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...

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.

Kids for Conservation Lesson 1
Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...
Curated OER
Salt Water vs. Fresh Water
Middle schoolers explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they...
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
The Intertidal Zone: Tides and How Creatures Survive
Young scholars study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone instructional activity, students participate in classroom stations to learn about fresh water and...

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.
Curated OER
The Weight of Water
Young scholars examine how salt water is more dense than fresh water through experimentation with eggs.
