Discusses an art activity that has students create pictures in which they first trace a chameleon pattern and then add camouflage to conceal the chameleon. Explains that different materials and techniques are used for students in grades k-1 and 2-5. (CMK)

Studied whether 41 Japanese 6-year olds' voluntary participation in animal care activities in school was associated with children's understanding of animal care procedures. Found that children experienced in such activities had better understanding of animal care procedures than those who were not, but levels of participation were not associated…

A study investigated the number of guide dog teams that have been trained and are active in the United States from 1993-1999. Results found 1,556 guide dog teams were trained in 1999, an increase of 7%, and that there were 9,000 active teams, an increase of 10% since 1993. (Contains eight references.) (CR)

Explains that if students want to depict predatory animals in works of art, they need to learn the shapes of the animals and their habitats. Discusses four artworks (reproductions included) that depict predatory animals by Darrel Austin, Ando Hiroshige, Antoine Louis Barye, and John Singleton Copley (CMK)

Describes how drawing can be used as a tool to help students develop and document more complex understandings not often used in science instruction. Explores how drawing can be used to learn about animals. Includes student illustrations. (SAH)

A study of 192 high school students participating the Pennsylvania Governor's School for Agricultural Sciences found that, regardless of previous agricultural experience, students had more positive views of agriculture and increased agricultural knowledge after completion of the 5-week course. The effects were greatest for students without…

Focuses on David Bates and his artwork entitled "Blackwater I." Includes background information, activities based on the artwork, and a reproduction of the painting. Describes the painting, focusing on how it is like and unlike folk art. (CMK)

Peter B. Dews played a significant role in shaping the distinctive characteristics and defining the underlying principles of the discipline of behavioral pharmacology. His early and sophisticated use of schedules of reinforcement in the 1950s, incorporated from research in the experimental analysis of behavior and integrated into the discipline of…

Pigeons' choice in concurrent chains can adapt to rapidly changing contingencies. Grace, Bragason, and McLean (2003) found that relative initial-link response rate was sensitive to the immediacy ratio in the current session when one of the terminal-link fixed-interval schedules was changed daily according to a pseudorandom binary sequence (e.g.,…

In this study, the authors examined the effects of a conservation education camp program offered through one zoo education department. The conservation education program included 4 levels of camps with increasing levels of animal husbandry. Campers rated their conservation knowledge, attitude, and behavior prior to, immediately after, and 1 month…

In this article, the author discusses the High School Scalloped Hammerhead Shark Tagging Program in Hawaii which is an example of a successful partnership research collaboration. High school students and teachers worked with biologists from the University of Hawaii-Manoa (UHM) to conduct research on the life history of scalloped hammerhead sharks…

Animal cell culture is a core laboratory technique in many molecular biology, developmental biology, and biotechnology laboratories. Cell culture is a relatively old technique that has been sparingly taught at the undergraduate level. The traditional methodology for acquiring cell culture training has been through trial and error, instruction when…

In this activity students examine burrow casts to learn about burrowing animals and practice their math skills. Students compute the volume and average circumference of a burrow. They also determine whether a relationship exists between burrow volume and the size of the organism that created it. Students use science as inquiry as they analyze and…

A simple and effective field exercise that demonstrates factors affecting predation on bird nests is described. With instructor guidance, students in high school biology or college-level biology, ecology, animal behavior, wildlife management or ornithology laboratory courses can collaborate to design field experiments related to nest depredation.

As the articles in this issue attest, U-shaped curves in development have stimulated a wide spectrum of research across disparate task domains and age groups and have provoked a variety of ideas about their origins and theoretical significance. In the authors' view, the ubiquity of the general pattern suggests that U-shaped curves can arise from…
