In this unit, students work in small groups to collect and record data about soils using various soil testing and classification methods at a series of stations. The methods they use are relevant to the societal issue of their choice that involves soil. Through this process of testing, data collection, and interpretation, they develop the baseline soil content knowledge and skills necessary to create their own Soils, Systems, and Society Kit.

The application of Global Navigation Satellite Systems (GNSS) in the earth sciences has become commonplace. GNSS data can produce high-accuracy, high-resolution measurements in common reference frames. Static GNSS methods take advantage of long occupation times to resolve fine measurement and time-series data to capture events such as tectonic deformation, earthquakes, groundwater depletion, and slow-moving landforms. This unit focuses on design and field execution of simple static surveys, emphasizing the benefits and limitations of the technique. Students will learn which applications the technique is most applicable for as well as the standard data-processing techniques. Additionally, students advance their understanding of GNSS systems through interpretation of field data from static surveys and public data sets of continuous-operation stations. This unit prepares students to design and implement a survey of their own through hands-on instruction and demonstration of rapid-static or static techniques in a field setting.

Note: Although the term GPS (Global Positioning System) is more commonly used in everyday language, it officially refers only to the USA's constellation of satellites. GNSS (Global Navigation Satellite System) is a universal term that refers to all satellite navigation systems including those from the USA (GPS), Russia (GLONASS), European Union (Galileo), China (BeiDou), and others. In this module, we use the term GNSS to refer generically to the use of one or more satellite constellations to determine position.

Using a systems dynamics approach, students will work in groups to conceptualize and construct a model of the global carbon cycle considering five major Earth systems: atmosphere, hydrosphere, geosphere, cryosphere, and biosphere. The models will draw on information from the pre-class activity and invoke system features such as boundaries, stocks, flows, and control variables. Using a scenario describing a global, catastrophic event, the students will consider how new conditions change the behavior of carbon cycling in their model world. Students will use the model to explain changes in environmental variables such as permafrost cover, atmospheric gases, and global temperature, as well as feedbacks within the system.

How do slope characteristics and magnitude of forces dictate whether or not a slope will fail? Can environmental and built characteristics change the magnitude of these forces? In this unit, students qualitatively and quantitatively consider the impact of slope angle, driving force, and frictional force on mass-wasting potential. A map activity prompts students to think about how climatic, tectonic, and geologic factors, as well as population and land use characteristics can influence mass-wasting potential.

Online-adaptable: Part 1 (lecture) and Part 3 (discussion) are particularly straight forward to adapt to online. Part 2 student exercise is typically done with printed maps but can be successfully adapted to online by having synchronous groups of students work together to annotate digital map files using: 1) PDF annotation tools in Adobe or 2) putting the map images into a Google Slides file and using the scribble tool. Google Earth files are also provided as an additional option.

Unit 3 addresses concepts related to urban-atmosphere interactions. The content explores how urban landscapes and atmospheric constituents modify or interact with the atmosphere to affect temperature, clouds, rainfall, and other parts of the water cycle. Fundamental concepts of weather and climate are established. The unit then transitions to focus on the "urbanized" environment and its complex interactions with the atmosphere. Students will learn about interactions such as 1) urban modification of surface temperature and energy exchanges; 2) water cycle components; 3) cloud-rainfall evolution within urban environments; and 4) applications to real societal challenges like urban flooding. The unit integrates basic meteorological/climatological analyses, geospatial thinking, and integration of scientific concepts within a real world context.

Online-adaptable:Main exercise is a jigsaw activity that can be successfully done in an online course; but it does take a bit of extra effort to arrange the students into two different sets of online groups with online collaboration. This will probably be more success in a synchronous format.
OR the unit could be adapted away from the jigsaw format with Parts 2 and 3 below combined into a single exercise done individually or in static small groups.

In this unit, students investigate water resources of their own area or another area of personal interest, which typically gets them very excited. They apply their knowledge from Units 1 and 2 to identify the water reservoirs which are most important to their local community, the transport pathways responsible for delivering water to those reservoirs, and the relevant and available techniques for monitoring those resources. They also consider interests by different stakeholder groups in relation to water resources and how these potentially competing interests could influence water policy, infrastructure, and distribution in a community.

Online-adaptable: The Unit 3.1 exercise is really designed as an in-person stakeholder analysis that might be more challenging to translate to online. However the larger part of the unit, Unit 3.2 Local Watershed investigation, is designed as a student project that can be done individually and would translate well to online.

