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?

Classroom/Laboratory Activity: Survival Skills—Response of Organisms to Climate Change

A classroom/laboratory activity to analyze the distribution of beetle, mammal, and plant species (for datasets from North America) in the past (based on fossil records), determine whether the same species exist today, and compare the past and present geographic ranges and ecosystems of these species.
