Curated OER
Sea Ice
Learners observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes...

To Be Salty Sea Ice Or Not
Middle schoolers explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.

Ocean and Great Lakes Literacy: Principle 7
Your mission, should you choose to accept it, is to take your class on an underwater adventure. The final installment in a seven-part series involving salt and freshwater bodies takes junior oceanographers below the surface in...
Curated OER
Properties of Fresh and Sea Water
Middle schoolers work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
Tracking the Salt Front
Using the Hudson River as the focus, learners discuss the difference between salt water and fresh water environments, analyze maps and graphs, and complete addition and subtraction problems. This lesson comes with a wealth of...
Curated OER
Sea Water Mixing and Sinking
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.

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...

Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
Curated OER
Ocean Floor Model
Students construct a simulated model of the ocean floor in a shoe box. They determine that the floor of the ocean is composed of hills, plains, ridges, trenches, and sea mounts. They draw out a plan for their ocean floor which includes...
Curated OER
Sea Level and the Terrapin
Students study the habitat of the terrapin. In this terrapin lesson plan, students create a diorama of the habitat of the terrapin. Students also simulate how it would look if people moved into the area and how predators can threaten...
Curated OER
Summer Intern
Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

A Funny Taste
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.
Curated OER
Understanding the Ice
Learners explore the concept of sea ice. In this sea ice activity, students interview arctic hunters to regarding the sea ice safety and attributes.
Curated OER
Ocean Water
Given data about the composition of ocean water, students complete 5 different questions using a provded table that relate to the ocean water (with elements Chloride, Sodium, Sulfate, and Magnesium). Some questions require calculation,...

The Edge of the Lake
Second graders explore the geography of Nevada. In this map-making lesson, 2nd graders use salt dough to create a relief map of Nevada. Students label the landforms and bodies of water that are studied and specified in the lesson.
Curated OER
Why is the Sea Salty?
Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.
