Described is an integrated investigation to study interdependence among ants. The instructional sequences and results of this activity are provided. A matrix is given which details the content covered in this investigation. (CW)

Presented is a set of mathematics problems associated with the characteristics, production, and consumption of chicken eggs. Student assignment sheets are included. (CW)

Describes efforts of the InterTribal Bison Cooperative (Rapid City, SD) to reintroduce the buffalo for cultural purposes to American Indian reservations. Explains how the buffalo's return is contributing to community wellness. Discusses career opportunities for both Native and non-Native people in buffalo management. (LP)

Describes some alternatives to dissection offered to teachers through the National Anti-Vivisection Society (NAVS) and other sources. These include models, CD-ROMs, and software that enable students to click on scalpels, scissors, and other instruments to cut through videotaped specimens. Also details the Dissection Hotline and the Dissection…

Investigates the attitudes and values that children and adolescents hold with respect to nature and the patterns of reasoning with which they are expressed. Outlines current positions in environmental ethics, discusses difficulties in applying contemporary theories of moral development to the problem, and summarizes preliminary results of the…

Describes two new exercises in classical conditioning that use earthworms and houseflies. The animals are available year-round and pose no risk to the students or instructor. The conditioned stimuli are odorants. These elicit a conditioned response of contraction in worms or proboscis extension in flies. (MJP)

Introduces Project WRITE (World Resources for Integrated Thematic Education). Features six science-based units that include "American Revolution: People and Technology", "A Look Inside Ourselves", "Westward Ho!", "Animals and Humans Living Together", "Environmental Awareness", and "1800s: The…

Recommends a number of investigations using video-capture and two readily available, non-pathogenic larval Digeneans with contrasting life cycles and behavior. The activities support the hypothesis that parasites exhibit behavior that increases their chances of a host infection. (DDR)

The chief purpose of this activity is to strengthen students' understanding of concepts of floatation such as surface area and pressure (weight per unit area) via snowshoes. Students brainstorm, make predictions, perform calculations, and practice communication skills through interviewing elders and experts. This activity lets students see the…

"Chronicle of Higher Education" presents an abundant source of news and information for college and university faculty members and administrators. This April 15, 2005 issue of "Chronicle for Higher Education" includes the following articles: (1) "M.A. Students as Pledges" (Hengen, Nicholas); (2) "It's All An Illusion" (Schweber, Simone); (3)…

Generalizing or making claims that extend beyond particular situations is a central mathematical practice and a focus of classroom mathematics instruction. This study examines how aspects of generality are produced through the situated activities of a group of middle school mathematics students working on an 8-week population-modeling project. The…

In this paper, we draw on the concept of "lifescape" (Some and McSweeney, ILEIA Newsletter, ETC Leusden, The Netherlands, 1996; Howorth, Rebuilding the Local Landscape, Ashgate, Aldershot, 1999) to capture the spatial, emotional and ethical dimensions of the relationship between landscape, livestock and farming community and to elucidate…

Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist…

This article presents an example of a versatile multi-solution problem that can be used right across the primary years. The basic problem is: "Noah saw 16 legs go past him into the Ark. How many creatures did he see?" Any even number can be used, although, 2 legs allows only one answer and with 16 legs there are already 14 different…

These Illinois skill standards for the agricultural laboratory and field technician cluster are intended to serve as a guide to workforce preparation program providers as they define content for their programs and to employers as they establish the skills and standards necessary for job acquisition. They could also serve as a mechanism for…
