Students collect and analyze geological and biological materials for carbon content in order to investigate carbon through time. Implications for energy production now and in the future are explored in the context of carbon cycling in the oceans, the atmosphere, and the geosphere.

In this assignment, students in small groups are asked to interpret and explain a figure depicting one aspect of marine carbon biogeochemistry. Then a representative of each group explains the figure to the class.

The goal of this activity is for both me and the students to learn how well prepared they are for the mid term. In Wednesday's class I tell them we will be doing an assessment on Friday. For Friday I prepare a series of questions that cover the likely content of the mid term and print them out in large print, attaching them to self adhesive poster paper. I paste these up around the classroom and randomly break the class into teams of 3-5. Each team works on "their" question for ~8 minutes, answering the questions on the poster paper and adding what they are puzzled about. The each team moves to the next question/poster and works 3-5 minutes on it, absorbing what has been written and adding their own ideas and questions. The carousel continues to rotate every ~5 minutes until the teams arrive back at their original poster. Each team reads what has been written and prepares a summary. At this point the teams clarify items they do not understand. Monday's assignment for each team is to come to class with a better hand drawn poster and report to the class, answering some of the unanswered questions from Friday.

In the first part of the exercise, students examine a variety of ArcMaps to work out what data sets and techniques were used and to develop a list of the characteristics of effective, attractive, and complete maps. In part 2, students explore a GIS tutorial of cartographic techniques. You might also be interested in our Full GIS course with links to all assignments.

This activity promotes the learning of basic physics principle by viewing cartoon videos where these principles are bent of broken.

This multi-term assignment introduces students to local indigenous stories, significant plants and animals of our region and some basic skills in reading animal tracks and signs.

I designed this activity as a role-playing game to help students understand both the concept of climate modeling and how the climate system works. Students take on the role of a climate system component, examining their personal reactions to climate stimuli and building a future scenario based on their group's reactions. You can implement this teaching collection as part of the Climate of Change InTeGrate Module, Unit 5, or as a stand-alone activity.

In this activity, students consider how several communities are adapting to climate change-related problems including drought's impacts on agriculture, loss of assets due to climate-related hazards, freshwater availability, and extreme heat waves. They will read brief case studies about agro-forestry, insurance strategies, the "Room for the River" program in the Netherlands, water storage from retreating glaciers, and city planning for heat waves. Based on these examples and knowledge of their own community, they will suggest possible adaptation strategies that will be most beneficial to their area.

This ocean activity is used to help students analyze different solutions to a real-world case study of the problem of using various coastal stabilization structures. It is intended to be used as a small group activity (3-5 students in each group) following a short introductory lecture about coastal processes (especially longshore drift) and the different types of coastal stabilization structures (jetties, groins, and breakwaters). At the end of the activity, successful students will be able to critically evaluate the benefits and drawbacks of various types of coastal stabilization structures.

A case-study approach can be used to introduce students to the work that geologists do as environmental consultants. Data used by environmental consultants for a Brownfield site that is currently undergoing redevelopment in St. Paul, MN has been adapted for in-class study, either as a series of short exercises, or as part of a larger project.

This is a 'citizen science' research project where students to apply their knowledge of landslide processes in an investigation of the natural and anthropogenic causes of a real-world landslide catastrophe. Students produce a 'magazine' article discussing the Zhouqu, China, August 8, 2010 landslide catastrophe.

Students start this exercise using topographic maps of an area recently visited on a field trip to calculate and consider stream gradient of a major river south of Buffalo, NY. The activity then changes gears to have students work with discharge measurements from this stream. They use these measurements to plot and evaluate a few hydrographs which are used to compare how discharge in this stream can be used to consider how much precipitation was received in a certain year. In this lab, students practice mathematically calculating geomorphic properties of a stream, plotting data, and comparing topographic maps to what they observed on the recent field trip.

Two or three weeks of the course are dedicated to studying diagenesis. Lectures start with a general definition of diagenesis, the range of conditions under which it occurs, and examples of diverse diagenetic environments and features. I use rice crispy cereal and rice crispy treats to introduce cement (the marshmellow is the cement that "glues" the rice krispies together). I also incorporate basic hydrogeology to show how pores filled with (or partially filled with) groundwater provide both the space and the material for cementation. As part of this lecture, I show the students various rock samples and photomicrographs in which they can see cement examples. I outline the different cement minerals and shapes and how they can be used to interpret past diagenetic conditions (eg., gravitational "pendant" calcite cements indicate that the host sediment was once in a vadose zone with groundwater rich in calcium and carbonate). I also discuss types of pores during these lectures and the ways that pores form. We also discuss criteria for recognizing cements. After two one-hour lectures about cements, we have a lab exercise in which the students are given ~10 samples (including hand samples and thin sections) and asked to sketch and describe the cement types. The next one-hour lecture focuses on neomorphic processes and their products, including replacement, recrystallization, and polymorphic transition. As part of the lecture, we look at photomicrographs and hand samples that illstrate various neomorphic features, such as replacement dolomite and replacement chert. We establish criteria for distinguishing cements from neomorphic fabrics. This lecture is followed by a lab exercise that presents the students with ~10 rocks and thin sections and asks them to sketch and identify neomorphic fabrics. This lab is follwed by another one-hour lecture on compaction features, dissolution evidence, and determining paragentic sequences. If I am short on time, that is all I do for diagenesis. However, ideally, I continue with a lecture focused on the "dolomite problem" and some case studies of other types of diagenesis, as well as a third lab assignment that combines cementation, neomorphism, compaction, dissolution, and paragenetic sequences. As part of this section, I also try to incorporate examples of methods other than petrology (eg., fluid inclusion studies, stable isotope studies, dating) that are used for diagenetic studies. Later in the course, we take several field trips in which the students examine diagenetic features.

In this activity, students view a Quicktime video animation based on data from the North American Volcanic and Intrusive Rock Database (NAVDAT) to learn about the history of volcanism in the western U.S. during the last 65 million years. Students are guided through the complex data-rich animation with a series of instructions and study questions which highlight time-space-composition relationships and link to plate tectonics.
