| Collection Name: | DLESE: Digital Library for Earth System Education
|
|---|
| Collection Description: | DLESE's mission is to improve the quality, quantity, and efficiency of teaching and learning about the Earth System, by developing, managing, and providing access to high-quality educational resources and supporting services through a community-based, distributed digital library. Intended users include students, educators and citizens of all ages, in both formal and informal learning environments. The collection favors resources that convey linkages and connections; the general with the specific, theory with evidence, global with local, and that demonstrate the application of science to solving real world problems. This includes providing access to Earth data sets and imagery, and the tools and interfaces that enable their effective use. DLESE resources are community-contributed, by individuals, organizations, and formal collection efforts. |

| Resource Title: | Snow Crystals
|
|---|
| Description: | This site describes snow crystals and snowflakes. Although a common meteorological phenomenon, snow crystal growth is a fascinating and poorly understood process, in which remarkably complex and beautifully symmetric structures appear, quite literally, out of thin air. The many facets of snow crystals are described here, along with the attempts to understand their formation. Site highlights include research on creating designer snow crystals in the laboratory, the history of early snow crystal observations, snow crystal photography, properties of frozen precipitation, and a snow crystal primer for a short course in snow crystal physics - what snow crystals are, how they form, and why they form the way they do. Information is offered on snow crystal classification, preservation, and unusual crystal forms. An extensive image gallery of lab-created crystal forms is available, with enlargeable thumbnail images. There are even instructions for users on how to create crystals. This could be made into a classroom activity, as the science of the growth is explained. Snowflake Physics discusses diffusion, dendrite growth, ice surface physics, electric growth, and ice properties. A vast list of related links is also provided. |
