Water Quality
Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples. Students then compare their measurements with others in their class as well as other standard measurements.

Ocean Microstructure Lesson Plan
Students explore the microstructure of the ocean by analyzing graphs created by Dr. Mike Gregg of the University of Washington Applied Physics Laboratory during the EPIC 2001 research cruise on the Ronald H. Brown NOAA vessel.

Desalination: Creating a Solar Still
To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Learning Lesson: That Sinking Feeling
Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.
Curated OER
Estuarine Currents
Learners experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine 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
We All Scream for Ice Cream
Students make ice cream while experimenting with the freezing point of water. They experiment with different amounts of salt.
Curated OER
Investigating Convection Currents
Pupils examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.
Curated OER
What is an Estuary?
Students define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.
Curated OER
A Salty Experiment
Students study salty and fresh waters. In this harbor estuary lesson plan students complete a lab activity on salinity and describe what happened.

Conductivity - Pass the Buoy and Pepper, Please
Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface...

Do You See What Icy?
Here is a lesson that kicks off with a question. "How does ice floating on the ocean act as it melts?" As learners investigate this natural phenomenon, they'll discover that it has a lot to do with temperature, salinity, and the effect...
Curated OER
Environmental Differences
Young scholars observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
Lesson tow
Students study the ocean and its characteristics. For this oceans lesson students complete a lab activity and are able to predict temperature of certain depths.
Curated OER
Where's the Oxygen?
Young scholars study seawater and how temperature and salinity influence it. In this oxygen activity students complete a lab activity on dissolved oxygen.
Curated OER
Water Will, Water Way
Students complete a unit on biodiversity and their significance to pharmaceuticals. They

Salty Solutions
Students measure salt content in water. They determine salt content of four samples using a hydrometer.
Curated OER
Understanding Salinity
Young scholars discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers...
Curated OER
Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
