A lesson plan for soil study utilizes the Tullgren extraction method to illustrate biological concepts. It includes background information, equipment, collection techniques, activities, and references for identification guides about soil fauna. (MCO)

Focuses on an experimental vegetable garden project in which grade eight students test their hypotheses on plant growth under variable soil conditions. Provides opportunities to integrate various scientific topics. (DDR)

Introduces a germination bag activity in which students investigate the questions: (1) Why is soil brown? and (2) How do roots know when a plant has enough water? Uses scientific journals and posters for student evaluation. (YDS)

Recent political and economic developments in Slovenia, especially its accession to the European Union in 2004, have led to a significant reappraisal of the geography curriculum in higher education, and particularly those elements dealing with the teaching of soils. Physical geography, and especially soils geography, has long been an important…

The implementation of problem-based learning (PBL) and other inquiry-driven educational techniques is often resisted by both faculty and students, who may not be comfortable with this learning/instructional style. We present here a hybrid approach, which combines elements of expository education with inquiry-driven laboratory exercises and…

This book is a result of a workshop where 14 science educators were invited to draft chapters on the implications that the research studies in a specific content area of science have for its teaching. The relations between social forces and perceptions of purpose and content lay behind discussions in the workshop, and influenced the emergence of…

Part of the Understanding Our Environment project that is designed to engage students in investigating specific environmental problems through concrete activities and direct experience, this unit introduces students to the idea of natural resources and focuses on resources found on land: minerals such as hematite and gypsum; rocks such as granite…

This document reports on a project designed to identify and validate the essential competencies needed by agriculture students in order to enter and advance successfully in agricultural occupations in Wyoming. Competency lists and validation studies were collected from other states. A group of vocational agriculture teachers developed a list of…

This document is a collection of 43 overhead transparency masters to be used as teaching aids in a course of study involving soils such as geology, agronomy, hydrology, earth science, or land use study. Some transparencies are in color. Selected titles of transparencies may give the reader a better understanding of the graphic content. Titles are:…

The guide provides information on professional opportunities in natural resource management, planning, and research. Reasons for careers in forest service are presented and a brief description of the forest service is provided. Career opportunities in the following areas are described: forestry, engineering, geology, hydrology, landscape…

Eight professional geography research papers presented at the Geography Section of the Ohio Academy of Science annual 1975 meeting are provided. The papers examine various aspects of the environment, energy distribution, cultural and geographic change, and ethnic distribution. The titles of the eight papers are (1) Racial and Ethnic Redistribution…

The general purpose of this study was to develop an educational program for agricultural development in Iraq, and to identify the best method for its implementation. The proposed program was based primarily upon relevant factors identified through data collection from the following sources: official records, current literature, and the writer's…

Discusses the use of a computer program designed to solve the mathematical model associated with soil nutrient uptake by plant roots and to predict the nutrient uptake. Describes a user-friendly personal computer version of this program. (TW)

Describes an earth science unit in which students study soil from their own backyards through a series of integrated activities. Introduces several earth science concepts, including local geology and the development of different types of geological regions. Presents activities to make a county soil map, measure moisture in soil, and measure the…

Describes activities which demonstrate the abundance of organisms living underground. Provides outlined directions, lists of materials, and a soil ecosystem transparency for delving into the properties of soil. (RT)
