Describes a field-biology research project conducted at Coos Bay, Oregon by high school students attending the summer sessions at Terramar Field Science Facility during the summer of 1972. Discusses the value of this type of environmental survey for both the students and the community. (JR)

Describes how to construct a locust cage from two plastic aquaria and four coffee jars with plastic lids. Its advantages over a conventional locust cage include the inexpensive cost, lack of breakable glass, ease of cleaning, and visibility from all angles. (JR)

Describes a high school summer program in field ecology designed to give students a first-hand understanding of their own biotic environment, to acquaint them with the organisms, relationships, and complexities of local habitats, and to introduce them to the methods and techniques of discovering and gathering information about nature. (JR)

Describes an information retrieval system in entomology which could also be used for other biological literature. With the examples of coding information into the system, a user might get some idea of how to search and what kind of information might be found. No cost analysis for running the program is included. (PS)

Describes computer assisted simulation model for studying problems of an ecosystem. Example used is algae-Daphnia-predator system. Problems for students to solve in this ecosystem are described. (PS)

Discusses socioeconomic problems of pet population explosion and recommends the conduct of educational programs and the implementation of surgical sterilization as a short-term answer to dog and cat control. Also considered are problems of using chemical contraceptives in human population control. (CC)

Reports degree of relationship between assessments of teachers' procedural and verbal behavior made independently by teacher self report, student checklists, and the observations of an outside observer. (AL)

The effects of the menstrual cycle on the performance, heart rate, and body temperature of female athletes are discussed. Biological causes of menstrual problems such as dysmenorrhea and amenorrhea are explained. Research indicates that the higher the level of training achieved, the less effect each cycle phase has on physical performance. (PP)

Described are activities which utilize marine science subjects. These include: assemblage, bas-relief, batik, collage, mobile, montage, paper-mache, and play-dough activities. Includes a list of general suggestions for teachers using aquatic art activities in the classroom. (JN)

Provided is a high school activity in which students observe the filter feeding of barnacles and the effects of a variety of changing parameters upon their feeding process. Includes list of materials needed and procedures necessary to accomplish the activity. (JN)

Various topics on the biochemistry of genetic manipulation are discussed. These include genetic transformation and DNA; genetic expression; DNA replication, repair, and mutation; technology of genetic manipulation; and applications of genetic manipulation. Other techniques employed are also considered. (JN)

The log C-pH diagram is a useful means of displaying quantitatively the many variables (including temperature) that determine acid-base equilibria in biological systems. Presents the diagram as extended to open/closed biological systems and derives a new water-ion balance method for determining equilibrium pH. (JN)

Effects of varying the usual biology-chemistry course sequence were studied by comparing students' scores on the Natural Science Reading Test of the American College Test (ACT). Results showed that it made little difference whether college preparatory students at two New Orleans (Louisiana) high schools took chemistry before biology or vice versa.…
