ware tools through shared computer workspaces 

 and two-way audio/video connections. In this 

 project, students and teachers near Chicago 

 (shown on previous page) are woricing on meteo- 

 rology with atmospheric scientists and graduate 

 students in Champaign-Urbana. and will be 

 joined in 1993 by students and teachers in 

 Michigan. Together, they will study the model- 

 ing of unusual weather patterns in their area, uti- 

 lizing real-time weather data from satellites and 

 other sources, such as clouds, temperature and 

 moisture. Any current information on weather, 

 such as the impending conditions giving rise to a 



developing storm, can be accessed using net- 

 works and displayed using local visualization 

 tools, by researchers and students alike. 



Diffusion Limited Aggregation 



Diffusion limited aggregation (DLA) structures 

 arise naturally in fields of science, ranging from 

 electrochemical deposition and dendritic solidifi- 

 cation to various breakdown phenomena such as 

 dielectric breakdown, viscous fingering, chemi- 

 cal dissolution, and the rapid crystallization of 



Color-coded electric field in the vicinity of an electrical conductor molded in tfie shape of a recently discov- 

 ered DLA fractal object. The high school student performing the research was a finalist in the 1993 

 Westinghouse Science Talent Search.
