A differential scanning calorimeter was used to study homogeneous nucleation of ice from micron-sized aqueous ammonium sulfate aerosol particles. It is important to understand the conditions at which these particles nucleate ice because of their connection to cirrus cloud formation. Additionally, the concept of freezing point depression, a topic…

A wind vane is a tool for making observations of wind direction and initiating inquiries about the weather. Its construction and use continue to be mainstays of the science education of elementary students. By providing students with the opportunity to discern critical features associated with the wind vane's operation, you can ensure that…

Now available as a Download! This valuable resource helps educators teach students about both the risks and benefits of flooding through a series of engaging, hands-on activities. Acknowledging the different roles that floods play in both natural and urban communities, the book helps young people gain a global understanding of this common--and…

Describes how the study of a hurricane can be used to provide integrated basic mechanics in a first-year college course in engineering mechanics. Presents models that predict wind speed given surface eye pressure and several radial dimensions of the storm and calculate total kinetic energy once the wind speed is determined. (ZWH)

The term weather is commonly used to refer to the condition of the atmosphere as it affects people's activities on the earth's surface. Four weather elements are considered in this unit: clouds, precipitation, temperature, and wind. This publication details the materials, objectives, supplemental materials, background information for the eight…

Provides (1) background information on global winds, air masses, fronts, and pressure systems; (2) five activities on this topic; and (3) a ready-to-copy coloring page and worksheet. Each activity includes an objective, list of materials needed, recommended age level(s), subject area(s), and instructional strategies. (JN)

Discusses the history of weather forecasting from the Babylonians to today's computers and provides information on snow, hail, sleet, fog, winds, clouds, and fronts. Includes possible student outcomes and a student quiz. (JOW)

Provided are 26 ideas to help children explore the effects of mountains on the weather. Weather conditions in Nepal and Colorado are considered separately. Nine additional sources of information are listed. (CW)

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature,…

This syllabus is divided into three sections and three appendices. The first section lists program objectives with corresponding performance criteria for seven areas of weather/climate study: (1) broad-scale weather systems; (2) local weather; (3) the atmospheric environment; (4) energy and motion in the atmosphere; (5) water in the atmosphere;…

Introduces Wilson A. Bentley, who studied precipitation. Discusses Bentley's method for measuring the number, size, and shape of raindrops and determining the rate of rainfall. Lists required materials and explains the procedure for students and teachers. Provides scientific background on condensation and precipitation. (YDS)

The task of providing hands-on as well as minds-on activities for students in science is one of concern to many scientists and educators. In an effort to inspire student interest in science and technology, scientists from the Forecast Systems Laboratory, a laboratory within the National Oceanic and Atmospheric Administration's (NOAA) Environmental…

Water Cycle is one of the units of a K-6 unified science curriculum program. The unit consists of four organizing sub-themes: (1) atmosphere (highlighting the processes of evaporation, condensation, convection, wind movement and air pollution); (2) water (examining the properties of liquids, water distribution, use, and quality, and the water…

Background information using Hurricane Gilbert (1988) is provided. Ideas for 27 activities including a mapping activity are discussed. The 5 themes of geography are listed and a glossary is given. (CW)

Presented are 35 activities that center around television and newspaper weather reports. Geography, weather, and other disciplines are included as well as various grade levels. Available resource materials are listed and their uses explained. Parent, administrator, and other faculty member involvement is emphasized. (KR)
