Summary: The project was designed to show how sound traveled through different substances and then equate this to how sonar causes damage to whales underwater. Various chemicals in liquid, solid and gas phases were compared to each other at the same temperature and to themselves at different temperatures. The chemicals were chosen on the basies of their chemical formula, structure, atomic mass, and amount of differing amount of valence electrons. These results were then used to show how and why aquatic life (specifically whales) are more affected by sound in water than those creatures that are above ground.

Problem of the Propagation Lab:
What does a molecule’s structure and properties (temperature, etc.) have to do with its acoustic properties?

Purpose of the Transmission Lab:
To determine the radius of direct damage due to resonance caused by the Low Frequency Active Sonar (LFAS)used by the US Navy.

Hypothesis:
We believe there is a direct correlation between LFA Sonar use and the beaching of whales. We also believe that not only is a whale's communication disturbed but they are physically affected by these sounds.
