Water Density and Salinity
Middle schoolers observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the...
Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Layering of Water
Students examine what happens when different types of water meet. In groups, they participate in an activity in which they combine different percentages of salt, fresh and brackish water and record their observations. They let the...
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...

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.
Curated OER
Sea Water Mixing and Sinking
Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Water, Water Everywhere, and Nary a Drop to Drink!
Students sing the continent song and locate oceans between the continents on a map. They read "They Earth is Mostly Ocean" and copy notes into their journals. They watch a demonstration of water and saltwater evaporated to see what is...
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Water Currents
Middle schoolers demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the lesson plan.

Why is the Ocean Salty?
For this ocean salt worksheet, students read about the processes that have lead to the salt content in the ocean. Then students complete 5 short answer questions.
Curated OER
A Funny Taste
Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.

Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
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
Salinity
Learners 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
Introduction to Coral Reefs
Young scholars identify locations of coral reefs, both in the water and around the globe, identify relative depth of corals in the ocean by observing behavior of cold and warm saltwater, and create models of coral reefs.
