Radiometric Dating Isochron exercise
John Weber, Grand Valley State University
Hands-on introduction to using the isochron method to determine radiometric ages.

Drawing unconformities
Gina Szablewski, University of Wisconsin-Milwaukee
Thess simple sketches are used in class to show the development of different unconformities.

Greenstone Belt Assessment
Pamela Nelson, Glendale Community College
Students examine and describe rocks found as part of a geologic sequence formed during the Precambrian Era and determine the geologic significance of each of the rocks in order. The capstone (not included on the ...

Geologic Time Discussion Analogies
Noah Fay, Pima Community College
This is 4 ppt slides used to facilitate discussion w/students about the immensity of geologic time. I ask them a series of leading questions and try to get them to do "mental math" in order to grasp the ...

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 ...

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 ...

Depositional Environments and Geologic History Labs
Maria Waller, Wellesley College; Kathy Gilbert, Wellesley College
This is a pair of labs that incrementally prepare students to interpret the geologic history of a rock sequence. The first lab introduces students to depositional environments and fossils. The second lab presents a ...

Relative vs. Numerical Dating and Geochronology with Beads
Karen Viskupic, Boise State University
Students use relative dating principles to interpret the ages of rocks in a block diagram. They then "date" samples from these rocks to test their relative age hypotheses. Sample dating is done by ...

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 ...

Relative Age Correlation
Gwen Daley, Winthrop University
Students learn to apply basic correlation principles to geologic cross-sections.
