This module provides a hands-on learning activity where students analyze real-world data to explain how ocean acidification is affecting the oyster aquaculture industry in the Pacific Northwest. Students learn how seawater chemistry affects organisms’ ability to build shells, as well as how short-term variability and long-term changes influence seawater chemistry. The module is designed so that it can be used as an extension to supplement existing ocean acidification teaching resources or as a stand-alone unit for students with no prior exposure to ocean acidification. The module is focused around the question of what is controlling the ability to successfully raise oyster larvae at the Whiskey Creek Hatchery in Netarts Bay, Oregon, which students investigate through guided analysis of real scientific data using Microsoft Excel.
