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

Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism lesson, 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 plan, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why...
Curated OER
Surface Water and Groundwater
Students examine distribution of water and minerals. In this surface and groundwater activity, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals.

Water Cycle
Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

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...
National Wildlife Federation
Water, Water Everywhere?
Visibly display the location of the water in the world. Using 12 liters of water to represent the total amount of water in the world, the class measures out the water located in different areas, such as the ocean and ice caps. Class...

Global Water Supply Elementary School Curriculum
Water is the focus of an interdisciplinary unit that brings awareness to its daily use around the world and the importance of conservation. Worksheets challenge scholars to match words and definitions, trace, complete a maze, and solve a...
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...
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
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
Students 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,...
Curated OER
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 activity, 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
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. In this density lesson plan, 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...
Curated OER
Channel Catfish
Students study the life and biology of the Channel Catfish. In this aquatic biology instructional activity, students will examine the external and internal features of the catfish along with their breeding habits and environment. This...
Curated OER
Water Water Everywhere and Not a Drop to Drink!
Middle schoolers 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
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
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
Teacher's Guide For: Water Temperature and Salinity Experiment
Students 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?
Pupils 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.
