Describes a series of activities and demonstrations involving the science of soap bubbles. Starts with a recipe for bubble solution and gives instructions for several activities on topics such as density, interference colors, optics, static electricity, and galaxy formation. Contains some background information to help explain some of the effects.…

Described is the separation of dyes using a conventional liquid chromatographic pump and a glass column. Included are the preparation of the column and dye separations. (CW)

Describes the construction and uses of a low cost fermenter reaction vessel which is suitable for laboratory growth of microorganisms by continuous and batch cultures from plastic soft drink bottles. Lists materials, discusses modifications that can be made and gives examples of use. (CW)

Describes experiments designed to measure the oxygen content in the atmosphere and related areas in the high school laboratories. Considers the application of these activities to other programs. Includes a description of the binuclear complex and recommended procedures. (CW)

Describes an experiment for undergraduate chemistry laboratories involving a chemical found in plants and some sea animals. Discusses collection and identification of material, a hemolysis test, preparation of blood-coated agar plates, and application of samples. (CW)

Discusses some of the ways that rocks can be used to enhance children's creativity and their interest in science. Suggests the creation of a dramatic production involving rocks. Includes basic information on sedimentary, igneous, and metamorphic rocks. (TW)

Describes a study in which elementary school children received different types of instruction about terminology used in explaining the water cycle. Results indicated that the group of students receiving hands-on instruction demonstrated a better understanding of the terms than did the other groups involved in the study. (TW)

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)

Provides 12 ideas for bulletin boards that can be used to teach basic skills while at the same time help students understand more about animals. Describes the activities that can be done with each bulletin board, along with a list of materials and instruction. (TW)

Describes several chemistry demonstrations that use an overhead projector. Some of the demonstrations deal with electrochemistry, and another deals with the reactions of nonvolatile immiscible liquid in water. (TW)

Provides a listing of 35 demonstrations designed to generate interest in organic chemistry and help put points across. Topics include opening lecture; molecular structure and properties; halogenation; nucleophilic substitution, alkenes and dienes, stereochemistry, spectroscopy, alcohols and phenols, aldehydes and ketones; carboxylic acids, amines,…

Describes a game in which students deal with some of the factors involved in being a responsible pet owner. Includes a list of the materials needed for the game and provides the game board and the game pieces, along with a fold-out poster about neutering and spaying pets. (TW)

Presents a new, high-technology approach to making bulbs light in series and parallel circuits. Contains diagrams that illustrate the circuit patterns. Provides suggestions for applying the electronic principles that were addressed in the activities. (ML)

Demonstrates how Piaget's theoretical framework of a preschool science curriculum, with illustrative experiences using paints, sound, and food, can help teachers develop their ability to provide appropriate science experiences in their classroom. The framework can also help teachers evaluate the activities suggested in literature. (BB)

Discusses the advantages of basing computer simulations on analogues of nature rather than mathematical models. Explains the concept of heritability and describes how a computer simulation can help undergraduate students understand this concept. (ML)
