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 ...
Geologic Puzzles: Morrison Formation
Heather Macdonald, College of William and Mary
Images of faulted strata, tilted turbidites, and beach rocks bring the field into the classroom, giving students practice in doing what geoscientists do. These images are examples of geologic puzzles. -
Relative Dating on Earth and Mars
Sara Harris, University of British Columbia
Students apply principles of relative dating to a cross-section, then to the surface of Mars.
Physical Geology: Idaho Field Trip
Simon Kattenhorn, University of Idaho
Optional field trip to local sites of geologic interest/relevance.
Seafloor Ages Lecture Tutorial
Karen Kortz, Community College of Rhode Island
Students work on this Lecture Tutorial worksheet on seafloor ages in pairs during lecture. It directly confronts misconceptions students have about the age of the seafloor, and it guides students to more complex ...
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.
