Described is the production of a simple 30-minute super 8-mm film as a joint student-teacher effort. The film was a study of the ecology of the Santa Ana River. (RH)

Presented are some science activities that children can perform using fallen leaves. (PEB)

Des cribes the techniques for collecting and maintaining the eggs of frogs and toads (JR)

Describes the sturcture and asexual reproduction of the fungus Pilobolus and outlines a number of experiments with this organism that are suitable for secondary school biology students. (JR)

Discusses the three phases of a three-day intensive research study field trip: planning and pre-trip training; actual trip; and post-trip report, research and data organization, and final trip evaluation. Included is a sample program of the limnology field trip taken by the Grafton High School, Wisconsin. (CC)

Presents abstracts of innovative activities of students in grades 7 through 12. Projects include community surveys, student or teacher initiated home/school experiments, scientist-supervised research by high school students, community and school service projects. (EB)

This publication provides the elementary teacher with sequential and developmental objectives in the areas of plants, animals, ecology, and physiology. At least one motivating "hands-on" activity is included for each objective. Age level (5-8, 8-10, 10-12), process emphasized (classification, experimenting, etc.), and group size…

Provided are biological science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments are directed at the student understanding the balance of chemical and physical processes which must be maintained in order to sustain life,…

This laboratory exercise integrates the topics of cell structure, classification of living organisms, and evolution. It is suitable for secondary or college biology courses and was used in an interdisciplinary science course for nonscience majors. (BB)

Described are methods for making Cartesian divers for explaining atomic models utilizing a city planning analogy, a game for reviewing subject matter, the construction of a cell model, an improved diffusion demonstration, and uses of inexpensive glass cutters. (SL)

Discusses the study of rabbits as a science activity with live animals for elementary level students. (SL)

For the secondary school, the author discourages the use of dichotomous keys in favor of a punch-card system. The system is readily constructed by students for use in plant and animal classification. (CP)

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

Describes the life cycle and requirements of midges. Discusses larval substrate preferences, swimming behavior and distribution, developmental rates, temperature tolerances, egg hatching, swarming flights of adults, species composition within a sampling site, and developing a reference collection by rearing larvae.
