The purpose of this paper is to present five new devices that demonstrate a variety of flow phenomena in liquids and granular materials that exhibit fluid-like behavior. These devices complement and add on to a recent collection of demonstrations that was published in this journal. The devices are self-contained and portable, and can be utilized…

A look at a program established to assist teachers in repairing and maintaining science equipment. A Science Instrument Repair Center has been set up at the northern branch of the Delaware Technical and Community College. (Author)

A construction of a simple gas apparatus that can be made by students either in the laboratory or the classroom, is presented. The components needed to construct the apparatus are disposable polythene pipets and polypropene microcentrifuge tubes.

Explains the principle upon which a barometer operates. Describes how to construct two barometric devices for use in the classroom that show air's changing pressure. Cites some conditions for predicting weather. (RT)

Through the use of science-reading kits, one teacher develops practical application of children's reading skills. Each child designs and builds appropriate materials for science learning kit on the subject of his/her choice. (SA)

Described is a multidisciplinary group project for undergraduate students in astronomy and physics. The students design and build a simple radiotelescope subject to a number of realistic constraints such as fixed cost, use of a standard communications receiver, and buying of supplementary building materials off the shelf.

Science curricula typically do not capitalize on the hands-on, self-initiated learning style of young children. This book provides a comprehensive, developmentally appropriate approach to science education with young children, with special attention to physics and chemistry. The book's introductory chapter is followed by chapters on: (1) science…

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)

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

Describes an extra credit science project in which students compete to see who can build the most efficient water rocket out of a two-liter pop bottle. Provides instructions on how to build a demonstration rocket and launching pad. (MDH)
