Add ocean acidification to your existing lessons

This resource provides an overview of ways to discuss ocean acidification with high school students (14-16 years), including connecting increasing levels of carbon dioxide in the atmosphere with absorption by the oceans and the resulting increase in ocean pH. Topics include understanding pH as a logarithmic scale, the nature of acids (strong vs. weak), and connecting these topics to the U.N. Sustainable Development Goal #14. The article includes links to a student worksheet (with teacher notes and answers) and links to additional resources.
