This activity explores the cycling of carbon between the atmosphere (primarily as CO[subscript 2]) and biomass in plants, animals, and microscopic organisms. Students design soil respiration experiments using a protocol that resembles current practice in soil ecology. Three methods for measuring soil respiration are presented. Student-derived…

Given the present pace of educational globalization, educators--especially in rural schools--will benefit from an awareness of traditional knowledge as a significant contributor to sustainability. Many countries operate through a system whereby major decision making, especially in such areas as education and health, emanate from state levels of…

This quasi-experimental study compared the effects of concept mapping and teacher generated questioning on students' organization and retention of science knowledge when used along with interactive informational read-alouds. Fifty-eight third grade students completed an eight-day unit regarding "soil formation." Students who participated…

Geology is increasingly involved in the planning and implementation of community development projects throughout the globe. A partnership among the Water For Life organization, Wheaton College in Illinois, and the village of Tushile in Kosovo during the past few years has proven to be successful in potentially sustainable improvements, including…

In this paper, we apply a framework from Nikolas Rose to analyse the politics of "doing good" in food activist education, what we call food pedagogies. We argue that a detailed exploration of food pedagogies has been neglected in adult education and in the growing field of food studies, in spite of the rapidly proliferating forms and…

Soil science students are required to apply knowledge from a range of disciplines to unfamiliar scenarios to solve complex problems. To encourage deep learning (with student performance an indicator of learning), a formative assessment exercise was introduced to a second-year soil science subject. For the formative assessment exercise, students…

This article highlights examples from a middle-school science teacher's instruction using multimodal texts. Its importance lies in reconciling narrowed definitions of reading (and hence reading instruction) with the need to develop students' critical awareness as they engage with multiple sign systems, or semiotic resources, used for constructing…

Learning styles represent an integral component of the learning environment, which has been shown to differ across institutions and disciplines. To identify learner preferences within a discipline would aid in evaluating instructional resources geared toward active learning. The learning profiles of second-year soil science students (n = 62) were…

This article describes a series of activities in which students investigate soil, culminating in the biomimicry of reducing landfill waste. After students learned about soil's ecosystem structure and the function of its food web with nutrient cycling and decomposition, they discovered that they know a solution to reduce the trash in landfills by…

Integrating livestock into a cropping system by allowing ruminant animals to graze cover crops may yield economic and environmental benefits. The effects of grazing on soil physical properties, soil organic matter, nitrogen cycling and agricultural production are presented in this literature review. The review found that grazing cover crops…

This article describes a soil-testing activity that enables students to learn some interesting and useful things about how soil behaves under varied conditions. It offers a great way to give them a practical pre-engineering experience and will show them how engineers think about construction and how local soils influence building design. The…

Mass-volume relationships are a useful tool emphasized for problem solving in many geo-science and engineering applications. These relationships also have useful applications in soil science. Developing soils students' ability to utilize mass-volume relationships through schematic diagrams of soil phases (i.e., air, water, and solid) can help to…

Tropical rainforests are biologically rich ecosystems, which are threatened by a variety of different human activities. This study focuses on students' knowledge and understanding of rainforest locations, their reasons for protecting these environments and their familiarity with selected concepts about rainforest vegetation and soil. These…

Urban students often have limited access to field sites for ecological studies. Ubiquitous ants and their mounds can be used to study and test ecology-based questions. We describe how soil collected from ant mounds can be used to investigate how biotic factors (ants) can affect abiotic factors in the soil that can, in turn, influence plant growth.

Soil biogeochemistry, a discipline that explores the chemical speciation and transformations of elements in soils and the relationships between soils and global biogeochemical cycles, is becoming a popular course offering because it unites themes from a number of other courses. In this article, we present a set of case studies that have been used…
