This activity is divided into two parts - 1) Using data from primary literature to calculate mantle potential temperature beneath a ridge and an oceanic island ("hotspot"). 2) Using the transition zone thickness observed beneath a "hotspot" (Hawaii) to analyze contributions from anomalous temperature and composition. In addition to the student activity sheets, an Excel key, instructor notes, and student handouts are included below.

This activity uses Google Earth to explore the distribution of plate boundaries and hotspot volcanoes on Earth. It uses the ages and locations of the hotspot volcanoes to determine the direction and rate of plate motion.

This activity is an introduction to population sampling techniques. Students' will identify weaknesses and strengths of a variety of techniques and determine the best applications of the various methods identified.

This activity is intended to extend students' learning of fundamental physics concepts (e.g. reflection, refraction and transmission of energy) through a real-world application.

For nearly 100 years, the site that is now High Cliff State Park near Sherwood, WI was the site of a quicklime kiln. Local Silurian dolomite from the Niagara Escarpment was quarried and baked in large kilns before being shipped by boat on Lake Winnebago at the base of the escarpment. Rejected quicklime spoils are still present near the site of the kiln ruins, resting on the slope leading to the Lake Winnebago shoreline. This project is designed to use basic, low-cost field techniques to determine if any quicklime is moving downslope and into Lake Winnebago. Methods of analysis will include: 1) Placing survey stakes on the quicklime slope to see if they slope is moving, 2) Take several water samples from various points along the lakeshore to test the dissolved mineral content, and 3) Take several water samples from various points along the lakeshore to test the pH. Students will be asked to return to the site several times over the course of a semester in order take samples (particularly after precipitation events) and check the position of the stakes. Students will then use to data to project how far out into the lake the effects of the quicklime extend.

Key words: Quicklime, mass wasting, Niagara Escarpment, water pollution, dissolved minerals

In this activity the students calculate recurrence intervals for some historical crests on the Chippewa River and identify the 100-year flood plain in downtown Eau Claire. The students also evaluate the effect of a 20ft high stage event along the whole Chippewa River with the goal of showing how topography influences the size of the area affected by flooding events. The students also evaluate the effectiveness of a flood gate system located on campus.

Students are asked to determine the break even profit point for a service to be offered on campus, using an online break even calculator.

This activity is an inquiry lab where students observe the effects of temperature change on nitrogen dioxide gas, a common component of polluted air, to determine its color.

In this field lab activity, students will determine the density, pH and water content of prairie soil, transition soil, woods soil, and riverbed soil and compare their findings.

Gravels deposited as a result of continental glaciation are used to teach introductory-level earth-science students the application of the scientific method in a cooperative learning mode which utilizes hands-on, minds-on analyses. Processes that involve erosion, transportation, and deposition of pebble- and cobble-sized clasts are considered by students in formulating and testing hypotheses.

This activity is a two-part (three week) lab in which students initially develop a claim (non-scientific) and learn how to use evidence to support a claim. They then are provided with a scientific research question for which they need to make a claim supported with evidence from their own models (river/stream tables). Based on their results, they then ask a new research question, design the model, carry out their tests and report their results.

As a culminating assignment in Natural Hazards Planning, students work in teams to create 15-year mitigation strategy for a selected jurisdiction using the FEMA 386 methodology for prioritizing mitigation options.

The lesson content focuses on designing investigations concerning the notion of scale through a series of investigations on their campus. The overarching goal is to foster a connection to the earth through an investigation of the local environment.

Through this activity, students in a liberal arts mathematics class will develop experience with real-world statistical concepts through the context of sustainability: estimation, survey writing, sampling techniques, and data analysis.

Students spend the semester developing a stream restoration proposal for a local watershed. Students are asked to collect geomorphic field data and use these data to design a restoration plan.

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.

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).

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.
