Locating the Salt Front - Section 1
For this salt front of the Hudson River worksheet, 7th graders first read an excerpt about the lower portion of the Hudson River that is an estuary. Then they use a colored pencil to plot salinity data from the table shown on a graph,...
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...

Heating and Cooling of Land Forms
Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...
Curated OER
Sea Water Freeze
Learners observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Georgian Court University
Introduction to Marsh Ecology
Compare and contrast the characteristics of fresh and salt water marshes. After exploring the typical plants and animals found in each marsh type, participants use a set of flash cards to sort into fresh and salt water marsh life. Their...
Curated OER
Summer Intern
Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...
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.
Curated OER
It's Too Salty!
Students examine water shortage and the process of changing salt water to fresh water. They examine a world map, define key vocabulary terms, conduct experiments involving seeds and salt water and creating distilled water, and illustrate...
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
Fresh Water From the Oceans?
Students participate in an activity in which they demonstrate how the evaporations of water from the oceans results in fresh water in the form of rain. They create a saltwater solution in a flask and boil the water until most of the...
Curated OER
What is a River?
Young scholars study the various types of bodies of water: rivers, oceans, lakes and ponds. They observe models of each and then use clues to discuss how they are alike and different. They imagine they have found a new planet and draw...
Curated OER
Water Wars
In this water worksheet, students match 5 water uses to their definitions, they unscramble 3 terms related to water supply to complete sentences and they answer 2 questions about water diversion.
Curated OER
Oceanography
Second graders identify saltwater and freshwater habitats and the resources found in them. They compare and contrast the two habitats and discuss their findings. They discover the resources bodies of water can provide.
Curated OER
A SALT WATER-Y WORLD
High schoolers observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

Water from the Well
How much water does it take to brush your teeth? How about to wash your clothes? Perform an experiment that measures water usage in everyday tasks and compares them to the days before indoor plumbing, specifically the California gold...
Core Knowledge Foundation
Animals and Habitats Tell It Again!™ Read-Aloud Anthology
A read-aloud anthology explores various habitats and the animals that inhabit them, from the Artic to the desert, the forest, and bodies of water. First graders listen to and discuss texts and complete word work. Each lesson offers...
Curated OER
Aquatic Organisms
Students create a poster describing the five characteristics of a salt water organism compared to a fresh water organism.
Curated OER
Venn Diagram: Comparing Water
In this Venn diagram comparison worksheet, students compare salt water and fresh water. Worksheet contains a link to additional activities.
Curated OER
Diaper Challenge
Middle schoolers compare the absorbency of a regular diaper and a swim diaper in fresh water and salt water. In this absorbency lesson plan, students mass the diapers and place them in water and determine the change in mass. They do the...
Curated OER
The Sun as the Driving Force of the Water Cycle
Students study the water cycle and how the sun is an important factor. In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
Curated OER
One World Ocean
Learners compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...
Curated OER
Aquatic Organisms and Their Habitats
Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.
