This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

This simulation allows students to explore the change in sea surface pH levels with increasing CO2 levels.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.

This series of two lessons uses cutting-edge scientific research on the effects of climate change on communities in the intertidal. Through a combination of a dynamic presentation and several videos, students are introduced to the effects of climate change on the ocean (ocean acidification and temperature increase) and what is known about how ocean organisms are affected. Then students read and interpret graphs and construct a scientific explanation based on data from this research.
