Designing against Disaster
Civil and structural engineers face a challenging task when designing buildings and other infrastructure. They have to account for a multitude of safety issues related to fire, floods, and natural disasters. That challenge is twofold with the additional risk of terrorism, because blast protection could be a major concern for high-profile structures.California's Golden Gate Bridge is in the process of being retrofitted for enhanced seismic stability.

Ozone depletion interactive lab
What is the process by which CFCs destroy ozone? This informational piece, part of an interactive laboratory series for grades 8-12, explores the destruction of the ozone layer by chlorofluorocarbons. Here students view a four-step animation that shows how ultraviolet light breaks chlorine free from a CFC molecule. The chlorine then destroys an ozone molecule. Additional steps show how the process can be continuous. Copyright 2005 Eisenhower National Clearinghouse
