The manufacture of metal alloys is ubiquitous, yet infrequently discussed in high school coursework as concepts related to them are often too complex or abstract for beginning science students. However, earlier introduction to metallurgy in classroom settings could promote interest in practical applications of chemistry, physics, and geology due…

Learning how cave formations, such as dripstone, take shape can be a valuable pedagogical tool in chemistry and geochemistry. Grasping the underlying processes requires students to synthesize knowledge of several different topical areas. The activity presented here uses an innovative experiment to connect chemistry concepts with an interesting…

Describes a simple activity designed to show the effects of leaching and evaporation on salts in the soil. (CP)

This is the second in a series of guidebooks written for elementary school teachers to help improve their science teaching. The book emphasizes processes of science and creativity as well as science content. The book is divided into three sections--the atmosphere, the lithosphere, and the hydrosphere. Each chapter begins with simple concepts, and…

Describes an introductory course in geology for nonscience majors that involves students in laboratory exercises related to rock classification. (GS)

Describes activities by which the porosity and permeability of materials with respect to water can be measured. (CP)

Describes a geology laboratory exercise involving weathering and topographic maps which allows students to put knowledge to practical application. (SL)

Designed for use in Pennsylvania secondary school science classes, this guide is intended to provide fundamental information in each of the various disciplines of the earth sciences. Some of the material contained in the guide is intended as background material for teachers. Five units are presented: The Earth, The Oceans, The Space Environment,…

This publication is one of a series of single-topic problem modules designed for use in undergraduate geology and earth science courses. The first section, "Ain't It Flat? A Series of Experiments in Geodesy," presents various experiments for determining the earth's circumference (historically) and describes the use of satellites in determining the…

Describes a demonstration experiment illustrating rotation of grains process of metamorphic rock formation utilizing clear gelatin blocks. (SL)
