Describes a project making a model of the celestial sphere that will show how the ancients imagined the universe. (PR)

Summarizes plenary papers presented at the NSF/SSMA Wingspread Conference to explore ways to improve science and mathematics education through integration. Themes included analysis of integration; divergence of mathematics education from science education; technological perspectives; promoting mathematical and scientific inquiry; and school…

Describes career opportunities in Clinical Laboratory Science formerly know as Medical Technology. Explains classroom strategies for brining these careers to the attention of students. (PR)

Describes science experiments with the enzyme lactose, which is available commercially as Lactaid and Dairy Ease. Experiments show how the rate of reaction of lactose converted to glucose and galactose is influenced by temperature, pH, and substrate concentration. (PR)

Presents a study of four different teaching strategies dealing with comparing lower-level questions with higher-level questions and comparing feedback correctives with no feedback correctives. The lowest levels of achievement were in the class with low-level questions and no feedback correctives. (PR)

Notes that traditional early childhood science programs have attempted to facilitate children's understanding of the physical or natural world. Suggests another view: that children are developing scientific thinking processes or learning strategies in the personal and social domains, and that this should be seen as part of science program in early…

Presents an activity that allows students to experience the type of discovery process that paleontologists necessarily followed during the early dinosaur explorations. Students are read parts of a story taken from the "American Journal of Science" and interpret the evidence leading to the discovery of Triceratops and Stegosaurus. (PR)

Presents activities to familiarize junior high school students with the processes behind and reasons for volcanism, which is generally a planet's way of releasing excessive internal heat and pressure. Students participate in the creation of four important volcano-related simulations: a lava flow, a shield volcano, a cinder-cone volcano, and a…

Presents three patterns found in math for elementary students. Spirolaterals are patterns made by repeatedly tracing a series of three numbers in four directions on dot paper. Tessellating can be a combination of teaching about patterns, geometry, and art. The King's Problem requires recognition of a problem to find a solution. (PR)

Describes the rebuilding of a Project Physics fan cart on a PASCO dynamics cart chassis for achieving greatly reduced frictional forces. Suggests four experiments for the rebuilt cart: (1) acceleration on a level track, (2) initial negative velocity, (3) different masses and different forces, and (4) inclines. (MVL)

Describes a method for determining the distance to the horizon which leads to determining the radius of the Earth. The article answers two interesting science questions: (1) Can you see the state of Kansas from Pike's Peak in Colorado? and (2) Can you see two sunsets in one day on the Keys of Florida? (MVL)

Researchers revised a psychological assessment of organization in memory to measure organization in thinking. Secondary students viewed a videotape, wrote essays, then created word trees using provided words that eliminated the memory component in their original task. The ordered-tree technique reliably measured organization in thinking.…

Reviews "Thematic Units: An Integrated Approach to Teaching Science and Social Studies" (Fredericks, Meinbach, and Rothlein); "Using Poetry across the Curriculum: A Whole Language Approach" (Chatton); "Getting Down to Cases: Learning to Teach with Case Studies" (Wassermann); "Phonic Phacts" (Goodman); and "English As a Second Language: 25…

Illustrates developmentally appropriate physics activities for young children. Addresses ways that teachers can use the environment to teach physics and answers the questions: What is the value of physics for young children? What are criteria for developmentally appropriate physics activities? How does one integrate physics into a project or unit…

Describes a wave of reforms set in motion by Nobel laureate Leo Esaki, to encourage industry to play a bigger role in graduate education through a new program that enables doctoral candidates to work in 31 participating corporate and government labs near the University of Tsukuba, Japan. (LZ)
