This facilitator's guide, and the videotape it accompanies, is designed to demonstrate ways in which the new visions of science education for the 21st century might be translated into classroom practice. The National Research Council's (NRC) National Science Education Standards, American Association for the Advancement of Science (AAAS) Benchmarks for Science Literacy, and other frameworks were used as guides in developing this series. The videotape presents views of real classrooms where science is being taught. Classroom situations are spontaneous and unscripted. The videotape shows how standards actually look in practice in the classroom and how teachers are guiding experiences that enable students to construct understanding and learn science processes. The guide contains information on conducting hands-on workshops including materials lists, materials sources, and handouts. The videotape focuses on the primary grades. In the first lesson, kindergarten students learn about land snails in an integrated unit that includes literature, drawing, and making models from clay and paper. In another unit, children learn about predator-prey relationships and how the structure of each living thing adapts to survive in its habitat. Finally, second grade students use prediction, number concepts, and graphing skills in their observation of the heaping property of water. (PVD)
