Students research and create a visual presentation on the seasonal salinity of the Earth's oceans. They apply the research in a simulation of a lab disaster in which they must relabel ocean samples.

Young scholars observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the...

A pool of brine in the deep sea can be up to four times as salty as the surrounding sea water. The deep sea ecosystem relies on chemosynthesis and the organisms that live there are often strange to us. The lesson focuses on researching...

Students take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.
