Lists the advantages of having insects as classroom animals and suggests lessons utilizing them for science, English, social studies and mathematics. (LS)

Presents the inside story of how an elementary school science curriculum incorporated into its program the building of a greenhouse, built at very low cost due to student and community enthusiasm. Materials and palns are described. (EB)

First of a series showing ways in which the preschool setting can provide exploratory activities for the young child seeking to become acquainted with the world about him. Suggests ways to present the concepts of climate, clean air, personal space, and noise level. (EB)

The evolution of a laboratory oriented undergraduate plasma physics course is described. Brief accounts of the 14 experiments utilized in the course are provided. (CP)

Describes experiments, demonstrations, activities and ideas relating to various fields of chemistry to be used in chemistry courses of secondary schools. Three experiments concerning differential thermal analysis are among these notes presented. (HM)

Describes the construction of an apparatus to demonstrate the tilting of an oil-water, gas-water, or gas-oil interface when the subsurface reservoir is under hydrodynamic conditions (i.e., when conditions of lateral flow exist). The model can be constructed of readily-available materials. (RE)

Basic principles of physical hydrogeology and the nature of hydrologic interactions between groundwater and surface water can be demonstrated using two devices, the miniature piezometer and the seepage meter which can be cheaply constructed by the teacher and students. Use of the devices and learning activities are presented. (RE)

This inexpensive, effective chemiluminescence demonstration requires minimal preparation. It is based on the oxidation of oxalyl chloride by hydrogen peroxide in the presence of an appropriate fluorescent sensitizer. The reaction mechanism is not completely understood. (BB)

Using aerial photographs to study shrubs biomass allows students to avoid unpleasant working conditions and to study communities that are inaccessible or distant. (BB)

Describes how involving the students' bodies in the study of certain scientific principles, such as center of gravity, pendulums, and volume by water displacement have resulted in building up their interest and increased their motivation toward learning science. (GA)

This article suggests the use of the circuit box to illustrate the processes involved in the scientific method. Construction and wiring diagrams and a materials list are presented. (BB)

Presents a calorimetric experiment designed to clarify some of the basic physics of heat transfer and insulation. (GA)

Describes a simple inexpensive experiment designed to measure the levels of cortisol in a serum or plasma sample. (Author/GA)

Describes the college level experiments: a simple measurement of the isotopic abundance of 40-K, a mechanical experiment, on kinetic energy, and on soap films between wedged plates. (GA)
