Presented is a laboratory exercise that utilizes the natural yeast carbonation method of making homemade root beer to study fermentation and the effect of variables upon the fermentation process. There are photographs, a sample data sheet, and procedural hints included. (Author/MA)

Discussed are the areas where biology teachers can cooperate with teachers of other disciplines. Specific ways in which biology and English teaching can be combined are given, as well as ways to relate the social sciences to biological concerns. (MA)

Described is how to build a solar furnace model. A detailed list of materials and methods are included along with diagrams. This particular activity is part of an audiotutorial unit concerned with the energy crisis and energy alternatives. (MA)

Provided is an activity for student-constructed dichotomous keys that requires nothing more than a pile of shoes. Examples and directions are given. (MA)

Presented is a historical account of science teaching in the United States from the era of Thomas Jefferson to the present. Special emphasis is placed on present demands to reform science teaching from the elementary level through college. Reform policies for consideration are listed in the article. (MA)

This year-long science program involved fifth grade students in the investigation of a meadow pond. Two field trips to collect pond water and organisms were arranged for the beginning and conclusion of the program. Classroom activities were designed to study aquatic organisms, life cycles, populations, and ecosystems. (MA)

Described is the life cycle of the cellular slime molds Acrasiales. Experiments that can be used to explore the aggregation, migration, and culmination activities of the organism are suggested. Laboratory procedures for culturing these slime molds and listings of biological supply houses and literature references are also given. (MA)

Described are the morphology, eating habits, and habitats of three types of Bryozoan colonies. Information on where to collect these organisms and how they can be cultured are included. Suggestions are given for lab experiments that can be done with type three colonies and Euglena. (MA)

The Systems Alternatives Project is an attempt to develop open classroom alternatives within a modular scheduling system. Biology students are given both action and test objectives that emphasize individualization. Structure of the project is detailed and an attempt to analyze the project evaluation data statistically is included. (MA)

Included are over 50 abstracts of papers being presented at the 1977 National Association of Biology Teachers Convention. Included in each abstract are the title, author, and summary of the paper. Topics include photographic techniques environmental studies, and biological instruction. (MA)

Analysis of a summer ecology course emphasizing values clarifying techniques is presented. Pretest and posttest attitude scores indicate a positive increase in attitudes towards ecology. Even a year after the course had been offered, the average attitude scores remained unchanged. (MA)

Described is how a neglected pond was transformed into a useful study area through the efforts of local junior high school students and the community. A chronology of events in the restoration of the pond is included, along with the names of resource personnel and organizations. (MA)

Described is a science field activity that studies the presence of certain aquatic insects, like stoneflies, as indicators of water quality. Equipment, materials, and methods are listed in detail, including suggestions for building certain supplies. Results of previous studies on the Yellowstone River are included. (MA)

Described is the construction and use of an apparatus which applies liquid displacement to the problem of volume determination, giving accurate and repeatable results within 0.1 ml of actual volume measured. The apparatus is easily made from two jar parts, two bottle parts, and a burette. (Author/MA)

Discussed is one teacher's method of teaching students to use various marine and scientific apparati while studying important relationships within the ecosystem. A data retrieval chart is included with questions and problems to ask about the data, along with information on how to interpret the data chart. (MA)
