Historical uses of Arum maculatum (L.) are summarized. Temperature changes during spadix maturation, spathe uncurling in the presence of flower tissue, indol-3-y1 acetic acid, and gibberellic acid are investigated in the laboratory. Dilute solutions of both phytohormones cause significant spathe uncurling. Further investigations are suggested.…

Experiments by secondary school students which inflict pain and suffering are described. NSTA policy regarding the use of live animals is presented. An argument for the use of animals in research is given along with a recommendation by the author that animal projects should show a reverence for life. (AJ)

The article provides an example of a project in physics concerning clocks in which gifted pupils engage in high-level problem solving while developing technical knowledge and appropriate scientific methodology. Drawings illustrate the principles taught by the project. (Author/DB)

Methods of investigating plant root growth developed for research purposes can be adopted for student use. Investigations of the effect of water table level and of ethylene concentration are described, and techniques of measuring root growth are explained. (Author/ML)

Using many different media, students can turn leaves into images which can be used for study, bulletin boards, collections, and identification. The simple techniques described include pastel printing, smoke prints, ink or tempura printing, bleach printing on t-shirts, ditto machine printing using carbon paper, and making cutouts. (DH)

Describes the rationale for and objectives of a strategy in which students display projects in lieu of a final examination. Although no grading is attached to the "walk-through," participation is required for the course grade. Sample student projects reflecting the variety of display formats are also described. (JN)

Described are research topics, activities, and experiences that were a major part of a two-week workshop sponsored as a starting point in the study of Bicentennial Science. (EB)

A unit on energy is a perfect opportunity to use an interdisciplinary approach with a range of grade levels. This blueprint describes the needs of one such program and covers developmental strategies step by step. Each activity is categorized according to grade level. Topics include: (1) "Getting Organized," which discusses selecting activities…

Suggests that the Friedel-Crafts reaction, used for synthesizing a wide range of aromatic compounds, is an ideal vehicle for extended senior high school project work in chemistry. Provides a theoretical discussion of the reaction, suggests a number of suitable investigations, and outlines the experimental details. (JR)

Sets forth guidelines for students interested in doing research. Includes requirements for the research projects, steps in project work, style and format for the report, and a list of references. (DF)
