Alumni of 4-H animal science programs in New Jersey were surveyed (n=52). Participation had a positive influence on life skill development, especially "accepting responsibility." Experience with shows and judging was beneficial to public speaking/job interview skills. Although many were not in animal science careers, they enjoyed related…

Students participating in the Pennsylvania Governor's School for Agricultural Sciences (n=192) studied animal welfare, resource use, and food safety. They ranked food safety as a primary concern. Students with and without agricultural backgrounds showed positive changes in knowledge and perception of issues after the course. (SK)

Several New England groups are breeding and marketing "heritage livestock"--older, multipurpose breeds that are hardier and more disease resistant than modern livestock bred for specialized uses. Hancock Shaker Village (Massachusetts)--a historical museum and working farm--will teach visitors about heritage breeds and sustainable…

Presents an activity on animal adaptation in which elementary school students create their own animals for a given habitat. (YDS)

Discusses parallels between the initial training of young horses and the training of beginning journalists. Looks at the importance of time and energy, patience and discipline in achieving success with both. (SR)

Discusses the reasons for the extinction of amphibians and what makes them so vulnerable. (ASK)

Discusses researchers' attempts to understand the reasons for the declining number of California sea otters. (ASK)

Molar and molecular views of behavior imply different approaches to data analysis. The molecular view privileges moment-to-moment analyses, whereas the molar view supports analysis of more and less extended activities. In concurrent performance, the molar view supports study of both extended patterns of choice and more local patterns of visiting…

This set of studies explored the influence of temporal context across multiple-chain and multiple-successive-encounters procedures. Following training with different temporal contexts, the value of stimuli sharing similar reinforcement schedules was assessed by presenting these stimuli in concurrent probes. The results for the multiple-chain…

The scope and magnitude of our planet's environmental crisis is a sobering reality confronting humanity with the daunting and complex nature of ecological degradation and restoration. The macrocosmic nature of this crisis has not left a species, ecosystem, biome or human society untouched. Moreover, as humanity struggles to gain its bearings at…

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana…

Deep down in the depths of the sea, beautiful fish, mysterious ocean life, and unusual plants glimmer and glow in the eerie atmosphere of an ever-changing ocean. This article describes how, with this vision and a purpose in mind, three teachers pulled open classroom walls and joined forces so their second graders could create a mammoth 30 x 75"…

Oceans are often considered mysterious, fascinating places filled with unique and scary animals. One of the most misunderstood and therefore scariest animals is the shark, yet the whale shark, the world's largest fish, is considered harmless to humans. This student-directed activity involves research, deductive reasoning, and students' own…

Fish dissections are a great way to introduce the concepts of food webs, predator-prey relationships, and ecosystems, but these labs are expensive, messy, smelly, and require a lot of supervision because of the tools involved. The author has developed an inexpensive, safe, and clean alternative where students "dissect" simulated fish…

The effects of contextual shifts on the partial reinforcement extinction effect (PREE) were studied in autoshaping with rats. Experiment 1 established that the two contexts used subsequently were easily discriminable and equally salient. In Experiment 2, independent groups of rats received acquisition training under partial reinforcement (PRF) or…
