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.

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.

Aquifer Elasticity and Specific Storage part of Hydrogeology:Activities
The goal of this experiment is to measure the specific storage Ss of a balloon, which simulates aquifer elasticity. The experiment is designed to give observational meaning to the variable, increment of fluid ...

Quantifying Groundwater Baseflow and Improving Math Skills through a Stream-Discharge Exercise part of Hydrogeology:Activities
A two-part exercise is presented where students quantify stream discharge and use the data to determine groundwater baseflow. They first use tedious hand calculations to compute discharge; then develop their own ...

Pathogenic Microorganisms in Water part of Hydrogeology:Activities
This activity introduces students to sampling and testing for microorganisms in different water sources. It also tests iodine tablets to kill coliform bacteria which interest many students. The activity utilizes ...

Save Crooked Creek! Remediation of a Service Station Site with a Leaking UST part of Hydrogeology:Activities
The student group (3 to 4 persons) is given information regarding a leaking UST at a gasoline station in western Pennsylvania; a page detailing the history of the problem and a small sketch map if the site. They ...

Using Wetlands to Teach Hydrogeology part of Hydrogeology:Activities
Field exercises (surface-water, vadose-zone, and groundwater hydrology), in which students generate their own data throughout the semester, are presented for teaching hydrogeological concepts, techniques, and ...

Using Visual MODFLOW to Simulate Groundwater Flow and Transport part of Hydrogeology:Activities
Investigate the Dupuit Approximation to describe groundwater flow in an unconfined aquifer, using a computer spreadsheet program and Visual MODFLOW (Waterloo Hydrogeologic, Inc.). The major strength of this ...

Dye Trace Experiment using "Aerial" Imagery part of Hydrogeology:Activities
This exercise allows students monitor a dye plume in a stream using digital images collected by "remote aerial tramway".