An eruption at Yellowstone could have devastating effects on large areas of the US and Canada, but what is the likelihood of such an eruption occurring? This unit has students explore seismic data for the last several decades and calculate mean recurrence intervals of seismic swarm events. Additional geodetic data (GPS, InSAR) are used to investigate whether or not seismic swarm events reflect volcanic activity. Finally, students will explain the source and causes of earthquake swarms in the context of responding to non-scientists' concerns that swarms indicate an impending eruption.

The purpose of this unit is to explore, compare, contrast, and calculate energy fluxes from different CZO field sites to better appreciate the critical differences in the driving radiative forces affecting each site. This module will help students complete their semester-long project by introducing them to critical baseline data collection and databases related to energy budgets.
The primary data set for this activity is the CZO tower network of a dozen met/flux towers spanning six different biomes/sites. Each site has a slightly different data format but it is easily manipulated in a spreadsheet. The lesson is divided into the following engaging activities:

Background lecture: Introduction to water and energy fluxes and balances
Database access and graphing activity: Students will learn what data exists in the CZO database and how to load and manipulate it using Excel.
Discovery activity: Students in small groups will compare monthly bar graphs of energy fluxes drawn from six Ameriflux sites and address questions concerning linkages with other variables and processes affecting energy partitioning.
Reference ET Activity: Students will learn about the Penman-Monteith formulation of evaporation and calculate this from common meteorological data and compare with field measurements of evapotranspiration. The class will discuss these results as time allows.

The purpose of this unit is to explore, compare, contrast, and interpret carbon fluxes from the Ameriflux network to better appreciate the critical factors that account for the different timing and magnitudes of fluxes among these sites. This module will help students complete their semester-long project by introducing them to critical baseline data collection and databases related to carbon budgets.
The primary data set for this activity is the Amerflux network database, which spans over 150 sites throughout the Americas. Each data set is uniformly formatted and can contain up to 45 fields of meteorological and flux data collected from various eddy correlation tower instruments. The lesson is divided up between the following engaging activities:

Background lecture: Introduction to carbon fluxes and balances
Discovery Activity: Students in small groups will compare various annual flux records from four different sites to address questions regarding driving variables, correlation among variables, and causative factors responsible for the overall trend in annual CO2 flux. Group results will be shared and discussed by the whole class as time allows.
Database Access Activity: Students will learn what data exists in the Ameriflux data base and how to load it into an Excel spreadsheet for display using an Amerflux site that also is part of the CZO network.
Carbon Flux Hypothesis Activity: Students will develop a simple hypothesis regarding the timing and/or magnitude of CO2 fluxes and use data from the Ameriflux database to support their ideas.

How can community stakeholders use the landslide susceptibility model to inform planning and infrastructure decisions? Students will create a landslide risk analysis report and assessment plan for a specific region, considering a suite of environmental, social, and political factors. This unit is a culmination of student experiences from prior units within this module, and requires interdisciplinary considerations and holistic approaches in the design process of this report. Specifically, this unit will require reflection on landslide detection protocols (Unit 1), factor categories that correlate to the distributive pattern of landslides in a region (Unit 2), and the development of a susceptibility map (Unit 3) in conjunction with considerations of Earth processes, infrastructure, and sociopolitical factors (policy, budgets, cultural preservation) associated with hazard mitigation. This unit uses ArcMap software.
This unit, along with some exam questions, serves as the Summative Assessment for the module.

Landslides can have profound societal consequences, such as did the slide that occurred near Oso, Washington in 2014. Forty-three people were killed and entire rural neighborhood was destroyed. In this unit, students consider the larger-scale tectonic and climatic setting for the landslide and subsequently use lidar and SRTM (Shuttle Radar Topography Mission) hillshade images, topographic maps, and InSAR (interferometric synthetic aperture radar) to determine relationships between landscape characteristics and different types of mass-wasting events. They conclude by considering the societal costs of such a disaster and ways that communities in similar situations may mitigate their risk.

Online-adaptable: The exercises in unit are completely digital and thus at a logistical level it can be switched to online fairly easily. However, due to the relative complexity of the data investigations and group discussions, there will still be a fair bit of instructor support needed and/or extended small group that should be arranged.

