NOAA Ocean Acidification Intro and Classroom Demonstrations

Topics (old): 

NOAA Administrator Dr. Lubchenco presents a 15-minute video about ocean acidification.  She specifically references the effects of ocean acidification on pteropods and corals.  There are two demonstrations featured in this video which would work well in the classroom or with visitors at an aquarium.  One shows the rapid acidification of water when carbon dioxide is introduced.  The other shows how calcium carbonate (in the form of chalk) dissolves in acidic conditions.  This is a good analogy for how ocean acidification will affect animals with calcium carbonate shells.
