Introduction


We live in a turbulent sea of invisible gases known as the atmosphere.  Our very existence depends on the mixture of gases we inhale and exhale.  Atmospheric gases block, and pass, radiation from space and produce a climate suitable for life. However, atmospheric gases can rapidly circulate harmful substances around the globe.  In this WebQuest, we explore the nature of gases by assuming the roles of design engineers, atmospheric scientists, and aerospace contractors proposing a lighter-than-air craft atmospheric data collection project.  The knowledge gained from such a project is critical for developing better models for predicting weather, improving air transportation, enhancing agriculture, and pursuing alternative energy sources.
