Describes an experiment based on Faraday's one-piece generator, where the rotating disk is replaced by a cylindrical permanent magnet. Explains the apparent paradox that an observer in an inertial frame could measure his absolute velocity. (GA)

Presents sixteen project notes developed by pupils of Chipping Norton School and Bristol Grammar School, in the United Kingdom. These Projects include eight biology A-level projects and eight Chemistry A-level projects. (HM)

Describes a multi-project pack on central heating systems, developed into an educational game, used for teaching a variety of subjects in high school. The students examine the basic decision to install a central heating system, for a particular house, and the economics involved. (GA)

Describes activities that demonstrate the effects of factors such as wind velocity, water temperature, convection currents, intensity of light, rate of photosynthesis, atmospheric pressure, humidity, numbers of decomposers, presence of oxidizable ions, and respiration by plants and animals on the dissolved oxygen concentration in water. (MA)

Describes an electroplating experiment which utilizes photovoltaic (solar) cells to drive the chemical reaction. (SL)

Describes ways in which: (1) paintings, (2) crayon rubbings, and (3) clay modeling can be used to demonstrate science concepts. (CP)

A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)

Examines a free choice program and ways seventh graders choose their own activities in five science categories: (1) Mechanical; (2) Physics; (3) Chemistry; (4) Biology, and (5) Combinational. Results suggest that the challenge format for the activities allows students to practice what they have learned and consolidate their knowledge. (HM)

Described is a mouse cage that can be built, at a cost of about $15, by intermediate-aged elementary students. (BB)

This article describes a summer Field Astronomy course designed to give secondary students the opportunity to use the telescope as a laboratory instrument, to learn telescope optics, and to do experiments related to observation. The equipment is described and illustrated. (Author/MA)

A possible use of toy gliders to introduce elementary school children to flight and to sharpen their skills of observation is given. (MR)

The construction of a measurement device to determine elevation is described. Activities for use with the device for upper elementary and secondary students are included. (CP)

Provides a number of articles reviewing the use of the TV program Star Trek as a motivation for educational programs, and describes the Star Trek Educational Programs (STEP) program. (SL)

Describes science-related competitive events in which 10th and 11th grade students participated. The organization and operation of the olympiad is detailed. (CP)

Describes a final year undergraduate course in which students use X-ray diffraction to identify clay minerals. (SL)
