Describes how to construct a model of a DNA molecule with inexpensive materials. (BR)

Presents a method which organizes concepts and relates different phenomena to a single model of ecology. Describes how this model is used to explain the overall significance of biological and ecological cycles and its usefulness in helping students to understand the various dangers to and remedies available for an ecosystem. (CS)

Presented is a hand model which can be used to compare and contrast mitosis and meiosis. Features and procedures of the technique are detailed. Limitations of the models are discussed. (CW)

Describes the use of constructivism in teaching human anatomy. Provides directions for constructing arm-hand and leg-foot models that include extensor and flexor muscles and that are easily and cheaply constructed. Lists resources that provide ideas for using such models depending upon the curriculum implemented in a school or the course that is…

To examine the dynamism and productive qualities of multicultural interaction, a chromosomal bivalency model was borrowed from the biological sciences. Dilemmas inherent in contact between cultures emerge from the sites of multicultural conflict. Understanding these dilemmas allows interactants to have insights into other cultures as well as into…

Describes construction of a model that can demonstrate the activities of the human lungs. Among these are the effects of occluding the trachea and respiratory opening, the action of diaphragmatic and negative-pressure breathing and pressure changes. (SA)

An approach is suggested for teaching science history through inquiry training. A series of investigations are given for illustrating to students the manner in which organisms are grouped taxonomically. (SA)

This document provides technical information and simple instructions for constructing 84 different pieces of science equipment. Each entry includes: (1) name of item; (2) purpose of the equipment; (3) person who submitted the information; (4) line drawing of prototype; (5) list of low-cost materials needed; (6) construction procedures; (7)…

Directions for the construction of a model bog habitat are provided including examples of plants and animals which may be suitable. Activities that use this model are suggested. Background information on the ecology and chemistry of the bog is included. (CW)

Describes a computer model characterizing the balance of soil-plant Nitrogen that allows students to see the likely consequences of different biological and weather-related parameters. Proposes three uses for the model: (1) orienting beginning students to understand the soil Nitrogen cycle; (2) providing information for advanced students; and (3)…

Instructions are given for constructing two models, one to illustrate the general principles of symmetry in T=1, T=3, and T=4 viruses, and the other to illustrate the disposition of protein subunits in the T=3 plant viruses and the picornaviruses. (Author/CW)

Presents an activity in which models help students visualize both the DNA process and transcription. After constructing DNA, RNA messenger, and RNA transfer molecules; students model cells, protein synthesis, codons, and RNA movement. (MDH)

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

Presents a model, organizational procedures and evaluative findings of a science curriculum development program. Inservice teachers co-operatively developed modular science courses for underachievers, lists of science skills and attitudes, and materials for environmental science, physical science and biological science courses. (ML)

The Nordic Conference of 1985 was convened for the purpose of fostering cooperation between science and technology educators within different fields and at different levels, with approximately 40 science and technology educators from Finland, Norway, Sweden, Denmark, India, the United States, and Yugoslavia participating. This report contains 27…