How much and how quickly does Earth's surface respond to changes in a glacier's mass? How can geodesy help scientists understand the relationship between ice mass change and changes in the bedrock surface? How are these processes related to regional sea level changes? In this unit, students use visualizations, bedrock GPS (Global Positioning System), and ice elevation data from Greenland's Helheim Glacier to investigate the concept of post-glacial rebound and the relative contributions of rebound and ice melting to regional sea level changes in Greenland.

Online-adaptable: The lecture and main data analysis exercise can easily be moved online. The final piece is a discussion or [linkhttps://serc.carleton.edu/introgeo/gallerywalk/index.html 'gallery walk'] which can also be successfully done online but may take a little more preparation. For instance, in the case of the gallery walk, the images and questions can be available for online viewing with space available for student comments. Online groups then rotate through the stations virtually.

In this two-day activity spanning Units 4 and 5, students analyze spatial variation in climate through a map-based jigsaw exploration of NASA's Earth's Radiation Budget Experiment (ERBE) data. By the end of the activity, students will have created maps and graphs illustrating the global radiation balance and used their knowledge to develop and refine hypotheses regarding impacts of global climate change.

Unit 4 (day 1 of activity) begins with a brief student exploration of the global impacts of climate change and how maps can be used to effectively communicate these patterns. Students are then broken into small groups to analyze a map of one of three ERBE datasets. Students are asked to interpret geographic patterns in these data, infer the underlying causes of patterns they observe using knowledge they have accumulated in the previous units, and create an annotated map that clearly illustrates their observations and inferences. During the following class period (Unit 5), they will share their findings with a new group of classmates and work to synthesize the data to estimate the radiation balance.

In this unit, student groups will evaluate different environmental case studies to critically investigate qualitative and quantitative data analysis, collection, and inquiry. Students will begin to consider different forms of sensory-related data collection and how experiential knowledge informs the ways in which one forms analytical, evaluative questions. Student expert groups are provided one case study (different expert groups will examine at least two different cases) that has a number of different kinds of resources that students will examine (e.g. journalistic, scientific, narrative, visual, auditory). Students will use cooperative learning methods to engage with problem-based inquiry rather than have the case study information delivered via instructor-based lecture. Given that students across disciplinary contexts may not have been exposed to scientific methods of investigation, this unit encourages systems thinking alongside other methods of investigation. As students consider the variety of perceptions that occur within a group of people sharing an environmental experience, students are able to consider the impact that different types of data have on one's perception of data collection and its analysis. This exercise also demonstrates the utility of interdisciplinary thinking -- by examining data sets from multiple academic disciplines, students gain a more complete understanding of the case study compared to what they would have understood by examining data from a single research approach. The activity also provides students with an opportunity to practice interdisciplinary thinking and collaboration skills. The cases address several key environmental challenges: soil contamination, water resources, and the impacts of industrial agriculture.
A collaborative learning method is used in conjunction with guided class and group discussion to critically examine different types of data and encourage consistency of data analysis between student groups. This unit uses a group exploration and presentation activity to ensure equal distribution of materials and accountability among class participants. In essence, the students teach each other about the case studies with the instructor providing questions to elicit depth and synthesis between groups as well as to ensure that critical data analysis is undertaken.

Units 4, 5, and 6 provide the opportunity for students to delve into a greater examination of food security at a regional level in small teams selecting one of the following locations (Caribbean, New York City, or Nebraska) OR a new location of their choice (provided that information and datasets are easily available and students will work with the instructor prior to the start of the unit) to apply skills and concepts taught in Units 1-3. Unit 4 materials are designed to provide a place-based overview for students to prepare them for the summative assessment, to be submitted in Unit 6, a community-based action plan of how the selected community can increase food security and lessen vulnerability.

Students assess the risks from three different volcanoes based on the Risk Equation, Risk = Hazard x Value x Vulnerability. The three volcanoes--Fuego Guatemala, Rinjani Indonesia, and Moana Loa Hawaii--have varying characteristics, thus giving the opportunity for dynamic conversations and insights into different volcanoes and their affected communities. The final group product is a table that helps students to identify the volcano that poses the greatest risk and thus most needs monitoring. Students must present a clear rationale for why it is selected over other volcanoes, taking into consideration the volcanic hazards, population characteristics, and infrastructural vulnerabilities for each volcano. Students also complete a preparatory exercise on the characteristics of different Volcanic Explosivity Index (VEI) eruptions.
