Graphing Ocean Acidification

Notes from our reviewers

The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials.

• 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 [link 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 [link http://cleanet.org/resources/45173.html], or [link http://www.explainingclimatechange.ca/Climate%20Change/Lessons/Lesson%208/lesson8.html].
• Technical Details/Ease of Use
  Easy to click the buttons to plot the data and draw a trend line.
