Innovating Science® Ocean Acidification Kit

Grades 6–12

Changes to the carbon cycle and climate due to human activities have had detrimental effects on the environment. One example of this is known as ocean acidification, which is the changing of the ocean’s chemistry due to increased carbon dioxide in the atmosphere and ocean. 

In this activity, students will learn about the carbon cycle and how it relates to ocean acidification. Through 3 different activities, students will investigate the cause of ocean acidification and the effects it can have on the ecosystem and marine life. 

Kit contains materials for 15 groups of students. NGSS-aligned teacher’s guide and student study guide copymasters included.
