Exemplary Teaching Activities
Beginning in 2011, On the Cutting Edge began a process to review the extensive collection of activities submitted by workshop participants and members of the geoscience community. The Review Processes page illuminates the details of the peer review process, and the activities are scored on 5 elements: scientific veracity; alignment of goals, activity, and assessment; pedagogical effectiveness; robustness; and completeness of the ActivitySheet. The activities that score very highly in these areas become part of the Cutting Edge Exemplary Collection and are featured below. To date, activities in the mineralogy, petrology, geochemistry, environmental geology, structural geology, geophysics, and tectonics areas have been reviewed so the exemplary collection is composed of activities from these topics. As the review of additional areas is completed, exemplary activities from the rest of the collection will be included here.

Comparing Carbon Calculators part of Starting Point-Teaching Entry Level Geoscience:Teaching with Data:Examples
Mark McCaffrey, National Center for Science Education
Carbon calculators, no matter how well intended as tools to help measure energy footprints, tend to be black boxes and can produce wildly different results, depending on the calculations used to weigh various ...
How Effective is a Remediation System at a Regional Landfill? part of Geochemistry:Activities
Kevin Theissen, University of St. Thomas (MN)
In this activity, students begin exploring the effectiveness of a remediation system installed at a closed landfill system. Students learn the importance of redox chemistry in a real-world context and build field ...
Course Information Survey part of Online Teaching:Activities for Teaching Online
Donald Reed, San Jose State University
This activity is a brief quiz to be completed at beginning of course that provides information to instructor about the internet access and computer resources of each student as well as assesses whether student has ...
Analyzing Continuous Data - Climate Variability part of Early Career:Previous Workshops:Workshop 2011:Teaching Activities
Sarah Rubinfeld, Carthage College
The exercise focuses on the analysis of continuous data as applied to climate variability. Using data freely available on the internet, students work in Excel to import their data, organize it, and analyze it using ...
M & M Decay part of Rates and Time:Teaching Activities
Rebecca Teed, Wright State University-Main Campus
This is a simulation of radioactive decay which illustrates what a half-life is and explains some of the challenges involved with radiometric dating. Pennies or other cheap coins can be substituted for M&Ms if ...
Determining Earthquake Recurrence Intervals from Trench Logs part of Rates and Time:GSA Activity Posters
Patricia Cashman, University of Nevada-Reno
Trench logs of the San Andreas Fault at Pallett Creek, CA are the data base for a lab or homework assignment that teaches about relative dating, radiometric dating, fault recurrence intervals and the reasons for uncertainty in predicting geologic phenomena. Students are given a trench log that includes several fault strands and dated stratigraphic horizons. They estimate the times of faulting based on bracketing ages of faulted and unfaulted strata. They compile a table with the faulting events from the trench log and additional events recognized in nearby trenches, then calculate maximum, minimum and average earthquake recurrence intervals for the San Andreas Fault in this area. They conclude by making their own prediction for the timing of the next earthquake.
Roping Geologic Time part of Rates and Time:GSA Activity Posters
Randall Richardson, The University of Arizona
After having talked about the geologic time scale, I ask for two volunteers from the class to hold a rope that is 50 feet long. I say that one end is the beginning of the Earth (4.6 billion years ago), and the other is today. I then give out 16 clothes pins and ask various students to put a cloths pin on the 'time line' at various 'geologic events'. Throughout the activity I have a quiz going on where the students calculate percentages of Earth History for major geologic events, and compare it to their own ages. On their time scale, the dinosaurs died only about two 'months' ago! The exercise is very effective at letting them get a sense of how long geologic time is, and how 'recently' some major geologic events happened when you consider a time scale that is the age of the earth.
The Evolution of Earth through Time part of Rates and Time:Teaching Activities
Phil Stokes, The University of Arizona
This activity is designed for large freshman courses (>200 students) and is used in-class. The activity requires a short (15 minute) overview of Earth history before students have the opportunity to work through ...
Hierarchical Alignment of Timelines part of Rates and Time:Teaching Activities
ilyse resnick, Temple University
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 ...
Bedrock Geology Mapping Exercise part of Geoscience in the Field:Activities
Jim Miller, University of Minnesota-Duluth
As a final exercise in a course on Geological Maps, students conduct a field mapping of a one square mile area over a weekend. Back in the classroom, students are introduced to ArcMAP and Illustrator, with which ...
