Curated OER
Water Density and Salinity
Middle schoolers 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...
Curated OER
What's A Water Column Profile?
Students investigate water column data. In this earth science and seawater lesson, students determine how temperature, salinity, and density have an impact on sea water by viewing and analyzing data obtained from a number of websites....
Curated OER
Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties instructional activity, students read a background activity for the instructional activity and experiments to the topics. Students...
Curated OER
Estuarine Currents
Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
Curated OER
Ocean Microstructure
Students assess the ocean's microstructure by analyzing graphs created during tne Ronald H.Brown research cruise. they discuss at what depths various sea animals live and write paragraphs on data analysis from the graphs.
Curated OER
The Future of Arctic Sea Ice
Students research about the importance of sea ice to world climate and sea organisms. In this earth science lesson, students create a model of present and future Arctic sea ice communities. They discuss how ice melting affects...
