Collaborative Research Project: Geoscience Undergraduate Curricula
Barbara Bekken, Virginia Polytechnic Institute and State Univ
Collaborative research project in which undergraduate geoscience curricula at Research 1 institutions are compared. This project uses the methods of science to explore a topic that beginning students can understand. This project uses rubrics for self, peer, and instructor assessment.
Exploring Evidence of Plate Tectonics Using GeoMapApp
Sean Cornell, Shippensburg University of Pennsylvania
This activity requires students to explore a range of datasets that help substantiate Plate Tectonic Theory. Students investigate plate tectonic environments (convergent, divergent, transform boundaries), topography/bathymetry of continents and ocean basins, the distribution and pattern of earthquakes, the distribution of volcanoes, as well as ages of the sea-floor, and more.
Investigating Stream Energy and Gradient Using Small Stream Tables
Beth Dushman, Del Mar College
In this Physical Geology lab activity, students investigate the relationship between stream energy and gradient by changing the gradient of a small stream table and observing changes in stream erosion.
Exploring the nature of geoscience using cartoon cards
Anne Egger, Central Washington University
In this activity, students work in groups to put a set of cartoon cards in order, much in the way that we might assemble a geologic history. The primary goal of the activity is to explore the nature of science in general and the nature of geoscience or historical science specifically, without requiring any content knowledge.
My Geologic Address: Locating Oneself in Geologic Time and Process
Kip Ault, Lewis & Clark College
Students locate their homes on local, regional, and global scale geologic maps. They build up an "address" describing their location in geological terms based on the features of the maps, from local bedrock to regional and global tectonic features.
Riparian Plant Lab
Julie Stoughton, University of Nevada-Reno
In this field exercise for an introductory environmental science course, students investigate plant cover and type in a riparian area using transects. The final assignment is a lab report that includes a summary data table, a graph of cover types along their transect and an analysis of riparian health.
Accuracy, Precision, and Topographic Data
Scott Linneman, Western Washington University
This jigsaw style exercise challenges new geomorphology students to collect topographic data and analyze its accuracy and precision.
Reasons for the Seasons
Jeff Thomas, Central Connecticut State University
The inquiry method and meteorological and astronomical online data can be used to elicit the inconsistencies of students' naïve ideas about the "real" reasons for the seasons. The first phase of this two-part investigation uses online meteorological data to identify factors that might explain differences of seasonal temperatures among cities These factors are used to hypothesize why differences of seasonal temperatures occur among cities. During the second phase, the variables and hypotheses that were previously identified in part one are used to design and conduct an inquiry-oriented investigation. Astronomical data is used as part of the investigation to "test" students' hypotheses— conclusions are drawn then communicated.
Calculating the radius of the Earth
Basil Tikoff, University of Wisconsin-Madison
Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.
Transport of heavy metals in the Clark Fork River
Kathleen Harper, University of Montana-Missoula, The
This is an activity about transport of sediment contaminated by copper, arsenic, and other heavy metals that was deposited into the Clark Fork River channel as the result of historical mining activity. The Clark Fork River between Butte and Milltown, Montana has been the focus of several large superfund projects designed to address the impacts of this legacy of mining in the watershed. This activity is used in an introductory physical geology lab (primarily non-majors) with students who may have limited experience working with quantitative analysis and analyzing graphs.
