The solubility of gases in water is controlled by several principles. In this lesson you read about the various principles and explore the principles through computer animation. After the computer animations you use WOW data to find evidence of supersaturation and develop an understanding of the physical basis for oxygen supersaturation.

Knowledge Base
Complete the WOW reading on the chemistry of oxygen solubility. Your teacher will work through the related computer animations, Heny's Law and Induced dipoles.

Experimental Design
You need to find evidence of O₂ supersaturation. What clues in a lake that might indicate that O₂ supersaturation is occurring? Write an experimental plan detailing the data and methods you plan to use to confirm O₂ supersaturation.

Data Collection
What data do you plan to collect? What do expect to see in your data? How do you plan to organize the data? Collect the WOW data you identified.

Data Management and Analysis
Create graphs and/or tables using the data you collected. Label your axes and legends and title your graphs and tables. Can you confirm supersaturation from the data? How?

Interpretation of Results
Consider what additional data might indicate supersaturation? Would looking at other lakes verify your results or pose a new experimental question? Would looking at different dates verify your results or pose a new experimental question?

Reporting Results
Use the data and your reflections to create a presentation. The presentation can be a written report, poster, oral presentation, or multi-media presentation. Be prepared to answer any question about your experimental plan or your data.
