Ocean Water
In this ocean water worksheet, students will look at how oceans affect us, how oceans originated, and what oceans are made up of. This worksheet has 15 fill in the blank questions.
Curated OER
Chillin' Out with Freezing Point Depression
Students examine the freezing point depression of salt water by making ice cream. Lab activity begins with students layering a bowl with ice and salt around an empty cup before adding a mystery solution to the cup. They take the...
Curated OER
The Floating Golf Ball
Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...
Curated OER
Salt Water Wedge
Pupils conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Temperature Effects on Solubility
Learners determine the solubility of salt in water at three different temperatures and graph the results. They use the following skills: observing, inferring, and graphing.
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
Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
Curated OER
Jeannette
Middle schoolers develop hypothesis about what might happen when salt water is frozen. In groups, they freeze ice samples with different salt concentrations. They use the internet to research the situation of the Jeannette to discover...
Curated OER
Great Salt Lake
Third graders are introduced to the Great Salt Lake (GSL) environment and the various components of it. They make observations about algae and its environment and discuss why it is considered a living organism and various components of...
Curated OER
New Jersey Estuaries
Learners experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.
Curated OER
Sink or Float Experiment
Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...
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.

Science Buddies: How Salty Is the Sea?
Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. Bodies of freshwater also contain some salt, but much less compared to oceans. In this experiment you...

Science Buddies: From Brine to Beverage: Solar Powered Salt Removal
In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.

Mit: Blossoms: Will an Ice Cube Melt Faster in Freshwater or Saltwater?
Engage learners in the study of the ocean and saltwater with these activities. Students will see that saltwater has different physical properties than freshwater - mainly density. This lesson can serve as a springboard into other...

Texas Instruments: Finding the % Salt in Seawater
In this experiment, students are asked to collect data in order to prepare a calibration curve showing the relationship between the percentage of salt and the mass of salt water. Using this graph, students will be able to determine the...
