Youth explore more about dog health, nutrition, and care, genetic problems, population control, showmanship, training, ethics and budgeting. Youth who engage in this curriculum will develop essential dog project skills such as selecting a dog; investigating breeds; appreciating dogs' places and roles in society; practicing grooming, fitting,…

Describes an interdisciplinary minicourse on dinosaur fossils, morphology, ethology, and energetics. Suggests and provides examples of hands-on activities for junior high school- through college-level students. (DS)

"The Complete Guide to Service Learning" is the go-to resource in the fast-growing field of service learning. It is an award-winning treasury of service activities, community service project ideas, quotes, reflections, and resources that can help teachers and youth workers engage young hearts and minds in reaching out and giving back. Author, and…

In this study I rely on sociocultural views of learning and teaching to describe how fifth- sixth-grade students in a Fostering a Community of Learners (FCL) classroom gradually adopted scientific ideas and language in a socially complex classroom. Students practiced talking science together, using everyday, scientific, and hybrid discourses as…

Memory deficits produced by marijuana arise partly via interaction of the psychoactive component, [Deta][superscript 9]-tetrahydrocannabinol ([Deta][superscript 9]-THC), with cannabinoid receptors in the hippocampus. Although cannabinoids acutely reduce glutamate release and block hippocampal long-term potentiation (LTP), a potential substrate for…

The neural pathways that convey conditioned stimulus (CS) information to the cerebellum during eyeblink conditioning have not been fully delineated. It is well established that pontine mossy fiber inputs to the cerebellum convey CS-related stimulation for different sensory modalities (e.g., auditory, visual, tactile). Less is known about the…

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory…

The purpose of this study was to explore agricultural science teachers' knowledge levels and attitudes toward biotechnology topics. The average agricultural science teacher in this study was a 37-year-old male who had taught for 12 years. He had a bachelor's degree and had lived or worked on a farm or ranch. He had not attended…

In this case study, based on the reported rediscovery of the Ivory-billed Woodpecker in April 2005, students examine a real-world example of the scientific process and explore the practical implications of their conclusions. The case tells the story of Brad Murky, a student and research assistant who must decide whether the available evidence is…

Through associative learning, cues for biologically significant reinforcers such as food may gain access to mental representations of those reinforcers. Here, we used devaluation procedures, behavioral assessment of hedonic taste-reactivity responses, and measurement of immediate-early gene (IEG) expression to show that a cue for food engages…

The German and Australian "longitudinal" surveys analysed here are the first national representative surveys to show that (1) people who continuously own a pet are the healthiest group and (2) people who cease to have a pet or never had one are less healthy. Most previous studies which have claimed that pets confer health benefits were…

This packet contains an Instructor guide and student reference for a course in introduction to grassland management, as well as a crop and grassland plant identification manual. The three-unit curriculum contains the following 11 lessons: (unit I, grasslands and grassland plants): (1) an introduction to grasslands; (2) plant classification; (3)…

The purpose of this cross-age study was to investigate elementary students' (N=120) tacit and explicit understandings of dinosaurs. Detailed analysis of audiotaped interviews of children's performance during a Piagetian-type clinical interview suggests that children's conceptual understandings of dinosaurs are first developed at a tacit level from…

This is the first program in the Science Safari series produced by the Fairfax Network of the Fairfax County Public Schools. The series and the accompanying print materials are designed to show students a broad spectrum of animal life, introduce students to a variety of people who work with animals, and help students become aware of the important…

Some preschool teachers have expressed concern regarding the lack of science instructional material for students age 2 through the preschool years. This videotape was developed to help fill this chasm in our educational system. The videotape provides activities from children's' daily routines, such as eating, playing, and sleeping. It also…
