A science laboratory was developed for use by kindergarten through sixth-grade students. The operation of and the types of science activities used in this laboratory are described. (JN)

This book provides opportunities for engaging students in scientific investigations, offering a hands-on approach that encourages students to understand science concepts, gives them ways to apply the concepts, and introduces and reinforces the skills they need to become independent investigators. The basic outline and objectives of each section of…

The Nevada Science Standards represent a common core for curriculum throughout Nevada's schools. The Nevada Science Standards are intended to provide Nevada students with a rich, thorough, and varied science education to prepare them for the challenges, discoveries, and demands of life in the 21st century. The two main sections of the document…

This teacher's guide complements five programs that aired on the Public Broadcasting System (PBS) in the fall of 1999. Programs include: (1) "Fall of the Leaning Tower"; (2) "Everest: The Mystery of Mallory and Irvine"; (3) "Time Travel, Decoding Nazi Secrets"; (3) "Voyage of Doom"; and (5) "Barely…

Characteristics of the archaebacteria (comprising the methanogenic, thermoacidophilic, and extreme halophilic bacteria) are discussed, including comparisons of molecular traits for archaebacteria, eubacteria, eukaryotes, and taxonomic considerations. Issues related to integrating the archaebacteria into biology curricula and teaching about the…

A set of instructions for growing algae successfully in the classroom and maintaining the culture is provided. Aids for identification of freshwater organisms are suggested. (SA)

Through course management and careful measurement of student performance, and through appropriate use of media and microprocessors in instruction, more effective courses can be developed. (Author/MK)

Presents a practical problem to students in a junior-level thermodynamics course in which a human body regulates its own internal temperature. This problem can be utilized as well (with modification) in an introductory physics course for life science majors. (HM)

Describes the collection, care, and maintenance of protozoa by elementary school students. Techniques for collecting and observing them are given. (SA)

A model is described for preparing graduate students to teach undergraduate biology courses. Features of the program include instruction in using innovative techniques, the use of pre- and in-service components, and the use of experienced biology teaching assistants. (Author/SA)

Physiology programs must continue to prepare graduate students for research postdoctoral positions. They should also prepare them for employment at smaller institutions that have higher teaching demands and that encourage-but do not require-research. Suggests changes in the way Ph.D. candidates are taught and in the way professors mentor students…

Discusses strategies for teachers to get back in touch with the earth and re-connect with the environment. Argues that the teacher's appreciation for nature's beauty will bring about a sensitivity not experienced before and help students develop a reverence and awe for the natural world. (JRH)

A procedure for extracting DNA from yeast using common reagents and equipment is given. Suggestions for variations are provided. A second activity for building a model of DNA from toothpicks is included. (CW)

Reports on some potential teaching problems associated with children's scientific ideas about the concept of mutation. Provides information on the sample, methodology of study, and analysis. Concludes that in biology teaching the treatment of the concept must ensure that its genetic sense is specifically delineated. (RT)

The porphyrias are a family of genetic disorders whose genetics and biochemistry are largely identified. Background information on these diseases are discussed including porphyrins, gene expression, population genetics, and historical significance. (CW)
