Suggests using Play Doh to mold models of the nucleus, mitochondria, and inner cellular structures. Students can conceptualize the cell's structures as three-dimensional even though they appear two-dimensional under a microscope. Includes instructions for preparing homemade dough. (Author/JN)

Suggests a technique for use in teaching science students how to gather and analyze statistical data. (FL)

Presents a paper that relates human behaviors, such as pleasure, pain, learning, and speech to specific anatomical areas of the brain. (MLH)

Presents six brief questions and answers about human physiology, including the rates of drug metabolism and the mechanism of artifical kidneys. (MLH)

Using pharmacology case studies with nursing students encourages theory-practice links and infuses real-life content. Cases provide rich qualitative data for evaluating curriculum. However, they are not a substitute for evidence-based practice. (SK)

Presents an activity enabling students of grades four to nine to construct a "Buzzing Bee" model using simple materials. Provides students with the opportunity to explore the concepts of sound and the Doppler effect. (MKR)

Nursing students (n=656) used streaming videos on immune, endocrine, and neurological systems using Blackboard software. Of students who viewed all three, 32% found access easy, 59% enjoyed them, and 25% felt very confident in their learning. Results were consistent across three different types and embedding methods. Technical and access problems…

Compares traditional manure application planning techniques calculated to meet agronomic nutrient needs on a field-by-field basis with plans developed using computer-assisted linear programming optimization methods. Linear programming provided the most economical and environmentally sound manure application strategy. (Contains 15 references.) (MDH)

Describes scientific research on an Earthwatch expedition to study Arenal, one of the world's most active volcanoes, in north central Costa Rica. The purpose of the two-week project was to monitor and understand the past and ongoing development of a small, geologically young, highly active stratovolcano in a tropical, high-rainfall environment.…

Nursing education and theory lean toward behavioral sciences, but practice focuses on biomedical problems. Bioscience should be reintroduced to nursing theory through reflective practice. This may also rectify the symbol-object dichotomy in natural sciences, which inhabits the relationship of theory and practice. (SK)

Reviews the biological importance of the lipids categorized as waxes and describes some of the organic chemistry of these compounds. Presents a short laboratory exercise on the extraction of plant waxes and their analysis by thin layer chromatography. (Author/CCM)

Advances six practical suggestions in transpiration whereby teachers can support students in their struggle to put their thoughts, especially everyday mental models, in accordance with classroom experimental evidence. Discusses the wider implications for how to teach about living things and how to view the status of analogies in science generally.…

In a survey of 294 nursing students and 57 faculty, students equally valued lectures, tutorials, and labs for learning biosciences. Faculty differed from students regarding the value of methods and time allocated to the biosciences. Adjustments in the allocation of curriculum topics and a tutorial system to augment lectures and labs were…
