Examined 297 students in biology classes where girls are encouraged in science, focusing on actual science experiences, masculine/feminine tasks, extracurricular science activities, feelings about science classes, research funding, and science career interest. Suggests that equal experiences within science classrooms do not overcome advantages…

Examined ability levels, attitudes, expectations, and affective outcomes of junior high students (N=147) who voluntarily enrolled in extracurricular science activities at Weizmann Institute of Science (Israel). Results indicate that for high ability students there is a need for theoretical and experimental independent study which can be found in…

Presents two activities on acid rain for students in intermediate grades. Materials needed and procedures used are included. Also describes "chemical magic" shows performed by high school students for sixth-grade students in seven elementary schools in Altus, Oklahoma. (JN)

A laboratory exercise allowing students to use drillhole data to simulate the process of locating a placer gold paystreak is presented. As part of the activity students arithmetically compute the value of their gold, mining costs, and personal profits or losses, and decide on development plans for the claim. (BC)

Suggests ways to teach science while young children are actively involved in art, construction, reading, and music. These suggestions are listed for learning centers which focus on art, blocks, homemaking/dramatics, water/sand, manipulatives, language, outdoors, and music. Also indicates that "moments" for teaching science occur in many places…

Describes (in separate articles): computer simulations in science education; how junior high school students revised an experiment; a framework for assessment in science; physics, relevance, and understanding; a science module for a sixth form general studies course; and assessment of providing science education for the 16-19 age group. (JN)

Reports findings of a study on children's perceptions and alternate conceptions about the human circulatory system. Summarizes the responses of fifth and eighth grade students on questions dealing with the heart and blood. Offers examples of hands-on activities and confrontation strategies that address common misconceptions on circulation. (ML)

Contains teaching activities designed to help elementary students understand the meaning of "endangered" and to recognize the major causes of species loss throughout the world. Organizes the exercises by grade levels and also by time required for the activity's completion. The major concepts and skills of each lesson are identified. (ML)

Describes an archaeology program identified by the National Science Teachers Association's Search for Excellence in Science Education project as an outstanding science program. Program objectives (including attention to research detail, interpretation, deduction, and interrelationships of different disciplines) and student activities are…

Stereology is the study of three-dimensional objects through the interpretation of two-dimensional images. Stereological techniques used in introductory botany to quantitatively examine changes in leaf anatomy in response to different environments are discussed. (JN)

Discusses the use of the Bank Street Laboratory sound probe in activities focusing on various aspects of sound. Also examines what students were learning during the activities (such as students understanding what is meant by the pitch of a tone). (JN)

Discusses how the concept of crystallography, especially the relationship between spherical and stereographic projections of crystals, is more easily understood by undergraduate students if they make spherical projections of crystals. Recommends using transparent balloons and a felt-tipped marker to denote the locations of crystal axes, face…

Describes a procedure for starting tree cuttings from woody plants, explaining "lag time," recommending materials, and giving step-by-step instructions for rooting and planting. Points out species which are likely candidates for cuttings and provides tips for teachers for developing a unit. (JM)

Describes the use of a 35-millimeter camera with color slide film to produce photographs of constellations, star trails, bright comets, aurorae, and meteor showers. Discusses film speed, lenses, f-stop settings, exposure times, and other items related to astrophotographic technique; provides ideas for use of slides in the classroom. (JM)

Provides examples of science activities in which children use their senses in manipulating objects and ideas. Suggests that these and other activities be extended to help children deepen their understanding of scientific concepts. (JN)
