Session S63a (Wednesday, 9:30am, Wartik 107)

P688: What type of fish will you catch in warm water?

Lauren Thompson (Spring Lake High School, USA)

In this guided inquiry activity, students use a pH indicator to observe how the solubility of carbon dioxide gas in water changes with temperature. Students contrast these results with what they know about the effect of temperature on solubility of solids. Additionally students use these results to determine how the temperature of the water affects what type of fish are found in waters of different temperatures and how thermal pollution from industrial sites might affect fish. A description of the experiment, tips for facilitation of this activity, student results, and teacher reflections will be presented.
