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.

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…

With the encouragement of parents and teachers, many young people would raise more questions than they typically do about nature. Examples of questions about animals which might lead to creative, thought-provoking discussions and explorations are offered. (CB)

Discusses five- and six-year-old children's conceptions of life and death. Children were questioned about animals, plants, and inanimate objects.

(NH)

Addresses the question of why a dog's eyes appear red and glow when a flash photograph is taken. Conditions for the red-eye effect, light paths involved, structure of the eye, and typical cameras and lenses are discussed. Also notes differences between the eyes of nocturnal animals and humans. (JN)

Eight stump-tailed macaques were reared individually and either given all of their daily social experience in darkness or given half in the dark and half in the light. Results suggest that vision is especially important in the maintenance of assertive behaviors and in the instigation and direction of aggressive behaviors. (Author/RH)

Addresses the problem of cruelty to animals from a research perspective. Studies of possible causes of childhood cruelty to animals are reviewed and common contributing environmental factors are identified. Implications for educators are discussed and directives for detection and prevention of cruelty are suggested. (ML)

Tree frogs are small (2-5 cm) animals which not only interest students but also can be maintained in classrooms for a few days. Characteristics (species, ranges, habitat, reproductive cycle, and locomotion) and housing/care needs are described. Long-term maintenance is not recommended due to the difficulty of providing live food. (DH)

Suggests using crickets for classroom activities, providing background information on their anatomy and reproduction and tips on keeping individual organisms or a breeding colony in the classroom. (JN)
