Explains how sweet potato roots can be used for plant tissue culture for biology laboratory instruction. (PR)

A diffusion simulation is described in which the dispersion of potato beetles in a given problem is traced on hexagonal grids. (MNS)

Explains how the surface of a freshly sliced potato can be used for a variety of enzyme action experiments including the influence of pH on enzyme action, the enzyme denaturation potential of boiling water, the inhibition of enzymes by heavy metals, and the effects of salt concentration on enzyme effectiveness. (PR)

Describes an experiment in which groups of students in a plant tissue culture course worked together to test application of the Skoog-Miller model (developed by Skoog and Miller in regeneration of tobacco experiments to demonstrate organogenesis) to sweet potato root explants. (ZWH)

The classroom care and maintenance of terrestrial isopods is described. Includes illustrations of isopod external anatomy, a potato trap for collecting isopods, and a constructed habitat for raising isopods. (MA)

The "hot potato technique" (HPT) is described as an effective way to engage high school English-language students in class discussions. HPT involves using newspapers and magazines to stimulate participation. (LB)

Reports two electrochemical demonstrations. Uses a hydrogen-oxygen fuel cell to power a clock. Includes description of methods and materials. Investigates the "potato clock" used with different fruits. Lists emf and current for various fruit and electrode combinations. (ML)

Fourth and fifth grade students at Bulman Elementary School, Redford, Michigan, learn economics concepts by selling potato chips: company stocks are sold and part of the profit is invested in a student-run bank which has checking accounts and issues monthly statements. (AV)

Describes an experiment designed to help students understand the concepts of osmosis and surface area to volume ratio (SA:VOL). The task for students is to compare water uptake in different sizes of potato cubes and relate differences to their SA:VOL ratios. (JN)

This manual has been designed to guide courses on potato production sponsored by the International Potato Center (CIP) in Lima (Peru). It describes the CIP Course Evaluation System that is presently used and provides guidelines on how to use feedback more effectively for improving training. CIP evaluations are largely formative. The CIP focuses on…

High-school art teachers and student volunteers from advanced studio classes worked with trainable mentally retarded students on art projects such as abstract design paintings and note cards and potato-printed placemats. The impact of the experience on the handicapped students, the student aides, and the teachers is noted. (JDD)

Consists of a reading assignment and questions for students about Christopher Columbus' voyages. Provides details on how Columbus brought the potato to Europe from the Americas and how sugar, new diseases, and the horse got to the Americas. Argues that Europe would have been different, and poorer, without Columbus. (SG)

Thin slices of potato can be used to demonstrate the presence of protein, carbohydrates, and nucleic acids at the cellular level. Procedures and materials are provided for these simple tests. Also indicates that the presence of fat can be readily seen by staining avocado with Sudan red or Sudan black. (Author/DH)

Discusses teaching about Christopher Columbus and the contact between the Americas and the Old World. Suggests that most history texts are correct in the information they include but leave much out. Describes a museum exhibit focusing on disease, corn, the potato, the horse, and sugar as agents of change resulting from the Columbian contact. (DK)

This booklet, one of a series featuring the Canadian provinces, presents a brief overview of Prince Edward Island and is suitable for teacher reference or student reading. Separate sections discuss geography, climate, history, early trade, development, agriculture, the potato industry, forests, fisheries, aquaculture, industry, tourism, energy,…
