Describes two methods for rearing small aquatic invertebrates using submerged surfaces in an unfiltered current of water where fish are present. Presents suggestions on how to use the invertebrate communities in the classroom. (JRH)

Equipped with string and paper models, students are able to illustrate the processes of meiosis. (ZWH)

Describes methods of collecting crayfish and maintaining them in the classroom. Also discusses reproduction and molting of crayfish. (MA)

Presents an activity that aims at enabling students to recognize that DNA and RNA are information molecules whose function is to store, copy, and make available the information in biological systems, without feeling overwhelmed by the specialized vocabulary and the minutia of the central dogma. (JRH)

Describes the reorganized introductory cell and molecular biology lecture course at the State University of New York at Binghamton that was designed to address the issues of lack of active student participation and the stress put on memorization rather than analytical skills. Emphasizes teaching the subject historically and empirically…

Presents the process by which a sex education course was proposed, developed, and accepted by a school district. (MA)

Nine lessons which involve the use of marine organisms in the classroom are presented in this seventh-grade biology unit. The unit offers instructors alternative ways of meeting common life science goals. It is not meant to be an extra curriculum added to the normal course load, but was developed to consolidate a group of activities designed for…

Presented is a discussion on why people should study whales. Background information, learning activities appropriate for different subject areas, and whale-related teaching materials are included. (DC)

Describes a 16-week course in marine biology involving a class-coordinated investigation of a subtropical biotic fringing reef of Hawaii. Describes in detail the development of preliminary hypotheses regarding general cause-effect relationships on the reef, and the exploration of specific areas, such as chemical or physical factors. (CS)

Describes a simulation exercise involving an imaginary organism in which students study the effect of predation on allele frequencies, examine the assumptions of the Hardy-Weinberg law, and consider whether the need to survive is a guiding force in evolution. Includes instruction for conducting the exercise. (MDH)

Discusses the relationship between a person's phenotype and allele products, which are different forms of genes. (MKR)

Reports on an interview with John Maynard Smith, one of the most important evolutionary biologists since Darwin. (JRH)

Two exercises on the dispersal of tree seeds by the wind are presented. Procedures, equipment, and analysis for the still air and wind dispersal activities are described. Nineteen references are listed. (CW)
