This book is a collection of 28 experiments that are not meant to have any practical purpose. Each experiment, however, illustrates a scientific principle and enables students to discover how scientific facts and theories apply to seemingly useless experiments. Each experiment includes a list of materials, a series of steps, an explanation of the…

This is the fourth program in the Science Safari series produced by the Fairfax Network of the Fairfax County (Virginia) Public Schools. It focuses on large animals, their life, advantages and disadvantages of their size, and the adaptations that allow them to survive in their environments. The large animals highlighted include the Komodo dragon,…

This Solar System Puzzle Kit for grades 5-8, allows students to create an eight-cube paper puzzle of the solar system and may be duplicated for classroom use or used as a take home activity for children and parents.

Each issue presents factual material about the planet, diagramatic representations of its movements and positions relative to bright stars or the earth, actual photographs and/or tables of data collected relevant to Pioneer 10, the spacecraft…

The relationship of the mechanics of a falling chimney and a breaking pencil point is presented. A device is discussed that uses a pocket calculator coupled to a telescope to record the angle at which the telescope is pointed. (BB)

A special tear-out-and-duplicate section provides activities for increasing environmental awareness. (RW)

As an alternative guide to science teaching, a generalized theory of scientific observation defined in terms of human intentions and purposes is offered. The generalized theory, while based on assumptions different from those of the science education theory, can still account for the plausibility of many aspects of that theory. (JN)
