Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)

Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)

Examines the effect of solar radiation on colored shingles. Describes the experimental procedure, results, and discussion. Presents a picture of the experimental arrangement and three graphs of data measured at different dates. (YP)

Presents a lesson on introducing writing into the science curriculum by using an experiment to illustrate the detrimental effect of tobacco smoke on human lungs. Outlines the materials, procedures, a summary of the project, extension activities, and additional information about the writing process. Two handout sheets are included. (RT)

Describes the National Sea Grant Program and eight types of education programs. Examines funding patterns from 1976 through 1987. Assesses current status of education within the Program using a director's survey. Discusses some implications for science educators.

Presents year-long, elementary science projects that address the question of why daylight hours vary in length according to locality. Provides three instructional units designed to commence in September, including data collection activities for sunny days encouraging later classroom calculations; on-going graphing activities; and modeling…

Describes an approach to introductory geology that requires students to go into the field to make observations, collect and analyze data, synthesize those data, and hypothesize about inferred geologic relationships. The product of these laboratories is a paper that requires students to test their hypothesis using specific examples from the data.…

Examines participation in science competitions to determine (1) whether gender differences in participation exist, and (2) whether there are gender differences in the subject areas selected (biological versus physical sciences). North Carolina student participation data were used for the years 1987-88. Gender differences in science competitions…

Describes a project where students were involved in finding the most suitable site for a landfill in their community. This two-month project was conducted using team teaching. Two twelfth grade geoscience classes were involved. (PR)

Provides instructions for making telescopes. The design and instruction sheets given to students are provided. (PR)

Describes a contest where sixth-grade students observe the results of a week of planning, folding, testing, and comparing their best paper frog designs and hopping techniques. This integrated unit helps children unleash their imaginations and develop problem-solving skills. (PR)

Presents a water-quality monitoring project in a Denver school that has evolved into an experiment using a constructed wetland system to treat the acid-mine drainage from an abandoned gold mine. (PVD)

Reports on a case study that examines the beginnings of gender differentiation during a naturally occurring academic activity designed to support and guide young children's interest in doing science. Contains 25 references. (DDR)

Presents an alternative to the competition fostered through traditional science fairs. The Science Expo is an all-day event meant to show students and the community that science is fascinating and fun. (PR)
