Discussed is the possibility that the salmon found in the Columbia River (Idaho) is an endangered species. A list of threatened or endangered animal species in the Pacific Northwest is included. Activities that deal with the topics of diversity, endangered species, and what is being done about them are provided. (KR)

Presents the experience of a Canadian Science-Technology-Society (STS) curriculum project as an indication of the problems that likely follow from attempts to introduce a STS curriculum piecemeal. These problems include redundancy within school curriculum and reduced time for science concept and term acceptability of the STS proposals. (PR)

Reports a study (n=27) concerning the knowledge about image formation exhibited by students following instruction in geometrical optics in an activity-based college physics course for prospective elementary teachers. Student diagrams and verbal comments indicate their knowledge can be described as an intermediate state: a hybridization of…

This theme unit includes elementary-level language arts, math, science, art, and critical-thinking activities about gardening. A full-color poetry mini-poster and an idea for growing a special Mother's Day tea are also included. Students learn about different types of gardens as they grow their own plants, and develop a vocabulary of flower names.…

Describes creative methods of teaching elementary level science: eighth-grade hands-on experiments are made with rare rocks and gems via a "Mining by Mail" program; third-grade students use the "I Wonder" approach to examine questions of interest; process skills are adapted for different age levels. A staff development folder…

Provides five fully developed library media activities that are designed for use with specific curriculum units in reading and language arts, science, and social studies. Library skills, objectives, grade levels, instructional roles, procedures, evaluation, and follow-up are described for each activity. Topics include poetry, memory, plant/animal…

This study explored preservice teachers' (n = 25) knowledge structures and their mastery of content knowledge in relation to their ability to diagnose the strengths and weaknesses of a fourth grader's videotaped explanations of a scientific phenomenon, i.e., molecular kinetic properties of air. Participants' knowledge structures were analyzed…

The Experimental Reflection Portal, or "XRePort" is an online system that pairs students and teachers from different schools and allows them to "talk" about their common science investigations. In this way, students communicate their science knowledge "and" experience firsthand the benefits of the collaborative nature…

This study examined preservice teachers' understanding of, and processes when, designing instruction. Participants were 47 juniors and seniors enrolled in science methods courses. Qualitative methods and analysis of written reflections and interviews revealed the beliefs and views the preservice teachers had about planning. Findings are as…

The study explores urban second graders' thinking and talking about the concepts of evaporation, boiling, and condensation that emerged in the context of intertextuality within an integrated science-literacy unit on the topic of States of Matter, which emphasized the water cycle. In that unit, children and teacher engaged in a variety of…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

This science curriculum was written for teachers of children in junior high or middle school. It contains science activities for the following lessons: (1) Anemometers and Wind Speed; (2) Up! Up! and Away; (3) Jet Lag--Time Zones; (4) Inventors; (5) Model Rocketry; (6) Geometry and Kites; and (7) Super Savers. In lesson one, students construct an…

This concept paper outlines the rationale for a project on the development of science curriculum for K-8 high ability learners. The rationale was developed through a synthesis of major recommendations from national science reform reports and from a review of the literature on effective science curriculum for high ability learners. The paper begins…

"Talking Science" does not mean simply talking about science; it means doing science through the medium of language. This is a book about communication, scientific, and technical education. Chapters 1 and 2 introduce the specific themes and methods of the book. Each analyzes a brief classroom episode, looking from two different points of view at…

Nationally many middle-level schools are changing from a traditional junior high school structure (grades 7-9) to middle schools (grades 6-8). A case study examined the impact of middle school organizational changes that occurred as a large North Carolina school system converted from junior high schools to middle schools on science teachers and…
