This transition, observed with an inexpensive ultraviolet photometer, is a potentially useful experiment for an advanced freshman class because it introduces several concepts of general physical interest. (DF)

Provides laboratory design and materials needed to have students prepare cell cultures. Necessary techniques are explained along with an outline of some basic and advanced exercises. (DS)

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)

This paper includes a general account of the biology of the brine shrimp, instructions on how the organism may be cultured, the results of some experiments on the ecology and population biology of the species, and some suggestions for further studies. (Author/CW)

Presented is an exercise for high school students which illustrates the principle and practice of measuring energy flow through a community. Included are worksheets, instructions, a flow diagram, and a list of ecosystem parameters. (Author/CW)

Appropriate for secondary school botany instruction, this study guide focuses on the important roles of plants in human lives. Following a rationale for learning the basic skills of a botanist, separate sections discuss the process sunlight undergoes during photosynthesis, the flow of energy in the food chain, alternative plant lifestyles, plant…

This series of interdisciplinary activities, some of which are done outside the classroom, promotes awareness of the relationship between nature and man. The booklet contains student worksheets, resource lists, a bibliography, and units on ecology and tree conservation. Lessons, which are short and varied, cover topics such as awareness,…

This publication provides the elementary teacher with sequential and developmental objectives in the areas of plants, animals, ecology, and physiology. At least one motivating "hands-on" activity is included for each objective. Age level (5-8, 8-10, 10-12), process emphasized (classification, experimenting, etc.), and group size…

Provided are biological science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments are directed at the student understanding the balance of chemical and physical processes which must be maintained in order to sustain life,…

This is level two in a series of eight study guides in the field of environmental education. Intended for the middle elementary grades, this guide stresses awareness and interrelatedness of living things, their needs, meeting these needs, and man's moral responsibility. Through many suggested activities, students are helped to gain an…

The purpose of this textbook is to provide junior high school students with the knowledge they will need to effect the changes that must be made for survival, to provide an environment that can sustain and flourish life, and understand and appreciate the aesthetic, social, and scientific implications of environmental problems. Organized around…

Discusses eighteen minicourses developed from material contained in BSCS biology yellow, green, and blue versions. (BB)

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…
