Curated OER
The Weight of Water
Learners 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.
Utah LessonPlans
Water, Please!
Students use a globe and cups of water to illustrated the amount of water versus land on earth and the amount of fresh versus salt water available to plants and animals.
Curated OER
Out of the Deep
Students observe, describe, and record characteristics of ocean animals (mammals and fish) and sea shells. They conduct an experiment comparing and contrasting sugar water, salt water and fresh water and create a mural of coral reef...
Curated OER
Marvelous Marshes of the Chesapeake
Third graders identify sources of salt water and fresh water that enter the Chesapeake Bay. They build a model watershed and describe how runoff enters the Bay.
Curated OER
To Be Salty Sea Ice Or Not
Students explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.
Curated OER
Making and Using a Hydrometer
Learners build a hydrometer to measure the densities of fresh and salt water samples. They record the water temperature and density and use the temperature, density, and salinity conversion graph to locate the salinity. Finally,...

Water Sources in Cape Verde and West Africa
Learners analyze the importance of a fresh water supply in Cape Verde, researching five methods of obtaining and conserving water there. Students create and present displays demonstrating their understanding of the methods of water...
Curated OER
Modeling Estuaries
Students create a model estuary. In this modeling estuaries lesson, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.
Curated OER
Make An Egg Float!
Students analyze density. In this density lesson plan, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.
Curated OER
Our Important Wetlands and Uplands
Students define wetlands. They list the benefits wetlans provide to man and nature. They compare types of wetlands that exist in northeast or east-central Florida. They list ways uplands affect wetlands and other water bodies.
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
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...
Curated OER
Channel Catfish
Students study the life and biology of the Channel Catfish. In this aquatic biology lesson, students will examine the external and internal features of the catfish along with their breeding habits and environment. This lesson includes...
Curated OER
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.
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
Water Water Everywhere and Not a Drop to Drink!
Learners describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Learners experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
What is an Estuary?
Students define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.
Curated OER
The Intertidal Zone: Tides and How Creatures Survive
Students study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson, students participate in classroom stations to learn about fresh water and salt water, cold...
Curated OER
Sink or Float?
Young scholars predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
Curated OER
Oddball Out: Fish
In this problem solving worksheet, students analyze a row of pictures of various fish to determine which creature is different from the others pictured. A bonus question asks students to identify which fish live in salt water but breed...
Curated OER
Aquatic Communities
Students watch a video about aquatic communities. They conduct an experiment that shows how movement of rivers change the landscape. They compare fresh and salt water communities and its wildlife.
Curated OER
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...
