Presents two techniques involving simple and inexpensive demonstrations: (1) explains how pressure inside cells gives them mechanical strength, and (2) shows how water can be pulled up stems. Both can be adapted to suit a variety of levels of instruction. (PR)

Describes how lectures, laboratories, and role playing can be used to introduce students to the importance of water quality of water used for plant growth. (PR)

This thesis reports on the research of 25 plants, used as herbal remedies since the 1800s by the author's Native American ancestors (the Day family) and the Cherokee tribe. The plants were identified in four state parks in southwestern Indiana. Information sources included the research literature, articles on Cherokee herbal remedies, and…

Studies the perceived effectiveness of four student projects involving videotape production, computer conferencing, microcomputer simulation, and rapid-cycling Brassica breeding for undergraduate plant breeding students in two course offerings in consecutive years. Linking of the computer conferencing and video projects improved the rating of the…

Describes a simulation exercise developed for an introductory biology course for nonmajors. The simulation focuses on the control of western spruce budworms in forests of the western United States. A nonlinear, multivariate simulation model is used. (PR)

Explains how computer database technology can be used in the herbarium and be a useful aid in teaching botany and plant taxonomy. (PR)

Uses the U.S. General Land Office Survey as a source of data for reconstruction of local presettlement vegetation patterns in the United States. Data serve as a basis for an introductory biogeography course at Indiana University, Indianapolis. Includes field exercises, questions, and tables of frequency of witness-trees records. (NL)

Uses ethnic recipes to analyze new and old world post-Columbian exchange of domesticated plants and animals in an introductory cultural geography course. Describes student research projects and includes tables of domesticated plants and animals by region and use. Also provides two student sample recipes with lists of ingredient origins. (NL)
