Developing ethical and privacy sensitivity towards geocoded data
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This case study is intended to develop an awareness of the ethical and privacy implications for the creation, sharing, interpretation, and use of geocoded data, that is, data with locational content. It provides a set of relevant ethical and legal standards, along with a fact-rich hypothetical. By applying those standards to the hypothetical, learners from a variety of backgrounds are offered the opportunity to develop an awareness of the potential for unintended and negative consequences to result from geocoded data practices that appear, in isolation, to be unproblematic.

Developing student literacy on risk, resilience, and strategies for living with disaster uncertainty
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this guided research and critical thinking activity, students prepare a research paper comprised of two parts: 1) a "state-of-the-science" review and synthesis of selected literature from risk and resilience research (provided) and 2) a brief critical appraisal of how current knowledge is (or could be) applied to building disaster resilience in a real-world scenario. Part 2 will be set in a student-selected hazard context (coastal hazards, flooding, or earthquake), employment sector (academia, government, private industry, services, non-profit), and geopolitical sphere of influence (e.g., Resilience to earthquake disaster in the student population at Universidad de Lima, Peru).

Development of a Syllabus for Environmental Issues course
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

We introduced a new required course "EnSc 210: Issues in Environmental Science" for our majors about three years ago. When I was assigned to teach this course for the first time, I struggled with developing a syllabus and recommending a text for the course. Since we also offer classes in "Environmental Geology" and an introductory course "EnSc 110 Understanding the Earth," the challenge was to avoid duplication while developing an appropriate syllabus. What I finally decided to do was to have students provide ideas. So, on the first day of class I announced that we don't have a syllabus for this course (many sighs of disappointment) and, after a brief remark on some current environmental issues, invited each student to suggest at least one topic for inclusion in the course. After some hesitation (as expected) hands went up and I began writing each topic on the white board. Pretty soon we had 20-25 topics with some overlapping themes. Some of these included: population problem, global climate change, air and water pollution, waste management, environmental health, species decline, environmental impact of large dams, and sustainability. After some discussions about relative importance of various topics and the time available to cover each during the semester, we narrowed it down to about 10 topics for detailed study. I prepared my syllabus (linked below) based on this list which worked very well because: we were able to include key topics and, very importantly, students felt a sense of 'ownership' which led to a very interesting and interactive class experience throughout the semester.

Devonian Transformation
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

To complete this assignement student have to work in groups to answer a series of questions on the evolution of land plants. They need to combine material previously covered in lecture and information from the WWW to determine how the evolution of land plants changed the lithosphere, atmophere, and biosphere.

After completing the attached exercise the students participate in a guided discussion. There are several way to divide students up into groups.

Different groups are asked to summarize: the link between the spread of land plants and

1) atmospheric carbon levels and climatic conditions,

2) organic carbon and dissolved oxygen levels in the ocean

3) the abundance of corals and other marine animals: shallow vs. deep ocean

4) Erosion rates on land and rates of organic matter burial in the oceans.

5) General patterns in diversity and biomass of marine and terrestrial fauna

Then each group is asked to discuss how the aspect they considered about the Devonian Extinction fits into and differs from conditions we see in the modern carbon cycle.

Diagnosing Landslide Hazard
Conditional Remix & Share Permitted

Rating
0.0 stars

Landslide between Highway 7 and the Susquehanna River (42.4947º N, 74.98212º W). Although, this exercise may be adapted elsewhere. An active, large active hillslope is required, preferably one close to infrastructure, and one which students can access safely. The following features are not uncommon, and make the problem richer: a river bend at the toe of the hillslope; a gas or water line routed through the slide; a hillslope exhibiting numerous scales of movements, from small debris flows a few cm wide to large rotational slides; and nearby infrastructure, such as buildings or roads.

Did Early Farmers Alter Climate?
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The overarching goal of this exercise is for students to explore the early anthropogenic hypothesis, which claims that early agriculture had a substantial impact on greenhouse gases and global climate thousands of years ago (Ruddiman, 2003). Students compare changes in greenhouse gas concentrations that occurred thousands of years ago to more recent changes that occurred over hundreds of years. Students also relate changes in greenhouse gas concentrations to warming. The exercise is completed over a 1.5- to 2-week period as the class covers a chapter on climate change.

Did it Rain on Mars? Analysis of Valley Networks on Mars in an Intro Geo Course
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Some of the Viking images sent back from Mars in the 1970s show tantalizing evidence of dendritic valley networks in some of the oldest terrains on the planet. One of the big questions ever since has been whether it might have rained early in Mars history.

One of the ways of deciding whether the Mars valley networks might have been produced by rainfall is to find out how similar they are to valley networks on Earth, which we know are produced by rainfall. The standard method for analyzing drainage basins is comparison of the number of drainage segments per square kilometer (drainage density) and how extensively branched the network is (stream order).

In this exercise, students calculate stream order for valley segments mapped by Hynek and Phillips (2003) using MOC/MOLA data. Students then use data on valley segment length and drainage basin area from Hynek and Phillips (2003) to calculate drainage density. They compare stream order and drainage density for the Mars site with similar calculations for areas on Earth and evaluate the question of whether valley networks on Mars might be consistent with rainfall on an early Mars, and what the uncertainties and limitations are in their conclusions.

Digital Sandstone Tutorial
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

An understanding of the microscale structure and composition of sedimentary rocks is of undiminished importance in diverse fields (e.g., microscale chemical analysis cannot proceed without petrography), yet the curriculum is no longer offering undergraduates the opportunity to develop sufficient expertise. In an effort to bolster the exposure of undergraduates to sedimentary petrology, the Tutorial Petrographic Image Atlas was created. The basic components of the tutorial are petrographic images that are viewed in a static mode (no rotation, no animation, no timed observation). Text boxes relating to identification of components within the image are attached to specific mapped regions of the image. Both the mapped regions and the text are invisible until the student points and clicks on an active region of the image. In essence, the student must 'ask', "What is that?" Information ranges from simple one word identifications to lengthy paragraphs explaining the finer points of why something is what it is.

This is a highly interactive digital product that attempts to recreate certain elements of the laboratory petrographic experience including: a sense of exploration; high-quality petrographic images; a visual field dominated by the image; multiple examples of features viewed in diverse contexts; rich content relating to the identification and significance of features; active, inquiry-based learning.

Unlike real-time laboratory experiences with the petrographic microscope, the digital tutorial can be used at any time and place that a computer is available, does not require the presence of a microscope or samples or an expert, can be viewed repeatedly, has the technical content integrated with the image, gives the student undivided "attention" (unlike the TA, it doesn't wander to the other side of the lab), and rarely gives answers unless "asked."

Digitization and Volumetric Analysis of Sediment Transport in a Simplistic Flume
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The activity is designed to help students conceptualize the spatiotemporal relationships between erosion and deposition across a convex topography, which serves as a proxy for understanding rill and gully formation, knickpoint migration, valley excavation, and the interplay between sediment supply and accommodation across distributary features. The exercise utilizes simplistic flume observations and measurements to generate digital terrain models (DTMs) of generated topographies; by changing individual flume parameters between experimental runs (such as discharge, slope, and sediment type and moisture content), students are able to determine controls on sediment dispersion.

This is an online learning experience that transports learners around the world to different locations related to the Cretaceous -- Paleogene (K -- Pg) extinction event. Students will collect and analyze evidence to explain how natural events impact life on Earth.
The KPg extinction event, which occurred 66 mya, caused the mass extinction of nearly 75% of the plant and animal species on Earth, including the dinosaurs. It is marked by a thin layer of sediment which can be found throughout the world in marine and terrestrial rocks.
