Introduces a range of simple ideas about soil physical properties using a minimum of apparatus. (MKR)

Reports on the successful classroom use of commercial fertilizers as growth media. (ZWH)

Describes a conceptual model for integrating short scientific texts, which extends classical text storage and retrieval. A brief comparison with related approaches such as case-based reasoning and classification-based reasoning is also provided. (13 references) (Author/KRN)

Discussion of informational books for young people focuses on a study of authors of children's science books. Data are reported from authors in the United States, Canada, and Great Britain in four main areas: (1) background in education and experience; (2) science-related hobbies and interests; (3) research techniques; and (4) reasons for writing.…

Compliance with International Standardization Organization (ISO) standards for the presentation of periodical publications was evaluated in 221 Spanish biomedical journals to determine the degree to which the standards are actually used, and to develop recommendations for improving standards and increasing familiarity with them among authors,…

Reports findings of an Indirect-Collective Referencing (ICR) investigation carried out in a representative sample of the elite physics journal literature, "The Physical Review," in the January 1997 issues of 44 source journals. Findings revealed ICR phenomenon present in all journals, that the quantity of non-indexed ICRs in this literature…

Children love nonfiction books, and their reading of such texts has shown a strong relationship between science achievement and informational reading and writing abilities. How can elementary teachers capitalize on this natural affinity and make the most effective use of nonfiction trade books in their classroom? There are numerous strategies to…

When a commercial pilot steps into the cockpit of an airplane, it has been serviced by a host of personnel and will be supported by many more from takeoff to landing. In more and more places, when an elementary school teacher steps into inquiry-centered science instruction, his or her materials have been carefully prepared by a team of experts,…

Each publication in the Eisenhower National Clearinghouse (ENC) Focus series presents a small selection of the Clearinghous collection focused on a topic of particular interest to mathematics and science teachers. In addition to meeting general requirements for inclusion in the ENC collection, curriculum materials in these publications are…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this interpretation produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…

Provides an analytical solution of a model representing the collision of an atom with a harmonic oscillator, interacting via a repulsive square well potential. Presents results for various energies and strengths of inelastic scattering. (Author/CP)
