In this laboratory investigation, student teams discover that the ocean's capacity to dissolve carbon dioxide depends on its temperature, and consider the effect of a warming ocean on CO² absorption. The activity requires Bromothymol blue indicator solution (BTB), Alka Seltzer tablets, household ammonia, a heat source, and laboratory glassware. The investigation is supported by the textbook, Climate Change, which is part of Global System Science, an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.
