Describes some of the characteristics of amphibians. Contains teaching activities ranging from a "frog sing-along" to lessons on amphibian adaptations, and night hikes to identify frog calls. Includes reproducible handouts to be used with the activities, and a quiz. (TW)

Describes methods for collection, culture, observation, and making permanent stained preparations of the protozoan vorticella. Suggestions are made for experiments to investigate growth, reproduction, settlement, ecology, feeding, and osmoregulation. (CS)

Reviewed are seven computer software packages including "Frog Dissection Lab Report,""Backyard Birds,""LEGO TC Logo,""Alcohol--Four Interactive Programs,""Windows on Science--Life Science,""Climate and Weather/Our Town Database," and "Weeds to Trees." Discussed are availability, features, strengths, and weaknesses. (CW)

Presents an integrated schoolwide program in which students learn about pet care and the behaviors of 14 unusual animals. Each participating teacher sets up one animal center describing the animal and the animal's habitat. Centers change at the end of each month. Discusses costs and learning benefits of the program.

Some 40,000 animals of various species and sizes are cared for at this facility used primarily for cancer research. (Author/MLF)

Pairing a novel flavor with illness results in the conditioning of aversions to that flavor. This article reported a series of experiments examining the effect of several parameters of prior exposure to the illness on the acquisition of learned taste aversions. (Author/RK)

Does similarity in the location and temporal intensity pattern of the CS and UCS permit more rapid conditioning despite the presence of stimulus pairings in all groups? The following experiments attempt to assess the role of such factors in determining the rate of acquisition of a conditioned emotional response. (Author)

Presents the idea that social systems evolve to increase the genetic fitness of individuals in specific environments. Cites examples of animal behavior and environmental influences that may indicate why different social systems have evolved. (GS)

Presents some solutions to problems commonly encountered in maintaining a classroom aquarium: pH control, overfeeding, overcrowding of tank populations, incorrect temperature settings, faulty introduction of fish into the tank, and the buildup of too many nitrogenous wastes. (PB)

In recent years, the use of laboratory animals for bio-medical research has shown marked increase. Economic and efficient housing is a necessity. This two part report established guidelines for design and selection of materials for conventional animal housing. Contents include--(1) production and breeding facilities, (2) quarantine facilities, (3)…

The position involves providing care for mammals, reptiles, birds, and fish. It is necessary to be familiar with the animals' characteristics, needs, and behavior and possess skill in observing, handling, and controlling them. Different aspects of the WG-4 and WG-5 animal caretaker's position are cited under the categories of general description,…

Recent work has shown that unpredictable and/or uncontrollable events can produce a variety of cognitive, affective, and somatic disturbances to the organism. These disturbances are compared to and found to be quite similar to the symptoms of the classic cases of experimental neurosis described by Pavlov, Gantt, Liddell, Masserman, and Wolpe.…

Results showed that, although adult male monkeys are less active and more stable in their behavioral levels than mates or offspring, they clearly distribute both initiates and responses differently to male offspring, female offspring, mates and infant and adult monkeys from other families. Implications for human father-infant interaction are…
