Students study the chemical characteristics of the World Ocean, water chemistry, element cycles, and chemical resources in this multi-media learning module.

In this activity, you can observe how ocean acidification can have big consequences. This activity has students creating a cup that has a carbon dioxide-rich atmosphere that allows them to watch how the water changes beneath the atmosphere.

Understand the ocean acidification problem, and find out what you can do about it.

The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers- the concentration gradient- and illustrates how our oceans are...

[Free Registration/Login may be required to access all resource tools.] This study guide summarizes key points about the composition of ocean water. Includes a few questions to check for understanding.

This site from NASA explains the meaning behind the different colors of the oceans. Gives information as to the role of phytoplankton in the color of the oceans and affects of the carbon cycle on the oceans.

A student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

Investigate the damage that ocean acidification does to the shells of sea creatures.

Students will identify factors that affect the solubility of a salt and test one of the factors (temperature). They will apply their experience to ocean salinity, the effects of temperature on the composition of ocean water, and what...

Get the know the chemical make up of seawater.

Students investigate the effects of salinity on the formation of sea ice, and whether salt water freezes more quickly or more slowly than fresh water.
