Ocean Layers I
How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...
Curated OER
Water Density and Salinity
Students 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 density...

Ocean Layers II
Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...
PBS
Sea Surface Temperature, Salinity, and Density
Earth's vast ocean is full of mysteries! Science scholars discover the big-picture properties that influence its characteristics at different latitudes using a lesson from PBS's Weather and Climate series. After completing a background...

What Lives in the Open Ocean and Where Do They Live?
Students explore oceanography by participating in a flash card activity. In this ocean inhabitant lesson, students define a list of ocean related vocabulary terms and answer ocean geography study questions. Students utilize organism...
Curated OER
Properties of the Ocean: Change
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.
Curated OER
The Open Ocean, What is it and How Does it Change?
Students investigate the ocean environment. In this ocean lesson, students discover the physical properties of the ocean. Over two days, students work in small groups investigating ocean maps and creating water currents.

One World Ocean
Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...
Polar Trec
Sea Ice Impact
The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...
