Biozones, stratigraphic log correlation, and corresponding interpretation of paleoenvironments.
Francis Jones, University of British Columbia
This exercise is a guided opportunity for any number of students (even hundreds) to start using recently learned, lower-level knowledge about stratigraphy and biostratigraphy in an integrative, interpretation ...
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 ...
The Cosmic Calendar
Erika Grundstrom, Vanderbilt University
In this activity, one takes ALL of time, from the beginning of time (i.e., the Big Bang) all the way up to today, but one compresses it into one year. One can do this for all levels of students depending on how ...
Metaphor for the geologic time scale
Students choose an object or concept that they are familiar with (e.g., football field, pint of beer, etc) and calculate the cumulative amount of that object or concept that represents intervals of geologic time. ...
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 ...
Radiometric Dating Isochron exercise
John Weber, Grand Valley State University
Hands-on introduction to using the isochron method to determine radiometric ages.
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 ...
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 ...
Hierarchical Alignment of Timelines
In the hierarchical alignment activity students progressively and hierarchically align scale information to a spatial linear representation. The progressive alignment of scales may alleviate the conceptual ...
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 ...
