Describes two types of star charts commonly available for astronomical viewing and outlines a strategy by which teachers can have students use a computer spreadsheet to prepare their own easy-to-use star charts appropriate for the location, date, and time of viewing. (Author/MKR)

Reviews the rationale for integration of mathematics, science, and environmental education. Provides 12 references and an annotated bibliography of 25 teaching activities and ideas for use in primary and secondary education which can be found in the ERIC database. (LZ)

Describes an approach of two elementary school teachers in combining instruction in reading and science. Students brainstorm a list of things they know about a topic; then they generate a list of things they wish to find out. Students read and conduct science activities to find out what they wish to know. Then students summarize what was learned.…

Describes activities with organisms from freshwater ponds and ditches. Several experiments involve predation, some involve habitat choices, and one addressees the role of sunlight in supporting plant-eating animals. (PR)

Describes a drama where students play the parts of NASA employees in charge of planning a space mission to one of the planets. (PR)

Presents a Project WET water education activity. Students demonstrate how everyone contributes to the pollution of a river as it flows through a watershed and recognize that everyone's "contribution" can be reduced. Student distinguish between point- and nonpoint-source pollution. (LZ)

Scientific reasoning of four elementary age students with mild mental retardation was investigated using structured interviews during tasks involving properties of air and electricity. Discourse analysis was employed to describe students' preconceptions about the natural world and how those preconceptions might be influenced by empirical evidence.…

Suggests a way of teaching science to young children that is consistent with Piaget's interpretation of the child's spontaneous animism and that elicits a personal and in-depth response to knowledge. Describes construction and use of an environmental bubble to enhance children's interest in the night sky. (SW)

Presents a sample exercise developed for use in a student-driven classroom as part of a first-year, one-semester course, "Mechanisms of Biology." The approach places each student in an active role as questioner and as an intrinsic part of the course structure itself. The exercise is given on the first day of the course as a primer. (LZ)

A review of introductory college level and high school biology texts reveals that concepts and theories behind classification are usually poorly discussed. Suggests ways in which card games can be used to teach differences between the phenetic and phylogenetic approaches. (LZ)

Reviews the DynaPulse 200M Education Edition microcomputer-based laboratory, which combines interactive software with curriculum and medical instrumentation to teach students about the cardiovascular system. (MKR)

Emphasizes two aspects for a calculus-based physics course: applying calculus and numerical integral methods to determine the theoretical period of a pendulum with nonlinear motion, and achieving theoretical and experimental results by using "MathCad" software and a microcomputer-based laboratory (MBL) system. (MVL)

Presents topography activities. Includes a chart of topographic mapping symbols. (MKR)

Provides simple techniques for demonstrating and recording the effect of the changing shapes of moving objects when viewed through a moving slot. Includes a puzzle. A computer shareware program (IBM compatible) that simulates the distortions is available from the author. (MVL)

Describes the use of constructivism in teaching human anatomy. Provides directions for constructing arm-hand and leg-foot models that include extensor and flexor muscles and that are easily and cheaply constructed. Lists resources that provide ideas for using such models depending upon the curriculum implemented in a school or the course that is…
