Describes the construction and observation of beehives. (SL)

Describes an activity to simulate enzyme activity. Discusses the processes demonstrated and variations in the assembly line method. (CW)

Discusses between-species variation in adaptation of the photosynthetic mechanism to cope with wide fluctuations of environmental water regime. Describes models for water conservation in plants and the role of photorespiration in the evolution of the different pathways. (CW)

Results from a national assessment of science conducted by the Minnesota Science Assessment and Research Project in 1981-82 are presented. The achievement of 13- and 17-year-olds on biology items, their attitudes about science and science classes, and comparisons with data from 1976-77 are discussed. (MNS)

Describes an individualized exercise designed to acquaint students with the influence of biological sciences on culture, economics, politics, and social systems. The exercise requires student investigation and reporting on a socially controversial science related subject. (SL)

Described is a two year, seven unit, interdisciplinary secondary biomedical program designed for students interested in pursuing health-related careers. (SL)

Discusses the use of and recommends a new direction for laboratory work within the context of teaching human ecology for science and social science teachers and compares traditional and human ecological approaches to science laboratory work. (CS)

Examined two questions: (1) Do high school students perceive the physical sciences as more masculine career fields than the biological sciences; and (2) what is the influence of coeducation on these sex-stereotyped positions? Utilized a questionnaire requiring a rating of 45 career fields as masculine or feminine. (DS)

Described is an advanced biology class project involving study of the effects of organic pollution on an aquatic ecosystem from an sewage treatment plant overflow to evaluate the chemical quality and biological activity of the river water. (DS)

Described is a marine science course offered to high school biology teachers. The course objectives were designed to introduce teachers to a marine science subject that could be used in the secondary science classroom and laboratory and to create an awareness of the issues surrounding the marine sciences. (DS)

The use of pesticides in the schools is discussed. Some potential hazards include seeds dressed with fungicide/insecticide mixtures, fumigation of animal houses and greenhouses, and storage and disposal of pesticides. (SA)

Ideas related to including ethology in high school biology programs are given. The methods of ethology and tips on how to communicate observations are briefly explained. (SA)

Discusses the energy processes required to sustain life. Diffusion, oxygen transport, oxygen in arterial blood, and carbon dioxide transfer are the topical subdivisions discussed. (SA)

Describes the use of mud dauber wasp nests in laboratory activities in ecology and behavior and life science classes. Provides students with an opportunity to develop and practice basic skills including dissection, identification, observation, measurement, and communication. Discusses the life of mud daubers, obtaining and storing nests,…

Presented are several ideas for projects involving ladybird beetles. Discussed is background information about the insects; and projects involving life histories, intra-specific variation, taxonomy, genetics, behavior, ecology, habitat surveys, population biology, and overwintering biology. Lists 12 references. (CW)
