This sourcebook provides science investigations for junior high students. These investigation are coordinated with the seven integrating conceptual schemes formulated in 1964 under the auspices of National Science Teachers Association. The investigations were developed, classroom tested, and contributed by classroom teachers. (RS)

Five pamphlets offer helpful ideas and instructions on teacher planning, learning environments, teaching with nature, a creative curriculum, and ideas for administrators in "The Idea Box," compiled by members of the Austin Association for the Education of Young Children. Each pamphlet contains useful information for working with young children.…

Presented is a curriculum guide for preschool programs serving both handicapped and nonhandicapped children. It is explained that the guide is intended to suggest classroom activities which will strengthen existing skills and encourage development of new skills. The guide presents information on objectives, materials and procedures for the…

Discusses the properties of carbon dioxide in its solid "dry ice" stage. Suggests several demonstrations and experiments that use dry ice to illustrate Avogadro's Law, Boyle's Law, Kinetic-Molecular Theory, and the effects of dry ice in basic solution, in limewater, and in acetone. (TW)

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)

Describes a microcomputer program that can be used in teaching the basic physiological aspects of acid-base (AB) balance. Explains how its game format and graphic approach can be applied in diagnostic and therapeutic exercises. (ML)

Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Describes a chemistry experiment where an alkaline ice-cold permanganate solution is reduced by adding dropwise a cold diluted hydrogen peroxide solution. Outlines the course of the reduction through the various oxidation states of manganese with their characteristic colors. (TW)

Outlines an approach to chemistry experiments designed to help students appreciate the importance of each step in an experimental procedure. Describes an experiment involving Charles's Law to illustrate this idea. (TW)

Describes a program for sixth grade students developed by the Methacton School District (Norristown, PA) Planetarium staff. Provides brief outlines of eight teaching units designed to provide students with hands-on activities in astronomy. Includes a reproducible worksheet for an activity which involves students in creating and decoding…

Provides background information on how scientists have learned about the history of the Earth, including studying fossils, dating rocks, and tracing geological movements. Included are teaching activities about prehistoric animals, state fossils, tracing animal movement and evolution, and discovering fossils. Contains reproducible handouts and…

Provides background information on the many natural resources we extract from the earth's crust, including metals, graphite, and other minerals, as well as fossil fuels. Contains teaching activities such as a geologic scavenger hunt, a geology chronology, and the recycling of aluminum. Includes a reproducible handout for the activity on aluminum.…

Suggests how simple hikes can be integrated into the elementary school curriculum. Presents nine topic areas that can serve as themes for schoolyard hikes. (ML)

Indicates the inadequacies and limitations of traditionally written elementary science textbooks. Offers suggestions and provides examples for teaching more accurately and experientially the nature and process of science. Identifies several sources for enrichment of the textbook. (ML)

Differentiates between problems, exercises and algorithms. Discusses the role of algorithms in solving problems and exercises in chemistry. Suggests that very real differences exist between solving problems and exercises, and that problem solving steps can be and should be taught in chemistry education. (TW)
