NOVA video (4:07), is Ocean After a short description of how carbon “What Acidity?”: dioxide dissolved in ocean water changes chemistry, this excellent video uses structural water’s formulas of the molecules and ions to show the series of five reactions given in the Hale article and explains that the carbonate ion is the limiting reagent required to form calcium carbonate shells for aquatic life. () Lessons and lesson plans of Acidification on Coral class periods): This multi-section “Effect Reefs” (two-50-minute lesson plan produced by Gustavus/Howard Hughes Medical Institute Outreach Program includes readings, a hands-on lab with pre-lab, student questions, and a video. See a list of links at the end for additional resources. () Inquiry lesson—why do we explore? (two 45-minute class periods): a “Ocean Health”, lesson based on exploration and research from the NOAA ship Okeanos, asks, factors “What tend to resist changes in ocean Students seek answers during a hands-on laboratory pH?” activity; the site contains thorough answers to questions and lab preparations that include how to make artificial sea water, with supplementary links provided for the teacher. () Projects and Extension Activities Research project on This investigation, from Carleton College, MN, “Ocean Acidification”: of other carbon dioxide involves the study of the long-term effects of carbon “the problem” dioxide acidification on aquatic animals. Suggested materials include articles, discussion questions, videos, and a virtual (data based) lab exercise on sea urchins. () an Amplifying Greenhouse This site provides an evaluation “Slowing Down Effect” project: and risk/benefit study of technologies designed to reduce atmospheric carbon dioxide. The project includes student research, articles to read, a NOVA video, and questions to address. () References The Guide for the April 2009 ChemMatters article on algal blooms contains Teacher’s some interesting information about the adverse effect of ocean acidity on the ability of clownfish larvae to locate coral reefs through “tasting” (smelling). ________________________
