Fluvial and Alluvial Sedimentology Incorporating Google Earth part of Cutting Edge:Sedimentary Geology:Activities
A lab activity for an undergraduate sedimentary geology course focused on fluvial and alluvial sedimentology, incorporating Google Earth.
Red Beans and Rice: Slope failure experimental modeling part of Activities
Students replicate a slope failure experiment published in Science (Densmore et al., 1997) using a simple, acrylic slope failure box in an effort to forge a link between autocyclic processes, long-term landscape ...
Hometown Geology part of Cutting Edge:Introductory Courses:Activities
This is an extra credit assignment for students to learn details about the geology of their hometown.
Geomorphology in the news part of Activities
The activity requires students to present a current news story that has a geomorphic component. The students must relate course material to current events and society.
Rocks, Weathering, and Erosional Landscapes part of Activities
Students will identify a variety of silicate minerals and rocks and relate them to their topographic expression according to relative resistance.
Geo-Savvy Assessment part of Activities
I use this "landscape interpretation" exercise to assess what students know coming into my classroom - so that I can pitch the lecture at the right level. I also use a similar structured assessment at the ...
Drainage Basins Field Lab part of Activities
This field activity and follow-up assignment explores the geomorphology of drainage basins in an active tectonic setting. It introduces basic concepts of drainage basin structure and landscape analysis using ...
Humans as Geomorphic Agents part of Activities
An introduction to order-of-magnitude calculations and reading quantitative journal articles.
Teaching geologic time and rates of landscape evolution with dice part of Rates and Time:GSA Activity Posters
Landscape evolution provides a convenient framework for understanding geologic time and rates because students can observe how processes like erosion and deposition shape their surroundings. In this example, students build 3-D sandbox models based on topographic maps and design and stage a "virtual adventure race." Sandbox landscapes are used to illustrate erosional processes,while local examples are used to discuss landscapes as transient or steady over different time- and length scales. Dice experiments illustrate radioactive decay and the shape of the age equation curve, and 14C dating, geochronology and thermochronology are introduced as "stopwatches" that start when a plant dies, a crystal forms, or a rock nears the surface and cools to a certain temperature. The sandbox model and thermochronometer "stopwatches" are combined to measure erosion rates and rates of landscape change. Ultimately, model rates (cm/hour) calculated from stopwatch times on the order of seconds can be related to geologic rates (km/My) calculated from real million-year-old samples.
South Carolina Studies: Bringing the Geologic Time Scale Down to Earth in the Students' Backyard part of Rates and Time:GSA Activity Posters
Students visit Drayton Hall historic plantation near Charleston, South Carolina and are led on a field trip that starts with a discussion of documented historic changes that have affected the mansion and the surrounding property. The field trip continues with a study of Native American artifacts and ends with analysis of coastal plain deposits exposed along the Ashley River. Students use paleogeographic maps to discuss both historic and prehistoric changes to the landscape. Back in the classroom, students gather data to draw paleogeographic maps of their own school site through geologic time.
