The Great Lakes are one of the world's greatest reservoirs of fresh water, the foundation of Ontario's economic development, a primary force in ecological systems, and a base for pleasure and recreation. They are also a magnificent resource for the teachers of Ontario. Study of the Great Lakes can bring to life the factors that shape the ecology…

The Great Lakes are one of the world's greatest reserviors of fresh water, the foundation of Ontario's economic development, a primary force in ecological systems, and a base for pleasure and recreation. These lakes and their relationship with people of Canada and the United States can be useful as a subject for teaching the impact of human…

This document consists of three sections. Section I contains 19 activities developed by master teachers for the Science World '84 summer science program. These activities focus on studies involving airplane controls, trash bag kites, computers, meteorology, compass orienteering, soils, aquatic ecosystems, bogs, and others. Objectives, materials…

Polk County's environmental education program was integrated into the existing curriculum, K-12, by employing an interdisciplinary approach coordinating the various disciplines. Emphasis is placed on the following phases of environmental education at the designated grade levels: (1) primary - awareness, (2) intermediate - concern and information,…

The purpose of this project was the establishment of materials suitable for slow learners in a life science program. The research focused on the development and testing of an eight-week study in life science and evolved through three phases: preparation, writing, and assembly of a student text and a teacher's handbook; preliminary testing during a…

This life science guide is one of a series of guides, K-12, that were developed by teachers to help introduce environmental education into the total curriculum. The materials contained in the guide are supplementary, and designed to aid the science teacher in providing the kinds of experiences needed by students to gain an understanding of the…

A field trip to a science activity center in Southwest England for secondary school students is described. (BB)

Describes a basic biotechnology investigation that includes restriction and ligation of plasmid DNA, transformation of bacteria and cloning of these bacterial cells. Discusses laboratory procedures and another activity in the identification of unknown plasmids by studying agarose gel electrophoresis photographs. (CW)

Introduces a construction method for a bubble made of polyurethane plastic and its applications in an ecology classroom. Provides the materials list, directions for bubble construction, and classroom activities. (YP)

Outlines the genetic elements found in the bacterial cell which play a role in recombining DNA sequences. Provides a core structure to which the mechanisms occurring in and between bacterial cells can be related. Discusses the practicalities of recombinant DNA techniques. (Author/CW)

Contains three articles designed to help practitioners with practical assessment for the GCSE. Articles include: "GCSE Biology Practical Assessment--Can the End Justify the Means?"; "Investigating the Effect of Catalase: GCSE Assessment Practical"; and "An Experimental Design for GCSE Physics." (CW)

Deals with a fungus that plays an important role in the forests of Asia as a decomposer of recently dead trees and in agriculture as an important edible mushroom. Describes how to culture these mushrooms including materials, conditions, and troubleshooting. Gives ideas for classroom activities. (CW)

Described is a science experiment involving the isolation and study of microorganisms. Bacteria from the mouth are cultured on blood agar culture plates and are then exposed to four different mouthwashes to test their effectiveness. (DS)

The Australian Web of Life biology course is evaluated as to its philosophy and mode of instruction. The study reveals that the use of inquiry-oriented practices is relatively low and that teachers consider the objectives of the course more important than do their classes. (Author/DS)

Summarizes what is known about the effects of marijuana use on health. The topics included are its chemistry and the metabolism; the effects of acute intoxication on learning, memory, intellectual performance, driving, and other skilled performances; and effects on lungs, brain, heart, and other systems.
