Snapshot Day Definitions and Activities
Here is a document full of teaching notes on water quality and bodies of water that you can use in your ecology curriculum. It has information specific to the Hudson River area, but can easily be adapted to any local body of water....
NOAA
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...
Water
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
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
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
Freshwater Habitats
Learners take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their samples.
Curated OER
Communities and Biomes
In this biomes worksheet, students complete a crossword puzzle by figuring out the answers to 17 clues focused on communities and biomes.
Curated OER
Sea Level and the Terrapin
Students study the habitat of the terrapin. In this terrapin lesson, students create a diorama of the habitat of the terrapin. Students also simulate how it would look if people moved into the area and how predators can threaten terrapin...

Connecticut Wildlife: Biodiversity and Conservation Status of Our Vertebrate Populations
Learners explore the different types of vertebrates found in their area. In this environmental science lesson, students perform a case study on the Common Raven. They analyze data collected from research and create charts and graphs.
Curated OER
Sea and Ice Salinity
Students conduct an experiment. In this salinity lesson, students learn about sea ice, why it is important and how changing amounts can affect the sea. Students conduct an experiment to find out the effects of salinity on the...
Curated OER
Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
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
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...
Education Outside
Our Water Planet
Fresh water is a precious resource. Most kids don't realize how little of the water on Earth is actually drinkable. This lesson will help to illuminate them on this important topic. They discus the ratio of water to land, where most...
Curated OER
Do Salt Water Fish Drink?
Pupils conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.
Curated OER
Earth's Land and Water
Students describe physical characteristics of bodies of water and landforms. In this land and water lesson plan, students model land and water with modeling clay and also discuss why people live near bodies of water.

Locating the Salt Front - Section 1
In this salt front of the Hudson River learning exercise, 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...
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...
Polar Trec
Sea Ice Impact
The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...
Curated OER
Living Organisms as Indicators of Pollutants in Fresh Water Ecosystems
Students observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...
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.
