A short video on the causes of ocean acidification and its effects on marine ecosystems.

In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.

This is an interactive visualization of the Carbon Cycle, through short-term and long-term processes.
