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 ...
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.
Crater Counting Lab exercise
Kevin Mullins, Coconino County Community College
This lab is designed to teach students how we can estimate the age of other planetary surfaces by counting and size-binning impact craters. It also illustrates some examples of how erosional or deopositional ...
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 ...
Climate History from Deep Sea Sediments
DATA: Integrated Ocean Drilling Program (IODP) Core Data. TOOL: Virtual Ocean. SUMMARY: Locate potential core, log, and seismic data to map the marine sediment biostratigraphy. Search for a specific planktonic foraminifera that prefers warmer ocean conditions.

Fun with foam, demonstrating strike and dip in class
Angela Moore, Guilford College
Colorful foam sheets are used in a classroom or lab setting to introduce students to the concept of strike and dip. It is interactive, and the instructor or TA's can quickly see which students are ...
Ordering Geologic Events and Interpreting Geologic History: The Grand Canyon
Jennifer Wenner, University of Wisconsin-Oshkosh
This activity is designed to have students re-examine rocks they looked at earlier in the semester and use them to interpret some of the geologic history of the Grand Canyon.
Relative Time Application and Synthesis Exercise
David Steer, The University of Akron
This classroom activity is a formative assessment that explores the degree to which students can apply relative time principles and synthesize that information with concepts related to the rock cycle.
Relative Age-dating -- Discovery of Important Stratigraphic Principles
Roger Steinberg, Del Mar College
Students don't have to be passively taught the important principles geologists use to do relative age-dating of rocks and geologic events. By careful analysis and critical thinking about photos and ...
