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.
Complete the WOW reading on the chemistry of oxygen
teacher will work through the related computer animations, Heny's
Law and Induced dipoles.
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
you plan to use to confirm O2 supersaturation.
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.
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?
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?
Use the data and your reflections to create a presentation.
The presentation can be a written report, poster, oral presentation,
presentation. Be prepared to answer any question about your experimental
plan or your data.
