Presents the viewpoints of a prominent behavioral scientist concerning the role of the environment in the evolution of behavior. (CS)

Included is information regarding: student construction of Newton's Discs to demonstrate color and of paper helicopters to encourage inquiry; improvising an apparatus demonstrating pressure between two bubbles; animal behavior experiments involving woodlice; two experiments using electronics freezer spray; chromatography of dyes; leaf keys; an…

Listed are criteria to be considered in selecting classroom organisms for suitability in observational studies. Organisms that lend themselves to basic biological principles are also listed. Potential difficulties (safety hazards, habitat replication, confinement, food requirements, teacher's attitude, conservation, escape of nonnative species)…

The artcile answers some questions frequently asked by growing numbers of bird and animal feeders regarding what types of feeders and seed to use and what kinds of birds can be attracted to a given area. It discusses problems which can arise from this enjoyable year-round recreation. (SB)

Describes a constant-temperature observation chamber and includes instructions on constructing the apparatus. Suggestions for use are given as well as problems that might be encountered. (Author/SA)

Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

A program at Moorpark Community College, in Moorpark, California, offers a two-and-a-half-year major in Exotic Animal Training and Management. Emphasis is on the practical, everyday handling and training of wild animals. (LBH)

Compared comprehension of novel communicative signs to assist 2.5- and 3-year-old humans, chimpanzees, and orangutans find hidden objects during a hiding-finding game. Found that children at both ages performed above chance with all signs. No ape performed above chance for any signs not known before the experiment despite three times as many…

Explores the mathematical abilities of human infants compared with various species of animals. Studies indicate that human infants enter the world capable of doing simple mathematical operations. Nonhuman animals can discriminate among sets of objects based on the number of items in each set. Further studies may pinpoint the age at which children…

Provided is a brief description of the biology and taxonomy of British ants. Suggested are a range of exercises which could be used for class or project work in secondary biology classes. Illustrates many ecological, behavioral and physiological points regarding the species of ants found in Great Britain. (Author/CW)

Describes behaviors of the domestic cat in terms of developing students abilities to observe. Discussed are play, territoriality and pecking order, catnip, feral studies, and chasing. (CW)

An indirect procedure that uses the foraging behavior of animals at experimental food patches to address questions in animal behavior is discussed. Suggested projects that include the concepts of predation risk, harvest rates and metabolic costs, missed opportunity costs, and competition are described. (KR)

Presents 2 activities for students aged 8-12 in which students determine (1) whether or not earthworms can see white light; and (2) how an earthworm moves without legs. (MDH)

Presents an activity to determine the identity of animals that owls ingest. Students dissect and examine the contents of "owl pellets" which are the indigestible parts of animals that are regurgitated after eating. Provides instructions for implementing and extending the activity. (MDH)
