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 ...
Teaching radioactive decay & radiometric dating: an analog activity based on fluid dynamics
Erika Grundstrom, Vanderbilt University
Radiometric dating/geochronology is a difficult concept for students. Using the (rather messy) medium of shampoo, students watch it flow through holes of different sizes, determine the exponential decay equation, ...
Radiometric Dating Isochron exercise
John Weber, Grand Valley State University
Hands-on introduction to using the isochron method to determine radiometric ages.
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 ...
Relative Age Correlation
Gwen Daley, Winthrop University
Students learn to apply basic correlation principles to geologic cross-sections.
Time Scales of Climate Change
Erika Grundstrom, Vanderbilt University; Cara Thompson, Santa Monica College; maya elrick, University of New Mexico-Main Campus
This activity introduces students to the fact that climate change occurs at timescales of 1 year to 108 years and there are various drivers to explain these changes. It addresses how scientists detect these scales ...
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 ...
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 ...
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 ...
