Dickinson College (Pennsylvania) has a new sports center featuring a clear span roof system and an "earth sink" that stores excess heat for later use. The relationship between sports and the liberal arts is the basis for courses taught in the center. (Author/MLF)

At the Telluride (Colorado) school, the classroom wing was outfitted with a thick floor slab and a greenhouse space where heat is stored in waterfilled tubes. The gymnasium's southwestern wall was transformed into a Trombe wall by applying 2,000 square feet of glazing. (Author/MLF)

The sun makes its own terms, and they must be acknowledged. The response to these terms is apparent in sections of solar buildings used for high-density development or homes. (Author/MLF)

Designed to help teachers deal with students in a cold environment, this article explains cold physiology and fundamental laws of heat; describes 14 common cold injuries and their current treatment; and lists a number of useful teaching techniques for cold environments. (SB)

A heat reclaim system and careful insulating will cut energy use in a University of North Carolina, Chapel Hill, medical laboratory-office building. (Author/MLF)

Describes an experiment in which chemistry students determine the efficiency of a laboratory burner used to heat water. The reaction is assumed to be the complete combustion of methane, CH4. The experiment is appropriate for secondary school chemistry students familiar with heats of reaction and simple calorimetry. Contains pre-laboratory and…

Thermochromism is the reversible change of color of a solid when heated or cooled. Describes the preparation of thermochromic compounds that exhibit sharp thermochromic transitions. (DKM)

Explores early railroad expansion and ways in which new railroad technologies contributed to the development of the United States, particularly the western states. Activities help students understand how steam engines work, why stopping trains can be a lengthy proposition, why magnets will figure prominently into future trains, and why train…

A closed-loop geothermal heating system in a Minnesota school uses the earth's temperature as a counterweight to the extremes of temperature on the surface and in the school. The system is expected to recoup its extra investment in fewer than five years of service. Cites statistics concerning energy management in schools. (MLF)

The ninth installment of the Science in a Box series (self-contained, hands-on activities for students grades three and up) presents activities for learning to use the sense of touch to determine how different objects conduct heat. All projects in the series are inexpensive and easy to assemble. (SM)

Analyzes students' misunderstanding of basic thermodynamic concepts on historical grounds. Finds that the persistence of some ideas from the caloric model are reinforced by magnitude names and unit definitions that were brought up at the early stages of thermodynamic development. Explores the failure of many popular textbooks to make a clear…

On equilibrium properties of aqueous solutions of sulfuric acid, Julius Thomsen has marked that the heat evolved on diluting liquid sulfuric acid with water is a continuous function of the water used, and excluded absolutely the acceptance of definite hydrates as existing in the solution. Information about thermochemical measurement, a discussion…

The potency of heat in gases is measured by the application of a computer and the LabWorks interaction, while the speed of sound in gases is determined by an instrument called Kundt's tube. This unique and accurate procedure is repeatable, and greatly reduces data acquisition time.

Having students design and construct solar cookers is a great way to teach them about designing to meet human needs and about many basic global issues related to health and the environment. Because the activity includes solid content from the fields of math, science and technology, it is an excellent vehicle for technology educators who want to…
