Climate Change Ocean Acidification

Did you know that Earth’s oceans are becoming more acidic? Students at Blue Hill Consolidated School in Blue Hill, Maine have been exploring this topic with their science teacher, Nell Herrmann.

To learn about the topic, students were given small coral fragments and asked to conduct a simple experiment demonstrating how acidic solutions affect marine organisms whose tissues contain calcium carbonate. Those animals, such as mollusks, corals, coralline algae, and pteropods, are most vulnerable to ocean acidification.
