Describes a demonstration experiment illustrating rotation of grains process of metamorphic rock formation utilizing clear gelatin blocks. (SL)

Describes a laboratory exercise to demonstrate enzyme activity using gelatin and meat tenderizer. The exercise is adaptable to any grade level. (MA)

Presents some simple demonstrations that students can construct for themselves in class to learn the difference between diffusion and convection rates. Uses cabbage leaves and gelatin and focuses on diffusion in ungelified media, a quantitative diffusion estimate with hydroxyl ions, and a quantitative diffusion estimate with photons. (DDR)

Presents a laboratory activity on enzymes. Uses common items found in the supermarket that contain protease enzymes, such as contact lens cleaner and meat tenderizer. Demonstrates the digestion of gelatin proteins as part of enzymatic reactions. (Author/SOE)

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (CW)

Background information, procedures, equipment, and results for two experiments are presented. The first involves the measurement of the mass-average and degree of coiling of polystyrene and is interpreted by the full mathematical theory of light scattering. The second is the study of transitions in gelatin. (JN)

In this activity, students build a city out of sugar cubes, bouillon cubes, and gelatin cubes. The city is then put through simulated earthquakes to see which cube structures withstand the shaking the best. This activity requires a 50-minute time period for completion. (Author/SOE)

Provides specific information on varying photographic materials and processes to aid archivists and curators in preserving photograph collections. Preservation problems related to major types of silver prints on paper (salt, albumen, collodion, gelatin) and to the silver image (oxidation, silver sulfide) are covered. Twenty references are cited.…

Provides two demonstrations: (1) electrolyte migration of ions using colored ions which cross a strip of gelatin allowing for noticeable migration; and (2) photochemical reduction of Fe+3 by the citrate ion. Points out both reactions can be done in a Petri dish using common lab materials. (MVL)

In this article, a practical demonstration suitable for any biology college classroom is presented. With the examples of a complex biological specimen (slug's radula) and a simple reference specimen (electron microscopical grid imprint in gelatin), both of which can be easily prepared, the capabilities of two imaging modes commonly used in optical…

Using environmental materials (such as the phone book and placemats from fast food restaurants) can be a motivating way to teach learning disabled students skills and concepts, as shown in an approach to reading, math, science and nutrition, and social studies instruction using a JELL-O brand gelatin box. (CL)

At all levels of instruction commonplace items such as fruit, gelatin, golf and tennis balls, and sugar cubes can be used to demonstrate geographic concepts such as earth-sun relations, locative grid, structure of the earth, glaciation. Tactile and visual demonstrations in which students participate are more effective than other alternatives. (NH)

Redgram (Cajanus cajan L.) extracts have been analyzed for the protease inhibitors using a new, sensitive, simple, and rapid method for detection of electrophoretically separated protease inhibitors. The detection involves equilibrating the gel successively in the protease assay buffer and protease solution, rinsing the gel in assay buffer, and…

Developed as part of the Marine Corps Institute (MCI) correspondence training program, this course on salads, sandwiches, and desserts is designed to provide Marine food service personnel with a general background in the proper techniques for the preparation of these items. Introductory materials include specific information for MCI students and a…

Activities which can be done with items purchased in supermarkets form the basis of this book. The activities are arranged into sections by type of item; breakfast foods; dried foods; soups; baking ingredients; gelatin; condiments; coffee; salad dressing; dairy products; meats; cleaning supplies; cookware; juices; picnic supplies; paper towels;…
