Discusses current biological research related to plants, including rootless plants, cellulose synthesis, plant identification in forensic science, and plant chemistry. Contains 19 references. (WRM)

Discusses the educational and political aftermath of the 1968 Epperson v. Arkansas ruling that laws banning the teaching of evolution were unconstitutional, and made it unconstitutional to ban the instruction of one theory and not the other. Reviews past and present court rulings as well as the role of creationists in the United States. (CCM)

Evaluates a thematic program designed for use in introductory biology courses. Main objectives include the following: to provide relevancy of biological concepts beyond the classroom, be process oriented, integrate units within a biology course, teach for higher-order thinking, and expand the use of resources beyond the textbook. (CCM)

Identifies seven guideposts for tropical rain forest education. Aids teachers in finding structure and creating educational experiences that promote more complete understanding of tropical rain forests. (CCM)

Offers a simple experiment that tests the effectiveness of cleaners that inhibit bacterial growth. Outlines a step-by-step method for preparing culture media that can be used for isolation and propagation of microorganisms. Concludes that kitchen medium is as efficient as the professionally-made medium in supporting colony growth. (CCM)

Presents a directed-inquiry activity to take students one step beyond observation of how living organisms capture prey. Uses a field lab based upon predator-prey relationships to enliven the teaching of food web concepts to non-science-major freshman undergraduates. Can also be used in teaching high school biology students through college science…

Introduces activities to reinforce the concept of and problems involved with introduced, nonnative or alien species. Provides seven vignettes about seven different plant and animal species that have become or currently are near ecological disasters. (CCM)

Introduces the freshwater oligochaete worm, lumbriculus variegatus (common name: blackworms), an organism that is well suited for classroom study because of its closed circulatory system. Describes a set of simple, fast, noninvasive, and inexpensive methods for observing pulsations of the worm's dorsal blood vessels under baseline conditions, and…

Presents an activity that stresses the role of fungi and decomposers, highlights the rapidity by which they complete this process, and allows students to experiment with ways to control the rate of decomposition. (CCM)

Presents a fun, inexpensive, and pedagogically useful laboratory exercise that involves indoor studies of the dispersal properties of the winged fruits (samaras) of boxelder trees. Engages students in the process of hypothesis testing, experimental design, and data analysis as well as introducing students to important concepts related to…

Presents a game called the Meiosis Shuffle that helps students simulate the process of meiosis in which homologous cards representing chromosomes pair up, line up, and split apart. Students respond well to the simulation and are better able to conceptualize what chromosomes do and how independent assortment causes genetic variation. (CCM)

Argues that biologists' understanding of the cell has become richer over the past 30 years. Describes how genetic engineering and sophisticated computer technology have provided an increased knowledge of genes, gene products, components of cells, and the structure and function of proteins. (CCM)

Describes the background and outcome of the McLean v. Arkansas Board of Education case heard in federal court in the early 1980s. The decision repealed a legislative act which called for "equal time" in science classrooms for presenting evolution and creationism. The decision also established that "creation science" had no scientific merit or…

There are significant variances in both the religious and non-religious beliefs for rejecting evolution, and likewise diversity in the extent to which various creationists reject evolution. Describes the anti-evolution stances of literalists, progressives, and theists and addresses teaching concerns relative to anti-evolution positions. Contains…

Describes six books appropriate for use with high school advanced or honors biology classes. The stories describe scientists who persevered against existing preconceptions in science or society at three levels: (1) prevailing mainstream scientific ideas; (2) gender; and (3) nationality or race. Presents ideas for using biographies as part of a…
