Described are nutritional studies that can be incorporated into elementary biology courses. Included are suggested experiments concerning physical change, chemical change, and microbiological change. (SL)

Presents the following three biology notes: (1) a low cost variable temperature incubator; (2) projects on the ecology of freshwater mussels (Unionidae); and (3) studies on urease. (HM)

Provides a listing of articles and papers published in 1976 relating to various fields of biology and presents various biological science activities. (SL)

Plant material can be used for classroom investigations of factors influencing infection. Plant responses to infection can be used as teaching models for animal as well as plant diseases. Three activities are discussed. (Author/CW)

Discusses alternative theories to evolutionism. Five theories are mentioned, but most attention is given to the steady state theory of species which the author considers the most suitable partner for Darwinism in O- and A-level biology courses in the United Kingdom. (HM)

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)

Describes 36 science activities. Topics include: osmosis, fermentation, anhydrobiotic organisms, breathing monitors, trypsin, weeds, amyloplasts, electrolysis, polarimeters, ethene ripening of fruit, colorimetry, diffusion, redox reactions, equilibria, acid-base relationships, electricity, power, resonance, measurement, parallax, amplifiers,…

Contains three articles designed to help practitioners with practical assessment for the GCSE. Articles include: "GCSE Biology Practical Assessment--Can the End Justify the Means?"; "Investigating the Effect of Catalase: GCSE Assessment Practical"; and "An Experimental Design for GCSE Physics." (CW)

Outlines the role of the main organisms involved in woodland decomposition and discusses some of the variables affecting the rate of nutrient cycling. Suggests practical work that may be of value to high school students either as standard practice or long-term projects. (CW)

Addresses several questions related to British secondary students' choices in science, particularly as they relate to gender differences. Cites several national surveys that suggest that girls tend to choose biological science courses, while boys choose physical and technological science courses. (TW)

Assesses whether British secondary schools have altered the scope and pattern of science course offerings. Data on science entry examinations indicate that increases in selection of balanced science courses have occurred. Gains in female entries are noted. (ML)

Describes equipment, experiments, and activities useful in middle school science instruction, including demonstrating how strong paper can be, the inclined plane illusion, a simplified diet calculation, a magnetic levitator, science with soap bubbles, a model motor and dynamo, and a pocketed sorter for safety glasses. (SK)

Presented are 25 short articles which represent a variety of topics. Included are laboratory exercises, games, demonstrations, models, activities, teaching methods, notes regarding procedures and updates of scientific information. (CW)

Describes 20 teaching activities and experiments appropriate for use with various secondary school science classes. Instructional activities include the study of catalase, raising bees, a game about equilibrium, spectrometers, lead iodide, resonance, graphing, and electromagnetic waves. (TW)

Presented are five ideas for A-level biology experiments using a laboratory computer interface. Topics investigated include photosynthesis, yeast growth, animal movements, pulse rates, and oxygen consumption and production by organisms. Includes instructions specific to the BBC computer system. (CW)
