- Additional classroom implementation activity set up to go along with video http://www.amnh.org/content/download/41766/606631/file/classroom_acidoceans.pdf.
- Easily used in any unit dealing with oceans, marine biology, and climate change.
- Link to VirtualSeaUrchin Ocean Acidification Lab to carry out the experiment on line: http://virtualurchin.stanford.edu/teachers.html
About the Science
- The ocean has absorbed about a third of the carbon dioxide emitted through human activities, altering the pH of the ocean, reducing its buffering.
- Through the University of California, Santa Barbara, sea urchins are used to set up ocean acidification experiments testing how CO2 affects sea urchins' formation of their calcified parts like spines, exoskeleton and mouth parts.
- Comments from expert scientist: excellent discussion of real studies of the effects of ocean acidification on development of larval urchins. I would use it in any high school or college class.
About the Pedagogy
- Background text provided and links to discussion questions provided.
- Glossary and Additional classroom implementation activity set up to go along with video are available with links and additional background.
