Demonstrations, experiments, and classroom activities/materials for middle school science are presented. These include: additive color mixing demonstration; electricity activity and worksheet; atmospheric pressure "magic" demonstration; homemade microbalance; energy from soap bubbles; and a model used to demonstrate muscle pairs and how…

Compared detailed (favoring field dependence and induction) and nondetailed (favoring field dependence and deduction) assignments on biology achievement of grade 10 male students (N=95) over a seven-month period. Detailed assignments, employing pictorial and verbal block diagrams and high structure, significantly enhanced learning among some…

Reviews Outdoor Biology Instructional Strategies (OBIS) materials. The program, consisting of 97 nonsequential biology/ecology activities (games, simulations, crafts, experiments, data analyses), teach environmental concepts and an understanding/appreciation of the environment. Indicates effectiveness of the materials in motivating students,…

Discusses how the science faculty at one rural Massachusetts school responded to the state mandate requiring basic competency testing for all students. The approach taken (includes unit on Connecticut River) does not call for major changes in science course format, only in broadening definition of the responsibilities of science teaching.…

Surveys the attitudes toward teaching held by college biologists at one university. Reports that although keen interest in innovation is expressed, little is done about it. A major problem seems to be information flow, and simple ways of improving this are discussed. (Author/JN)

Instructions (with diagrams and parts list) are provided for constructing an eye model with a pliable lens made from a plastic bottle which can vary its convexity to accommodate changing positions of an object being viewed. Also discusses concepts which the model can assist in developing. (Author/SK)

Provided are two informational sheets, one on puffers and one on carrageen (Irish Moss) and two classroom activities, one on buoyancy in fresh and salt water and one on water surface tension. (DC)

The importance of examining both the natural history of organisms being investigated and numerical data from long-term field experiments is illustrated by describing a long-running field experiment at an English Field Study Council Centre. Sample results are discussed and alternative methods of using field studies in biology instruction are…

Describes a course designed to improve writing ability and ability to use chemical literature, emphasizing course materials, teaching techniques, and effectiveness based on two years of experience. (SK)

Reviews results of a California trial concerning the teaching of evolution in public school classrooms. Also lists recent legislation in the states of Florida, California, Minnesota, South Dakota, Kansas, Illinois, Iowa, Texas, and Arkansas. (CS)

Descriptive information relative to the historical background of the development of a new, uniform secondary school biology curriculum in China is provided. This curriculum, introduced in 1979, is designed to contribute to the achievement of national goals aimed at the modernization of agriculture, industry, defense, and science and technology.…

Describes a method to allow direct observation of a chick embryo development from three days to about 17 days of incubation, by culturing the entire embryo in a petri dish. (DS)

Describes ways platyfish can be utilized in biology activities and experiments. Includes an account of the animals' care, unique anatomical characteristics, reproductive behavior, and genetics. (DS)

Provides examples of several classroom activities utilizing the American horseshoe crab (Limulus Polyphemus), including raising fertilized eggs, fertilizing eggs in vitro, and testing water samples. Includes background information on the natural history, life cycle, and breeding habits of this animal. (DS)

A Higher Education Research Institute pilot study of the reputations of undergraduate departments is discussed. The intent of the study was to quantify the subjective judgments of undergraduate departmental quality and to investigate the association of ratings on different criteria and for different types of institutions.
