Provides background information on poison ivy and offers suggestions for instructional activities. Includes illustrations of the varieties of poison ivy leaf forms and poison ivy look-alikes. Highlights interesting facts and cases associated with poison ivy and its relatives. (ML)

Presents an account of the making of a wildlife garden. Reviews the problems and outlines the plans and methods that succeeded in the project. Includes 21 illustrations of vegetation as well as descriptions of pond, marsh, meadow, and woodland areas. (ML)

Three innovative ideas for college instruction include a freshman assignment to write recruitment letters to high school students with similar interests, introductory art history classes taught solely in a museum adjacent to the campus, and use of the "Hunt of the Unicorn" tapestry to combine plant identification practice with art…

Describes the analysis of dandelion peduncle growth based on peduncle length, epidermal cell dimensions, and fresh/dry mass. Methods are simple and require no special apparatus or materials. Suggests that limited practical work in this area may contribute to students' lack of knowledge on plant growth. (Author/DH)

Currently, there is much research work investigating the teaching and learning of plant nutrition in several different countries. This article briefly summarizes the findings of some of this work, including the work undertaken by the Children's Learning in Science Project. (Author)

Presents biology, chemistry, physics, and health activities, experiments, demonstrations, and computer programs. Includes mechanism of stomatal opening, using aquatic plants to help demonstrate chemical buffering, microbial activity/contamination in milk samples, computer computation of fitness scores, reservoir project, complexes of transition…

Describes a unit on seeds designed to introduce students to their scientific and nutritional uses. Unit activities are easily done, employ a variety of process skills, and can be used at various grade levels. Suggests field trips to gather seeds, seed sprouting, and making cookies out of various whole grains. (JM)

This paper describes a study conducted on the lab sections of the general biology course for non-science majors at the University of New England, and reports findings of student misconceptions about photosynthesis and the mass/carbon uptake during plant growth. The current study placed high technology analytic tools in the hands of introductory…

Intended for use in elementary and high school education, this Web site includes a teacher's guide and three lesson plans. The site contains images of museum specimens, scientific drawings, and field photos of the plant and animal species observed by Meriwether Lewis and William Clark, along with journal excerpts, historical notes, and references…

Offers suggestions for teaching some aspects of water economy in plants. These include diffusion/osmosis, water transport, the part played by turgor in structural support, and its implications for plant organs or whole plants. Several practical demonstrations/experiments are also described. (JN)

Discusses the earth's biosphere, considering how the microbial, animal and plant life (which make up the biosphere) are sustained by the earth's lithosphere, hydrosphere, and atmosphere. Also considers how these three earth features have powerfully shaped the evolution of these organisms. (JN)

Some simple field investigations on plant water relations are described which demonstrate links between physiological and external environmental factors. In this way, a more complex picture of a plant and how it functions within its habitat and the effects the environment has on it can be built up. (Author/JN)

Provides procedures for growing from spores to demonstrate alternation of generations, life history, and morphology of pteridophytes. (CS)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

Try to learn all you can about a plant in the winter. As the season changes, you can see what the dried seed pod is like in bloom. You are a convert if you notice a spectacular show of summer wildflowers and wonder what sort of winter weed will result. (Author/CM)
