A Growing Concern: Sustaining Soil Resources through Local Decision Making

Strengths of the Module

Undergraduates explore soil erosion challenges in the context of agricultural land management and climate change. Soil erosion and solutions are explored through an active learning environment (e.g. physical modeling, think-pair-share, and jigsaw exercises), encouraging critical thinking and reflection. The entire process requires that students develop interdisciplinary thinking skills to synthesize how soil erosion relates to land management decision-making.

Students investigate the basic interactions between Earth's spheres, a key component of which is the positive feedback between agricultural practices and the sustainability of soil as a vital resource. They apply systems thinking as they consider how predicted changes in climate will impact soil sustainability in their local area.

Students challenge their conceptual models about soil erosion and sustainability through the use of real-world geoscientific data, both data they generate and data gathered from existing USGS and USDA databases. In the process, they develop data collection and analysis skills and the ability to access existing data using technology tools.

Students gain an understanding of the nature and methods of geoscience through building observational skills, using charts to characterize soil samples, and working with geospatial data to understand how humans alter geologic rates of change. Geoscientific habits of mind will grow through working with authentic data and translating scaffolded knowledge into decision-making as students take on the role of agricultural "experts."

The users of this soils and agriculture module completed this module within most courses within a two-week period. It is designed to build content while engaging students in a few practices and crosscutting concepts. There are no particular performance expectations completely addressed within this unit, although the content will assist students in building proficiency towards performance expectations around human impacts on our Earth system.

This module is appropriate for introductory-level undergraduate science courses such as environmental science, geology, agriculture, and soil science. It could also be used to introduce the scientific concepts relevant to social science (i.e. policy-making, economics). The module is designed to stand alone and can be adapted to any class size and format (large- or small-enrollment classes and interdisciplinary courses). This six-unit module utilizes active learning strategies by incorporating pre-work, in-class activities, and follow-up homework. Units 1 through 5 are designed to stand alone. If completed sequentially, they culminate in a summative fact sheet that builds from all units (Unit 6). The module could be adapted to upper-level courses in those fields.
