Technical Details
Teaching Tips
- Excellent ocean acidification graphing tool to use in an oceanography/marine biology class. Requires additional information about context, relevance to climate change, and interpretation of data.
- Viewing the visualization in its lesson context http://www.explainingclimatechange.ca/Climate%20Change/Lessons/Lesson%208/lesson8.html would be useful to the educator before using the tool with students.
- The app might best be used in the context of additional information and interpretation.
About the Science
- Visualization is a graphing tool for plotting changes in atmospheric C02 against pH from 1988 to 2009. Data used is adapted from published data, but how it is adapted is not specified.
- Passed initial science review - expert science review pending.
About the Pedagogy
- Visualization is presented with very little background information or context. Data is drawn from one location north of Hawaii; however, the same trends have been observed in other locations around the world.
- Visualization is extracted from Lesson 8, Climate Change and Oceans, in the module Visualizing and Understanding the Science of Climate Change. Lesson 8 can be found at https://cleanet.org/resources/45173.html, or http://www.explainingclimatechange.ca/Climate%20Change/Lessons/Lesson%208/lesson8.html.
