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
Where is Water Found?
Fourth graders examine the amount of water and its distribution on Earth. As a class, they brainstorm a list of where water can be found and classify the places according to salt water, fresh water or glaciers. They estimate how much...
Curated OER
A SALT WATER-Y WORLD
Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

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
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
Students 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
Middle schoolers 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
Students examine how salt water is more dense than fresh water through experimentation with eggs.
Curated OER
Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism instructional activity, 5th graders use potatoes to experiment with the effects of salty water in the body. Students discuss what osmosis is and record what...
Curated OER
Is the Hudson River Too Salty to Drink?
Students explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...
Curated OER
Surface Water and Groundwater
Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals.

Estuary Metaphors
Mixing metaphors into science. To begin, the instructor leads a discussion about estuaries to determine what the class already knows. Working in small groups, pupils determine how a selected object is similar to an estuary, how it...
Curated OER
Sink or Float Experiment
Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...
