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

Described is an exercise which uses inexpensive and easy-to-make materials to demonstrate the basic fundamentals of heredity. Discusses two approaches using a hypothetical insert to demonstrate inheritance, mitosis, meiosis, and genotypic and phenotypic frequencies. (CW)

Describes a game that illustrates the principles of population genetics and helps explain the occurrence of evolution through changes in gene frequencies. Demonstrates the importance of genetic variability in evolution: winning is achieved by a player's species becoming "completely heterozygous" for six characteristics. Players move directed by…

Described is The McKusick Catalog of human genetics. This article discusses how biology instructors could make use of this reference and answers specific questions regarding its use. (CW)

Describes materials and techniques suitable for class fieldwork on the ecology of the cyanogenesis polymorphism of white clover. Details of a school trial are presented and discussed. (Author/EB)

Presented is a detailed look at some published materials showing the widespread nature of the misuse of genetics terminology. Suggests that similar problems can be found in any genetics text. Concludes with a plan for urgent action and suggestions for improvement. (Author/CW)

Considers six key concepts in human genetics in a question-and-answer format designed to help guide students to an understanding of the concept. Lists eight workshops in human genetics for high school biology teachers and four curriculum material packages on human genetics. (CW)

The field of biotechnology, and specifically recombinant DNA technology, is transforming the way that many feel about the nature and purposes of biology. This newsletter annual supplement contains several articles addressing the topic of biotechnology and the importance that the topic should be given in science classes. James D. Watson's article,…

The teacher's edition for the Intermediate Science Curriculum Study Level III unit entitled "Why You're You" provides specific suggestions for teaching the seven chapters included in the unit. The unit deals primarily with the concepts of genetics and a brief discussion is included in the beginning about some of the basic ideas in this…

This student guide is divided into two sections: "Mice and Men" and "Environmental Balance," and constitutes parts three and four of the first year of the Portland Project, a three-year, integrated high school science curriculum. Part One of the guide deals with topics such as cell, reproduction, embryology, genetics, genetic…

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)

The first three units in this set of mathematical applications cover applications of calculus to economics. Under the title, The Distribution of Resources, are the following: 60-The Lorenz Curve; 61-The Equal Share Coefficient; and 62-The GINI Index. Each of these units contains a set of exercises, a model exam, and answers to both the exercises…

Ten computer simulations for the Apple II are described. Subject areas of programs include: population dynamics, plant competition, enzyme kinetics, evolution and natural selection, genetic mapping, ammonia synthesis, reaction kinetics, wave interference/diffraction, satellite orbits, and particle scattering. (JN)

It has only been since the late nineteenth century that people have understood the mechanics of heredity and the discoveries of genes and DNA are even more recent. This booklet considers three aspects of genetics; time, space, and spirit. Time refers to a sense of history; space refers to geography; and spirit refers to life and thought. Several…
