Following evolutionary theory and an agriculture model, ecosystem research has stressed bottom-up dynamics, implying that top wild predators are epiphenomenal effects of more basic causes. As such, they are assumed expendable. A more modern co-evolutionary and wilderness approach--trophic cascades--instead suggests that top predators, whose…

The Harvard Forest Schoolyard Ecology Program provides teachers and students with the opportunity and materials to participate in regionally focused ecological studies under the guidance of a mentor scientist working on a similar study. The Harvard Forest is part of a national network of ecological research sites known as the Long Term Ecological…

Describes teaching ecology by using highway travel. Provides an outline for the travel observation checklist. Discusses some practical information for using the activity. (YP)

Over 600 students taking advanced level biology in more than 130 schools were surveyed to investigate the relationship between their attitudes toward fieldwork and factors associated with fieldwork teaching. Responses given by the students and their teachers are presented and discussed. (Author/JN)

Presented is an activity designed to teach the use of the scientific method to non-science majors. Collecting, classification, and follow-up activities for a beach trip are discussed. Two simple dichotomous keys are included. (CW)

This article details the rationale and purposes of an ecology-travel course-trip made available to preservice education majors at a small liberal arts city college between 1975 and 1987. Included are the course objectives, pretrip planning and procedures, posttrip debriefing, and statistics on destination, participation, duration, and expenses for…

Presents information on the population density, breeding biology, habitats, and food of the magpie bird ("Pica pica"). Suggests and outlines several student projects that have been beneficial in teaching animal behavior and ecology. These investigations focus on diet, territory size, and food hoarding. (DH)

Biodiversity is the extraordinary variety of life in this planet. In order to be fully appreciated, biodiversity needs to be experienced firsthand, or "experientially." Thus, the standard classroom lecture format is not the ideal situation for teaching biodiversity and evolutionary concepts, in that student interest and understanding are…

Background information, procedures, and suggestions for bird feeder studies easily conducted in high school or middle school settings are provided. Data collection and analysis are discussed. Examples of charts produced by these activities are given. (CW)

Many teachers have found that, no matter how enjoyable ecological studies are, students tend to dislike the computation of the large amounts of data gathered. Included is a description of an experiment that utilized time-saving features as well as the instructional and motivational benefits of using a computer spreadsheet program to analyze and…

Two designs of undergraduate terrestrial ecology and behavior field courses are described and compared. These include using a variety of projects and using a single individual research project. The relative educational benefits of each are considered and the advantages of each type of course are discussed. (Author/CW)

Described is a field trip for high school and college students to the country of Belize to study tropical ecology. Discussed are planning and special considerations. Included are a sample schedule and a planning guide. (CW)

Lichenometry is described for use in the study of biology and physical weathering. Discussed are lichens in general and an outline for studying growth and ecology. A problem solving format is used. (CW)

This pre-school through grade 12 environmental education learning continuum was designed to help educators with a systematic method which develops an environmental ethic among students. It consists of: (1) preschool through third-grade activities (which stress environmental awareness and sensitivity); (2) intermediate level activities (which give…

This lesson plan demonstrates how to use common animals in your backyard or school grounds to study basic ecological principles with students. An example study uses squirrels for observational study. Includes background information, references, suggested equipment, activities, and observation techniques. (MCO)
