In the first part of this lab, students learn about land ice and the processes and timescales involved in glaciation. In Part B, they use an online interactive to explore how glaciers provide scientists with evidence for climate change. Finally, students use image processing software to measure how much area a real glacier has lost over time due to rising temperatures.

When populations live in areas where natural resources are scarce, conserving them becomes critical for survival. The case study presented in this lesson introduces students to a real drought that has been developing in the Colorado River basin for many years. The Colorado River is the major source of water for people in the driest part of the United States. More than 30 million people in 7 states depend on this river as the primary source of their water. In this lesson, students discover how changes in climate over the Colorado watershed are reducing the amount of fresh water available in the river. They also see how the population of the region that uses this water has grown, resulting in increasing demands on a dwindling resource.

This lab introduces students and other interested users to the Neotoma Paleoecology Database and Neotoma Explorer. Neotoma DB is a public-access and community-supported repository of paleoecological data, mostly from the late Quaternary. These data are widely used by scientists to study species responses to past climate change.

In this physical geography lab, students examine the relationship between solar altitude, solar declination, and temperature regimes. Using data collected in the field, mathematical relationships, and temperature records available on the Internet, students compare the insolation and climate in their location to that of other locations.

This activity utilizes a sandbox analog model which is used to create normal faults and a foreland propagating fold and thrust belt. For the normal fault portion of the activity, students investigate the progression of normal fault generation and accumulation of offset. During the thrust fault portion of the activity, students evaluate (1) the initiation angles of thrust faults, (2) compare that to the final angles to understand how fault angles rotate with progressive thrust propagation, and (3) they visualize how the critical slope angle is involved in the initiation of younger thrust faults. In addition, they conceptualize methods utilized to evaluate the magnitude of fault offset, and vertical and horizontal shortening. This activity is motivated by and utilizes a sandbox model from: Dell Castello, M., and Cooke, M., 2008, Watch faults grow before your very eyes in a deformational sandbox: Journal of Geoscience Education, v. 56, p. 324-333. Tips for the activity: I place a sheet of sandpaper under the sand on one side of the compression experiment to test the outcomes with varying basal friction. For the extension portion, I attach separate metal sheets to the stationary wall and the moving wall, under the sand. These sheets are joined by elastic fabric. To save money, mix non-toxic paint powder into basic sand to get colored sand.

A short laboratory exercise, conducted by students, is used to illustrate the multiple factors that contribute to rocks' varied responses to deformation. Analogue materials (play-doh, notebook springs, butter, silly putty, plastic bags, etc.) are used to illustrate many of the controlling factors such as lithology, stress, temperature, confining pressure, strain rate, preexisting weaknesses, and accumulated strain. The analogue experiments are presented in conjunction with parallel data from deformation experiments and field studies. The tandem presentation of analogue experiment and real data requires the students to obtain a natural "feel" for rheologic parameters and more exhaustively analyze the important conclusions obtained from field and deformation experiment data.

Stratified lakes exhibit vertical gradients in organisms, nutrients, and oxygen, which have important implications for ecosystem structure and functioning. Mixing disrupts these gradients by redistributing these materials throughout the water column. Consequently, it is critical to understand the drivers of lake mixing and thermal stratification, especially because of the sensitivity of lake thermal conditions to altered climate. In this module, students will explore spatial and temporal patterns of lake mixing using high-frequency temperature data from lakes around the world. They will also explore how increases in air temperature affect thermal stratification by interpreting output from a lake model. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

Library Carpentry lesson: An introduction to Git. What We Will Try to Do Begin to understand and use Git/GitHub. You will not be an expert by the end of the class. You will probably not even feel very comfortable using Git. This is okay. We want to make a start but, as with any skill, using Git takes practice. Be Excellent to Each Other If you spot someone in the class who is struggling with something and you think you know how to help, please give them a hand. Try not to do the task for them: instead explain the steps they need to take and what these steps will achieve. Be Patient With The Instructor and Yourself This is a big group, with different levels of knowledge, different computer systems. This isn’t your instructor’s full-time job (though if someone wants to pay them to play with computers all day they’d probably accept). They will do their best to make this session useful. This is your session. If you feel we are going too fast, then please put up a pink sticky. We can decide as a group what to cover.
