Learning objectives: By the end of this activity, students will be able to

1. Understand and use different notations for molecules found in water and in air (CO₂, H₂O, etc.).
2. Visualize and interpret chemical equations related to interactions between air and water.
3. Understand the concept of a reversible reaction and know how to represent it using a chemical equation.
4. Understand the concept of dynamic equilibrium.
5. Explain how a change in the concentration of CO₂ in the air affects the dynamic equilibrium of the system.
6. Understand the relation between pH and the concentration of H⁺ ions.
7. Relate ocean pH levels to coral health and the impacts of ocean acidification.
