Presents activities designed to build an understanding of why the physical characteristics of small animals such as the water strider, water spider, and the basilisk make it possible for the animals to use the surface tension of water to their advantage. Discusses the concept of geometrical scaling. (JRH)

The author recounts childhood interactions with animals in the "wild" and how these experiences can enrich the lives of both children and adults. (LZ)

Discusses contributions of E. O. Wilson and others to the development of sociobiology. Considers sociobiology's origins, the study of social behavior, the inclusive fitness theory of behavior, haplodiploidy, reciprocal altruism, ecological perspectives, species richness, social evolution, societal explanations for infanticide, sociobiology and the…

In three experiments, children were asked whether animals, plants, and artifacts that had been damaged could heal through regrowth and whether a person could mend them. Four-year olds realized that both animals and plants could regrow and that artifacts had to be fixed by humans. Three-year olds were less knowledgeable than four-year olds. (MDM)

Examines one component of an African Grey parrot's monologue behavior, private speech, while he was being taught new vocalizations. The data are discussed in terms of the possible functions of monologues during the parrot's acquisition of novel vocalizations. (85 references) (GLR)

College and university public relations officials need to be aware of the potential problems associated with institutional research programs using animals and conflicts with animal welfare activists. Steps to take include anticipating and planning for a crisis, knowing campus research projects, and educating the various constituencies affected,…

Explores themes relating to human transition as they appear in "Charlotte's Web" and four other stories using pigs as a subject. Discusses the motifs common to all these texts that recur in the film "Babe." Considers how the cycle of life and death is ceaseless, and pigs symbolize the necessary transitions that people must all…

Presents an activity that is foolproof for children to collect and observe soil animals, alive and in the animals' own environment. (ASK)

Describes the inexpensive and safe method of using roundworms in the classroom or laboratories. Because parasitic infections are so common, students should learn about worms. Provides statistics on just how many people have a worm infection in the world. Explains how to study living nematodes, and obtain and use earthworms. (Contains 13…

Five experiments tested the development of conceptual categories by familiarizing infants to objects in a category and presenting them with an object in a different category. Infants' responses indicated that infants at 7 to 11 months categorized animals, vehicles, and furniture; at 11 months, plants and kitchen utensils; and at 9 to 11 months,…

Comparison of 184 animal science students in modified alternating day block schedule with 136 in 9-week accelerated block schedule showed that higher-order thinking skills achievement was less than half of the passing standard. Higher- and lower-order skills performance of modified schedule students was superior, which may be explained by teacher…

Explains a study that assesses students' ideas about animals. Evaluates textbooks and trade books according to the identifications and words they use. Discusses student responses from different grade levels on the classification of animals and identifying what is an animal. Summarizes the results of the study and makes recommendations on the…

Reflects on middle school students' interest in stamp collections and considers science-related stamps as a good source for a classroom display. (YDS)

Two experiments are reported in which the ratio of the average times spent in the terminal and initial links ("Tt/Ti") in concurrent chains was varied. In Experiment 1, pigeons responded in a three-component procedure in which terminal-link variable-interval schedules were in constant ratio, but their average duration increased across components…

In a continuation of the conversation with Fitch, Chomsky, and Hauser on the evolution of language, we examine their defense of the claim that the uniquely human, language-specific part of the language faculty (the ''narrow language faculty'') consists only of recursion, and that this part cannot be considered an adaptation to communication. We…
