Description
Students first observe the effect that atmospheric carbon dioxide has on the pH of simulated seawater. Next, they investigate the effect that temperature has on the solubility of carbon dioxide in seawater by heating samples of acidified and non-acidified simulated seawater and observing changes in pH. Finally, students measure the change in mass of crushed coral placed in an acidified solution for 5 days, to examine how calcium carbonate structures are affected by increasing ocean acidity.
- Connected to Unit 9: Global Change, topic 9.7: Ocean Acidification
In this series of laboratory activities, students investigate ocean acidification. First, they observe the effect that atmospheric carbon dioxide has on the pH of simulated seawater when it is absorbed. Next, students investigate the effect that temperature has on the solubility of carbon dioxide in seawater by heating samples of acidified and non-acidified simulated seawater and observing changes in pH as an indicator of changes in dissolved carbon dioxide. Finally, students measure the change in mass of crushed coral placed in an acidified solution for 5 days, to examine how calcium carbonate structures are affected by increasing ocean acidity.
