About the Science
- Student groups conduct a set of acid-base experiments to see what could happen to the pH of the ocean as carbon dioxide levels rise in the atmosphere.
- While these experiments do not show how carbon dioxide is dissolved into the ocean, they do demonstrate the relevant chemistry.
About the Pedagogy
- Student worksheet at http://oceanservice.noaa.gov/education/pd/climate/teachingclimate/acid_base_chemistry_student.pdf
- The experiments in this resource show how acid-base chemistry is relevant to understanding how excess carbon dioxide in the atmosphere contributes to the acidification of the ocean and its impact on corals and humans.
Technical Details/Ease of Use
- Links to key article (In Hot Water...) and other resources listed in the student and teacher guides do not work as of 11/2016. Some resources may need to be supplemented with others.
- The "In Hot Water" article referred to in the activity is available here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2453177/
- Both the Student's and Teacher's Guides are well done. They are well organized and provide appropriate background materials for students and guidance for teachers.
