
This problem set follows lectures and readings on (1) the Stefan-Boltzmann equation and the greenhouse effect in an n-layer atmosphere and (2) radiometric dating. The goal is for the students to apply equations ...

Proposing Questions for the Upcoming Midterm Exam
Leslie Gertsch, Missouri University of Science and Technology
This in-class activity involves groups of 2-3 students who review assigned sections of course material to generate exam questions (including answers), in one of several assigned formats. They then trade results and ...

Living with Volcanoes: An Introduction to Geoarchaeology
Alison Jolley, University of Canterbury
This activity introduces students to the interdisciplinary field of geoarchaeology through a case study of the eruption of Mt. Vesuvius in 79 CE. It combines short lectures with questions requiring analyses of a ...

Cyclostratigraphy and astrochronology exercise
maya elrick, University of New Mexico-Main Campus
Simple classroom activity to highlight how cyclostratigraphy and concepts of astronchronology can be used to refine age control in sedimentary rocks, estimate rates of processes, and for time control and ...
