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.

Analysis of Sidewalk Fractures part of Structural Geology:Activities
Using fractures in sidewalks as an analog for natural outcrops, students learn to make systematic observations, measure the orientation and location of fractures, manipulate and analyze data, and consider some ...

Borehole analysis using stereographic projection part of Structural Geology:Activities
Advanced stereonet project using unoriented core structural data. The project gives practice in plotting small circles and in rotations. -

Metamorphism of siliceous dolostone: An example from the Alta stock, Utah part of Petrology:Teaching Examples
In this exercise students study the low variance mineral assemblages from the contact aureole of the Alta stock to learn how rock and fluid compositions control mineral assemblages during contact metamorphism.

Evolution of Normal Fault Systems During Progressive Deformation part of Structural Geology:Activities
This activity is based on QuickTime movies and color digital photographs derived from sandbox experiments that produce normal faults in a variety of boundary conditions following experiments developed by Ken ...

Seattle Flooding part of Quantitative Skills:Activity Collection
An activity/lab where students determine the changes in 100-year flood determinations for 2 streams over time.

Igneous Rock Compositions and Plate Tectonics part of Petrology:Teaching Examples
In this exercise, students use whole-rock major- and trace-element compositions of igneous rocks from a variety of tectonic settings and locations to explore the importance of plate setting in determining magma ...

Campus Greenhouse Gas Emissions Inventory part of Starting Point-Teaching Entry Level Geoscience:Campus-Based Learning:Examples
Students conduct a greenhouse gas emission inventory for their college or university. Students analyze findings and present information to the college or university community. -

Discovering Plate Boundaries part of NAGT:Teaching Resources:Teaching Materials Collection
Students work collaboratively using data maps to discover plate tectonic boundary processes. Data sets used are earthquakes, volcanos, seafloor age, and topography.

Mass Balance and Mineral Reactions part of Petrology:Teaching Examples
This is a short exercise to make sure that students understand mass balance and how the different starting assemblages may lead to different results after metamorphism. It is quick but not trivial.

Water Wars: A look at Gallatin Valley Water Controversies part of Public Policy:Activities
This virtual field trip explores the science and policy of a ground water dispute in Gallatin Valley Montana. The virtual field trip uses a role-playing activity to explore the geology, hydrology and policy related ...
