Some say a picture is worth a thousand words—even from a hundred miles away! Learners review satellite data to analyze ocean variables such as temperature, salinity, evaporation, and precipitation. They look for patterns in the data and...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Are the earth's oceans really just giant batteries, waiting for their energy to be harnessed? Middle school mechanical engineers will be shocked by the amazing amount of energy that forms around them after diving into part four of a...

Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Students explore reasons for varied salinity in bodies of water. In this geographical inquiry activity, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

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...

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...

Students investigate the distribution of the earth's water. They conduct a demonstration of water distribution, and create a pie graph to display the results.

Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...

Students design and conduct an experiment to determine the effect of salinity and temperature changes in the movement of ocean currents. In this earth science lesson, students record observations and collect data. They share their...

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.

Students describe the role of density in driving deep ocean currents and the density layers of the ocean. They determine that the ocean is one continuous body of water with global currents that interact, with water surrounding all...

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Here is a activity 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...

Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Students investigate the creatures of intertidal zones. They explore the adaptations species make to survive .

High schoolers conduct a variety of investigations to see how water, heat, and salinity affect the flow of the world's ocean currents,as well as, explore many factors that affect the flow of the world's ocean currents. They also describe...

Students study seawater and how temperature and salinity influence it.  In this oxygen lesson students complete a lab activity on dissolved oxygen. 

Learners explore the concept of finding the composition of seawater.  In this finding the composition of seawater instructional activity, students make a saturated salt water solution.  Learners discuss why there is variation...

Students 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.

Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.

Students study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.

The lesson seeks to intorduce to students the properties of salt water and how to create salt water. Teacher gives backgound information about salt water to students. From that point, students dscuss what elements are in salt water....
