Described are activities which utilize marine science subjects. These include: assemblage, bas-relief, batik, collage, mobile, montage, paper-mache, and play-dough activities. Includes a list of general suggestions for teachers using aquatic art activities in the classroom. (JN)

Provided is a high school activity in which students observe the filter feeding of barnacles and the effects of a variety of changing parameters upon their feeding process. Includes list of materials needed and procedures necessary to accomplish the activity. (JN)

Describes construction and use of pivots for science equipment and a pin-hole camera (made out of newspaper) for observing solar eclipses. Also describes a method for displaying spectra with a raybox and modification/use of a one-shot submarine (used in floating/sinking activities). (JN)

To make material on Raoult's law more meaningful, students complete exercises on paper, in the laboratory, and with molecular models. Paper exercises give practice using the law; laboratory work illustrates behavior of real solutions; and models show relationships between properties of individual molecules and of matter in bulk. (JN)

Discusses concepts that can be taught using bicycles. Includes examples of activities/experiments using these devices as well as suggestions for their use as research tools for student projects. One area of investigation suggested is an examination of variables that determine the speed at which a bicycle moves. (JN)

Advocates motivating chemistry students while maintaining high academic standards. The curriculum, materials, and motivation techniques used are discussed. The latter includes presenting magic shows to elementary students, decorating rooms, celebrating chemists' birthdays, performing unusual/exciting demonstrations, and others. (JM)

A teaching unit that helps fourth-, fifth-, and sixth-grade students learn about human and animal skeletal systems is described. The unit focuses on bone characteristics and develops basic science skills, such as observation, data collection, and making and testing hypotheses. (PP)

Provides instructional strategies for using fall fruits/vegetables in science lessons, including activities related to melons, pumpkins, grapes, pears, squash, and yams. Suggests extending the activities over a month or more to allow children time to explore and investigate. (JN)

An experiment involving the generation of carbon dioxide gas is used to foster science process skills of observing, recording, and predicting. Student activities related to the experiment are described. (Author/JN)

Describes the Nehru Science Centre in Bombay (India). Includes comments on the cultural/social factors considered during development of and types of activities/exhibits at the center. The activities and exhibits (focusing on all areas of science and technology) were designed to foster experiences with inquiry and problem-solving. (Author/JN)

Examples of the use of hieroglyphics (glyphs) in science and medicine are presented. Suggests having academically talented science students use glyphs to make their own pictorial representations of their own data. (JN)

Lessons on conservation/recycling taught in upper elementary/middle schools often feature a paper recycling activity in which students make new paper from old. Methods to accomplish this are outlined. In addition, the use of the recycled paper for art projects is discussed. (Author/JN)

Assesses student responses to and evaluates effectiveness of exercises designed to develop critical and analytical reasoning skills in the biological sciences. In answering exercises consisting of problems in a multiple-choice format, students are required to write out justifications for acceptance/rejection of each choice. Significant improvement…

Discusses indoor rocketry and use of a vivid model of human birth. Also discusses information (momentum/force) indicating how a motorcycle can be driven up around the increasing slope of an elliptical path, a food testing worksheet, and a worksheet on light for upper elementary/lower middle school students. Includes sample worksheets. (Author/JN)

Describes four body-lever models (biceps, triceps, back lever when lifting, foot lever and Achilles tendon muscle) used in noncalculus physics courses. Instructions for constructing the wooden models are provided. Also describes an improvement on a centripetal-force apparatus so that it is easier to operate. (JN)
