Describes how books damaged during fire fighting operations are frozen to prevent mildew, then dried in a thermal vacuum chamber and restored to usable condition. (Author/EA)

Water resources play a major role in the character of agricultural development in the arid western United States. This case study shows how thermal infrared imagery, which is sensitive to radiant or heat energy, can be used to interpret crop moisture content and associated stress in irrigated areas. (RM)

Provided in this teaching package are materials that clearly and simply unveil the mysteries of water pollution. Materials, written on an approximate seventh-grade level, include: (1) a student reading unit; (2) water quality factors pamphlet; (3) experiments; and (4) teacher's guide to field testing a local waterway. The student reading unit is…

A "healthy and high performance school" uses a holistic design process to promote the health and comfort of children and school employees, as well as conserve resources. Children may spend over eight hours a day at school with little, if any, legal protection from environmental hazards. Schools are generally not well-maintained; asthma is a…

This study investigates the relative effects of thermal applications of varying temperatures on the flexibility of specified joints. Subjects were 14 male college students ranging in age from 17 to 22 years with no previous joint injury or orthopedic disability. Each subject became familiar with the experimental design and was asked not to engage…

Ideas for elementary school teachers are proposed. Demonstration experiments include thermal conductivity of gases, wetting power of detergents, external pressure effects on boiling point of water, frequency-wavelength relations, density of hot and cold water. Other useful tips are given for protecting wall charts and making descriptive labels.…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical pressurized water reactor (PWR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating its use with a simplified model. The heart of the module is the PWR…

The thermal gravimetric analysis (TGA) data suggests that the quantity of volatile components in primary standards is less than 1% of the initial weight and differential scanning calorimetry (DSC) data shows that water present in the same chemicals is below the limit of detection of the instrumentation. This suggests that the 1-2 hour drying…

Provided are procedures for a demonstration which illustrates the concept of summer stratification of lakes in the temperate zone as maintained by thermal resistance to mixing. The demonstration requires only food coloring, water, and common laboratory equipment. (JN)

An experiment that consists of following the changes in temperature at different depths in a precooled liquid while the liquid slowly warms up to the temperature of the surrounding environment is presented. The experiment might be used in a course on temperature, on heat transmission, and in particular in the study of convection currents.

Basic concepts of waste heat management on shallow and deep small water bodies and rivers are reviewed and examples are given. This study defines a small water body as a body in which the far field hydrothermal effects of a heated discharge can be detected in a major portion or practically all of the water body. Environmental effects due to…

The Standard's purpose is to provide design requirements that will improve energy utilization in new State of Alaska owned rural educational facilities ranging in size from 7,000 to 12,000 square feet. The Standard covers exterior envelopes and selection of heating, ventilating and air conditioning systems, service water systems, energy…

Presents three experiments that provide examples of how plants modify their surroundings and create microenvironments. Examples demonstrate (1) how types of ground cover influence water quality; (2) how plants can create a thermal microenvironment; and (3) how plants can serve as barriers to wind. (MDH)

Attempts an explanation of how "ice spikes" are formed. The spikes are upward protrusions of ice that occur when water expands as it cools in a rigid container of low thermal conductivity. Describes the results of an investigation and includes color photos. (LZ)

Ten units which focus on subject-matter knowledge about energy and on the logic and strategy of problem-solving within science are provided in this user's guide. Each unit includes: a detailed summary of unit problems and activities; recommended grade levels and subject areas; possible learner outcomes and general goals; teacher background…
