Live Investigation - Coral in a high CO2 world (AM)

This session illustrates how the increase in carbon dioxide in the ocean is lowering pH levels, thus impacting marine life. The first activity Ocean acidification in a cup shows how water becomes more acidic when carbon dioxide is bubbled through it. The second activity Dissolving ‘coral’ and ‘shells’ in vinegar explains how acidic substances can ‘dissolve’ coral reefs and shells which protect ocean life.

Part of: Coral Live 2018
