Examines the working mechanism of a commercial "Mystery Glow-Ball" by analyzing its electronic circuitry. Finds that the advertising for the ball is wrong; energy actually came from inserting a battery. (YP)

Describes the use of a biology guidebook which contains a course outline, syllabus, reading list, handouts, and sample tests all bound together in booklet form for better organization and teacher effectiveness. (RT)

Described is the manufacture of a superconductor from a commercially available kit using equipment usually available in schools or easily obtainable. The construction is described in detail including equipment, materials, safety procedures, tolerances, and manufacture. (Author/CW)

Describes this year's chemistry exhibition held in Japan and sponsored by the Chemical Society of Japan. Summarizes the purposes, preparation, and the activities of the exhibition. (YP)

Proposes a simple procedure based on an expansion of the exponential terms of Raoult's law by applying it to the case of the benzene-toluene mixture. The results with experimental values are presented as a table. (YP)

Described is the subject of biological scaling for physics teachers including examples and in-depth reading. Topics are elements of scaling, terminal velocities, Lilliputian and Brobdingnagian, brain evolution, dolphin echolocation, surface tension, gravity change, food and oxygen, and seeing. Ten references on physics and size, and ten questions…

Describes ways to use nomographs, including solving equations for equivalent resistance of a parallel circuit, focal length of a thin lens, parallel combinations of standard resistance, average speed, refraction problem, and height of a vertically projected object. (YP)

Presents an annotated bibliography of 48 outstanding children's science books. Entries are grouped under six headings. The appropriate age range is noted for each book. (BB)

Presents instructions to build a device that helps students see the effects of the ultraviolet radiation around them. Suggests ways to utilize the device. (MDH)

Micropipetting is an important skill that plays a very active and critical role in the molecular biology laboratory. It is imperative for a person handling micropipettor to know the correct way of using it so that accurate and precise results are achieved.

Each publication in the Eisenhower National Clearinghouse (ENC) Focus series presents a small selection of the Clearinghouse collection focused on a topic of particular interest to mathematics and science teachers. In addition to meeting general requirements for inclusion in the ENC collection, curriculum materials in the Focus series are:…

This book is written for people who tend to sit toward the back of the classroom during scientific lectures. It assumes that students remember nothing of what happened in their science classes. The book is divided into seven sections: (1) Magnetism; (2) Bending Light Waves; (3) Bacterial Stories; (4) Light Wave Craziness; (5) Homemade Science; (6)…

The Eisenhower National Clearinghouse for Mathematics and Science Education (ENC) helps teachers by offering a broad assortment of services that enable them to quickly locate educational resources. This document is one in a series of print catalogs designed to give educators information about curriculum resources available for teaching math and…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this interpretation produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…
