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 activity allows students to demonstrate the thermal expansion of water for themselves using water bottles and straws. The discussion allows them to explore the connection between this concept and sea level rise due to climate change.

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.
