Is groundwater mining sustainable? In Unit 4 students compare and contrast long-term (decades) groundwater well levels in six states representing the East Coast, West Coast, and Midwest Plains states. Satellite imagery maps of the well locations will give students an idea of the land cover, specifically the presence of irrigated crops. Using groundwater well data from the USGS, students will recognize the depletion of aquifers in the western United States (e.g., the Ogallala/High Plains Aquifer), or groundwater mining, as an unsustainable practice.

In this unit, students construct and present a standards-based, K -- 8 Soils, Systems, and Society Kit that consists of lessons and supporting materials around a locally and broadly relevant societal issue that involves soils. After learning about the Kit assignment and choosing their societal issue, students have at least two weeks outside of classwork time to develop a kit that integrates soils content with interdisciplinary systems taught through scientific practices. After completing their Kits, students present them to the class for review and final summative assessments.

Students will use SoilWeb -- , a smartphone and web application that pulls detailed soil survey data from both the 1:24,0000 Soil Survey Geographic database (SSURGO) and the 1:250,000 scale State Soil Geographic database (STATSGO). Students will retrieve soil information for the soil beneath them. They will diagram soil horizons and compare them to a profile of soil organic matter and determine the most fertile horizon. Finally, students will complete a jigsaw activity comparing local soil erosion rates, soil horizons, and soil organic matter to other sites. After students share site comparisons, they will reflect on our agricultural future and solutions needed to mitigate lost soil resources. They will discuss how the speed at which we implement soil solutions will impact society and the economy.

This is the second module of a two week-long unit on hydrology in an upper-level undergraduate course on the Critical Zone. After Unit 5.1, students should have a basic understanding of the fluxes and reservoirs in the context of a tree and basin water balance. In Unit 5.2, students will learn how to apply environmental sensor data to larger catchment or regional scales (Part 1) and will connect hydrologic processes in the Critical Zone to societal needs through a quantitative resource availability and decision-making exercise (Part 2).

Units 3 and 4 of this module explored how water resources are used for agriculture in the United States and how this can vary depending on location. In Unit 5, students explore how agricultural practices can affect the water quality in streams, rivers, lakes, and coastal areas. Important concepts in this unit include processes that transport suspended material (e.g., sediment) and dissolved material (e.g., nutrients) away from crop fields and into regional water bodies. The effects of dissolved nutrients on the health of the water ecosystems will be presented with examples of hypoxic zones in coastal areas and lake eutrophication. This last unit is well-suited to foster student advancement in systems thinking.

Students will investigate how the factors that influence erosion work together to produce an overall erosion rate. In agricultural areas, these factors are rainfall-runoff erosivity, soil erodibility, slope characteristics, and agricultural practices. Students will analyze changes in precipitation predicted by climate change models to consider how a changing climate could influence erosion rates in agricultural areas.

In this week-long unit students will explore Critical Zone function and dynamics as they relate to nutrient cycling in agricultural systems and nutrient pollution into aquatic systems. This unit is generally subdivided into three sections: (1) nutrient pollution (2) agricultural importance and (3) Critical Zone function and dynamics in relation to nutrient cycling. The students will use data sets, interactive activities, primary literature, and videos to allow them to examine the role that the CZ plays and how that role changes with differing land uses. Important present-day topics of food production, clean water, nutrient pollution, and sustainable agriculture are examined using a CZ lens. Students will interact with each other on a variety of scales (individual, small groups, entire class) and using a variety of modes (presentations, written reports, question and answers, and class discussion) in this unit. Additionally, optional activities are provided if lab activities are able to be accommodated. The unit ends with a summative assessment assignment that is based on an innovative call for proposals to combat one of America's most widespread, costly, and challenging environmental problems: nutrient pollution.

For a given region, students will use what they have learned about the interdisciplinary problem of soil sustainability to make recommendations for agricultural practices in response to potential changes in climate. Students will present their findings in a fact sheet that describes best practices for mitigating potential changes while remaining sensitive to stakeholder concerns and feasibility. Finally, students will complete a final personal reflection on their own learning.

In this unit, students address the issue of groundwater demands and environmental justice in the arid Southwest, a region with some of the largest percentages of Hispanics and Latinos in the United States. Students discuss the Rule of Capture, the overuse of water resources, and the dwindling supply of groundwater in many parts of the Ogallala Aquifer. Students connect groundwater's role to the hydrological cycle and consider how issues of inequity can occur when groundwater is not properly regulated.

Humans not only reside in the Critical Zone, they depend upon the land and water to provide sustenance. This unit will examine how humans affect soil resources and ecosystem services in the Critical Zone through food production. In addition, it will discuss farming practices that led to the Dust Bowl in the 1930s. Finally, it will examine emerging efforts to grow food locally such as Community Supported Agriculture (CSAs) and urban gardening programs.

To prepare for this reflection, students are assigned to do background reading on the organization they will/wish to work with for the Service Learning component of the course. Students then are guided into a reflection with the following questions:

Why should you know about the people or organization with whom you'll be working?
Why do you think this partner was chosen?
After reading about the partner organization, how would you like to contribute to their work, (what kind of support would you give and/or project would you do?) How does it your idea/project relate to the content of the course and the organization mission and goals?
What are you hoping to learn from the collaboration/ project?
What do you hope to have gained from this project and
What do you think your service-learning partner hopes to have gained after completion of this project?

The assignment also gives students practice in eliciting their own thoughts and reflections when approaching a new experience

This five-day lesson introduces students to micrometers, explains how to read and use these tools, and assesses students' abilities to demonstrate proper micrometer usage and reading.

In this resource, students learn about freshwater resources, how NASA uses satellites to measure precipitation, and how that data can be used in agricultural practices. Students use data from the NASA Global Precipitation Measurement satellite to explore precipitation patterns in two parts of the world and then make recommendations for how to reduce water use in agriculture and in their own lives.

This lesson is designed to familiarize new students with a bench grinder.  Students will learn the key PPE, parts, and then demonstrate how to use it.
