Provides innovative ideas in biology, chemistry, and physics on the following topics: enzyme decomposition; chemical waste; time measurement; acid-base color magic; ball bouncing properties; heat; cell theory; and specimen boxes. Materials and procedures are listed when appropriate along with hints for expanding these ideas and investigations. (JM)

Describes the creation and operation of an outdoor laboratory in a city environment for use in teaching environmental education. A map of the laboratory is included. Also describes various stations in the laboratory, presenting a list of materials used as well as several activities based in the laboratory. (JM)

Defends the need for field trips, citing studies that show improved methodology and process knowledge. Also stresses the need for planning to ensure success of such trips and to defend them on a cost basis. Includes two field studies: a north/south slope comparison, and fossil record study. (JM)

Presents background information on seals, legislation designed to protect them, activities related to seals and the fourth International Day of the Seal, and suggestions for field trips. Includes list of materials available from the Seal Rescue Fund with current costs. (JM)

Discusses how school grounds can be used as a resource to relate textbook concepts to everyday life and to understand interrelationships which exist in the outdoors. Possible school ground learnings considered include topics related to weather and weather prediction; changes (aging, growth, decay); geology; temperature; water; and recycling. (BC)

An introduction to and sample activities from a grade two unit on basic needs of wild animals are presented. The unit is part of a curriculum guide developed by the Montpelier Environmental Education Program for grades one to six. (BC)

Discusses the need for preservice elementary teachers to experience inquiry first-hand, suggesting that they engage in problem-solving rather than just "talking about" it. A typical teacher education program is described with suggestions to incorporate inquiry-oriented experiences. An inquiry-oriented activity using sand and funnels is included.…

Offers suggestions for activities in which local weeds and wildflowers are used to study a variety of topics. These topics include classification, ecological succession, and mapping. Also lists the types of experiments students can perform with these plants. (JN)

Describes a versatile electric circuit, a simple and inexpensive vibration generator, and digital electronics demonstrations (with light bulbs) using a microcomputer. Also discusses bimetallic strips and their use as thermostats and the electrical resistance and resistivity of metals. (JN)

Presents (1) suggestions on teaching volume and density in the elementary school; (2) ideas for teaching about floating and sinking; (3) a simple computer program on color addition; and (4) an illustration of Newton's second law of motion. (JN)

Seventh-grade students attended a weekend "camp-out" in which local scientists and college educators were used to enrich students' learning. Information on planning the camp-out and an annotated schedule of events are presented. (JN)

A modified Winkler method for determining dissolved oxygen in water is described. The method does not require use of a burette or starch indicator, is simple and inexpensive and can be used in the field or laboratory. Reagents/apparatus needed and specific procedures are included. (JN)

Described is a science learning center for preschool children, some criteria for selecting materials for the center, and management procedures for the center. (SL)

Described is a method of utilizing meat thermometers to replace bulb thermometers, a chromosome transfer model utilizing colored paper and plastic eggs, a chemical equilibruim experiment utilizing complex ions of Cobalt, and a method of determining the volume of a cylinder. (SL)

Science education is an integral part of scientific endeavors. When the National Aeronautics and Space Administration was created by an act of Congress in 1958, its charter required the agency to "...provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." Part of that…
