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...
Brine Shrimp: Getting to Know a Salt Water Arthropod
Gather small observations of arthropods. Using brine shrimp, pupils observe the life cycle of arthropods. Learners set up saltwater aquariums and observe the brine shrimp over a three-week period. To finish, they compare and contrast how...

How Dense is Salt Water?
Young schoolers explore the concept of linear regression. They determine the mass and density of salt water. Pupils add salt to water and record the density as salinity increases, and perform a linear regression on the data to model the...

Freshwater/Saltwater "Eggs-Periment"
Learners explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...
Curated OER
Saltwater Science
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...
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
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...

Do Salt Water Fish Drink?
Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.
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...
Biology Junction
Water Biomes
Water covers more than 70 percent of Earth's surface. Scholars learn about both freshwater and saltwater biomes in a simple presentation. They compare and contrast the differences in oxygen levels, food sources, and sunlight to better...
