Oceans of Fun
Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school lesson has clearly described activities, and all of the...
Curated OER
So Much Water, So Little to Drink
Students explore salt and fresh water. In this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid comprehension.

Exploring Density with Salt and Fresh Water: Part 5
This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...
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 activity comes with a wealth of...
Curated OER
Floating on Salt Water
Mixing substances together causes their properties to change. This resource illustrates that concept for fifth graders by having them consider four questions that have to do with buoyancy and boiling point. Learners begin to understand...

Boat Safety and Water Sports - Lesson 4 - Dangerous Sea Creatures
Lesson 4 is part of a 22 lesson unit on boat safety and water sports. This lesson is about dangerous sea creatures, mainly in the ocean. There is a link to find pictures of the creatures discussed. It is suggested to click on the...
Curated OER
North American Biomes
In this Science worksheet, learners color a biome map of North America. Students color the map by solving the clues listed on a separate sheet of paper.
Curated OER
The Great Ocean Conveyor
Students investigate water density. In this water density lesson, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.
Curated OER
Why Is The Sea Salty?
Students observe how salt concentration increases in water and how salt remains after water evaporates. In this salty sea lesson plan, student use rock salt, water, containers, and strainers to observe that salt increases each time new...
Curated OER
Salinity Lab
In this salinity activity, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.
Curated OER
Ocean Habitats
Students examine the water samples from a demonstration and discuss the difference between fresh and salt water. They draw different animals that live near or in the ocean and how humans can harm the ocean habitat. They draw pictures of...
Curated OER
Water Layering and Circulation
Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
Sunken Millions
This PowerPoint provides a game show format with multiple choice questions about fresh and salt water. Topics include sources of water, water geography, uses of water, and the water cycle.
Curated OER
Oceans
Students complete a unit of activities to learn about ocean life as well as improve their math and measurement skills. In this ocean life and math skills lesson, students complete 8 lessons to learn about ocean life and complete...
Curated OER
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
Learners 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
Students 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
Students 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
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
Learners 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 their...
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
Students 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.
