Explains that the use of data on CD-ROMs gives undergraduate students an economical way to work with real data on potentially publishable projects. Describes a student project using the data on the World WeatherDisc to find evidence of Indian Summer in Spokane, WA. (PR)

Presents a simple activity designed to allow students to experimentally verify Kepler's second law, sometimes called the law of equal areas. It states that areas swept out by a planet as it orbits the Sun are equal for equal time intervals. (PR)

Presents follow-up activities to learning scientific concepts that utilize concepts from books obtained from the school library. Suggests seven books and related science activities involving shadows, force, animals, nature, dinosaurs, machines, and mirror reflections. (Contains 10 references.) (MDH)

Describes a class activity where individual students ask the teacher "yes and no" questions to find the amount of force the bicep uses to lift a 1 kilogram mass. (PR)

Inservice workshop trained fourth- and fifth-grade science specialists and their students organized science demonstrations presented by students from each grade level. Describes demonstrations involving liquid bubbles, magnets, measurement, sound, aerodynamics, environmental protection, and air pollution. (MDH)

Describes the following uses for a video camera in the science classroom: video presentations, microscope work, taping and/or monitoring experiments, analyzing everyday phenomena, lesson enhancement, field trip alternative, and classroom management. (PR)

Describes a plastic soda bottle water rocket launching system used in a first-grade class. Encourages teachers to introduce the concept of rockets with two books, "Trouble in Space" (Rose Greydanus) and "Space" (James Seevers). (PR)

Three hands-on science activities teach students about plant processes that they normally cannot detect. A K-3 activity has students explore how the presence of water affects plant motion. Two grade 4-6 activities let students see the path water takes through leaves and has students investigate how and why water travels through plants. (SM)

Explains the work of a primary-research group focusing on the practical aspects of the use of scale in science. Reports on three studies that look at the impact of the representation of scale in different areas related to the Standard Assessment Tasks (SAT). (DDR)

Focuses on the use of a science-based topic with children ages six and seven to explore ideas for developing children's use of descriptive language. Employs talk partners and circle time as strategies for developing language. (DDR)

Discusses the mathematics and science underlying Eratosthenes' measurement of the circumference of Earth in about 200 B.C. and provides a lesson plan so that small groups of high school students can duplicate the measurements. Equipment needed and related Web sites are listed, and a model chart to record measurements is provided. (PEN)

Describes one teacher's experience taking Space Discovery courses that were sponsored by the United States Space Foundation (USSF). These courses examine the history of space science, theory of orbits and rocketry, the effects of living in outer space on humans, and space weather. (DDR)

Details the use of a grant to enhance science education and the science curriculum through a series of workshops and a resource program. Describes the development of interdisciplinary units. (DDR)

Presents an unconventional assessment in the form of a card game for use in evaluating student understanding of severe weather-related concepts. Discusses the theory behind using educational games for instruction and assessment. (DDR)

Investigates how the design, creation, and revision of animated models that tell a science story can assist young bilingual children in science learning. Findings show that the animated software provided students with access to a world that is normally unavailable in real time; they were also able to manipulate science concepts and connect…
