This pamphlet suggests ways to grow garden vegetables in common household containers. A chart of cultural requirements of common vegetables is accompanied by a teacher's guide discussing the process skills and understandings which can be taught using the minigarden technique. A vocabulary list, a list of materials and supplies, and the methods by…

THE USE OF AUDIOTUTORIAL TECHNIQUES FOR TEACHING INTRODUCTORY COLLEGE BOTANY IS DESCRIBED. SPECIFIC PRACTICES USED AT PURDUE UNIVERSITY TO ILLUSTRATE DIFFERENT FACETS OF THE APPROACH ARE ANALYZED. INCLUDED ARE INDEPENDENT STUDY SESSIONS, SMALL ASSEMBLY SESSIONS, GENERAL ASSEMBLY SESSIONS, AND HOME STUDY SESSIONS. ILLUSTRATIONS AND SPECIFICATIONS…

This unit is a part of a series of materials produced by a project to develop locally applicable class, lab, and field materials in ecology and social studies for Guam junior and senior high school. While the materials were designed for Guam, they can be adapted to other localities. This unit is designed to interest the student in growing plants…

A brief summary of the year's activity. (BB)

A discussion of some of the difficulties and procedures in translating classical quotations occurring in a modern text. Some of the topics covered are: use of published translations, transliteration from ancient Greek, and non-classical idioms such as medieval and botanical Latin. (AMH)

Discussed are the seed dispersal mechanisms of six different plants: big-leaf maple, pincushion tree, tree of heaven, squirting cucumber, digger pine, and bull thistle. Elaborate color and black-and-white drawings illustrate the text. (MA)

Updates knowledge on nitrogen fixation, indicating that investigation of free-living nitrogen-fixing organisms is proving useful in understanding bacterial partners and is expected to lead to development of more effective symbioses. Specific areas considered include biochemistry/genetics, synthesis control, proteins and enzymes, symbiotic systems,…

Discusses various topics and issues related to the scientific enterprise in Cuba. Notes that Cuban science is emphasizing biotechnology and research on the island's chief crop (sugarcane), although hampered by limited personnel and lack of modern laboratory equipment. (JN)

List of materials needed, procedures used, and results obtained are provided for two demonstrations. The first is an inexpensive and quick method for demonstrating column chromatography of plant pigments of spinach extract. The second is a demonstration of cathodic protection by impressed current. (JN)

Examines major lines of thought leading to what is meant by plant biotechnology, namely, the application of existing techniques of plant organ, tissue, and cell culture, plant molecular biology, and genetic engineering to the improvement of plants and of plant productivity for the benefit of man. (JN)

Study of buried seed banks (viable seeds deposited in the soil near parent plants) provides a relatively easy way of determining cumulative effects on seed production and species' altitudinal limits. Sites, methods, validity, interpretation, problems of collection on a mountain, and germination techniques are discussed. (Author/DH)

Four papers are reviewed. They include a description of how instructional modules and small group problem-solving (PS) in a second-year plant anatomy course produced excellent PS skills and various ideas on PS in the context of chemistry. Also reviews guided-design as a strategy to help develop PS skills. (JN)

Discusses: (1) the fluid mosaic membrane structure and light reactions of photosynthesis as exemplified by the Hill and Bendall "Z-scheme"; (2) the arrangement of light-harvesting pigments, electron transport components, and ATP synthesis on chloroplast membranes; and (3) how these topics are treated in A-level textbooks. (JN)

Provides: (1) background information on trees, focusing on the parts of trees and how they differ from other plants; (2) eight activities; and (3) ready-to-copy pages dealing with tree identification and tree rings. Activities include objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Background information, list of materials needed, procedures used, and discussion of typical results are provided for an experiment on the thin layer chromatography of chlorophyll pigments. The experiment works well in high school, since the chemicals used are the same as those used in paper chromatography of plant pigments. (JN)
