Reading: The climate in our hands – Ocean and Cryosphere

The Office for Climate Education (OCE) presents a Teachers Guidebook that aims to support teachers in carrying out various activities on climate change and the ocean and cryosphere in their classrooms, and targets students of ages 9 to 15. 

Teaching Module: pH Scale, Ocean Chemistry and Impact of Ocean Acidification on Marine Life

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.

Classroom/Laboratory Activity: Ocean Chemistry, Ocean Acidification, and Oyster Growth

A classroom/laboratory activity to learn about the pH of ocean water, explore the potential effects of climate change on ocean acidification, and understand the possible impacts of ocean acidification on marine organisms such as oysters.

Students will explore and analyze the relationship between the growth of oyster larvae and the chemistry of ocean water (aragonite saturation state) by plotting graphs for actual data from the Whiskey Creek Hatchery in Oregon, USA.

Use this tool to help your students find answers to:

  1. If ocean water became more acidic, how might it affect oyster populations?
  2. What are the possible impacts of climate change on the chemistry of seawater?
