Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Antarctica: Effects of Salinity on Icebergs
Learners investigate the effects of salinity on icebergs. For this hands on lesson, students design and conduct an investigation into how the amount of salt in ice affects its buoyancy.

Saltwater: Nifty Aqueous Colorful Layers
A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

Biocomplexity Lab Activity: Density and Buoyancy of
Pupils investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Pupils can research online different bodies of water (The Red Sea, The...

Salinity
Students take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.
Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties instructional activity, students read a background activity for the instructional activity and experiments to the topics. Students...

Water Properties of the Great Salt Lake
Fourth graders examine the ecosystem of the Great Salt Lake in this two-part instructional activity, completing a KWL chart before and after the field trip to the site. While there, they draw and write about their observations. To test...

Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.

Salinity and Brackish Water Systems
Young scholars are able to tell the difference between brackish and salt water. They also are able to distinguish water qualities specific to each type of water. Students answer various questions about all types of water.

Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Snow on Sea Ice
High schoolers examine different samples of ice and predict the amount of snow that has fallen in a given year. Using a calculator, they graph the various thicknesses. They analyze the graphs to determine the relationship between the...
