A set of hands-on laboratory activities that uses the pH scale to understand the changes in ocean chemistry due to increased carbon dioxide emissions. This module shows that increased ocean acidification has adverse effects on marine organisms.
This teaching module will enable students to use the pH scale and visualise changes in the pH of water due to dissolved carbon dioxide. They will observe changes in shells of marine organisms over time when exposed to increased acidic solutions. Students will correlate atmospheric carbon dioxide concentrations and increased ocean acidification.
Use this tool to help students find answers to:
How does an increase in atmospheric carbon dioxide change the pH value of ocean water?
What is the effect of ocean acidification on marine life?
