A Watery World
With about 70% of the earth's surface covered in oceans, it's fair to say that we live in a very wet world. Young scientists gain a better appreciation of this fact as they use maps to identify the world's ocean basins in the first...
Curated OER
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.

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...
San Francisco Public Utilities Commission
Desalination: Turning Salt Water into Fresh Water
How does San Francisco supply its citizens with enough water, even during a drought? Learn about reservoirs and why desalination could be a good solution with a reading passage about water conservation. After kids finish the...

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...
Curated OER
Environment: Water & Air
The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

North American Biomes
In this Science worksheet, students 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 worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.
Curated OER
The Caspian Sea
In this comprehension and geography worksheet, students read an article about the Caspian Sea, identifying where it is located and what countries surround it. Then they describe three parts of the sea, what are tributaries, and how many...
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.
