Presenting the Water Cycle
Third graders complete a unit of study about the water cycle using both print and Internet based resources. They examine fresh and salt water and complete an online quiz before developing a multimedia presentation highlighting the phases...
Curated OER
Sea Water Freeze
Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
Soap, Wood, and Water
Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Superhydrophobicity – The Lotus Effect
Discover and demonstrate the Lotus Effect and superhydrophobic surfaces with the eighth installment of a nine-part series that teaches scholars about surfaces that exhibit superhydrophobicity. The lesson continues also describes...
Curated OER
Dispersement of Particles: Diffusion and Osmosis
Students explore the dispersement of particles. In this science lesson plan, students describe the many ways in which particles move and transfer from one source to other areas.
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 instructional activity students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
Curated OER
A Fish Tale
Students investigate the lives of fish. In this biology lesson plan, students demonstrate how fish cells respond to fresh and salty water, determine the age of a fish and if temperature effects the movement of a fish's operculum (gill...
Curated OER
A Fish Tale
Students conduct an experiment. In this fish lesson, students discover how fish cells respond to fresh and salty water and if temperature effect the movement of a fish's gills. Students also identify the characteristics of a fish.
Curated OER
Plant And Animal Adaptations
Students examine plant and animal life while looking at the environments the organismisms live in. They determine how form follows function by looking an aquatic turtle and noticing its feature of adaptation features. They work in groups...
Curated OER
Salt Marsh Plants and Animals
In this salt march plant and animals instructional activity, students read descriptions of animals, then match each to its picture. Students then read about tidal animals and choose which animals in picture are most likely to be in a...
Curated OER
Modeling Estuaries
Students create a model estuary. In this modeling estuaries lesson plan, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.
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 plan, students participate in classroom stations to learn about fresh water and salt water, cold...
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
Sink or Float?
Students 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
Microfishing
Students use a simple method to collect living microorganisms from natural and/or artificial environments and develop skills in microscopy, observation, drawing, speculation, hypothesizing, oral presentation, and raising questions.
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
Which Fish Where?
Focusing on the fish in the Hudson River Estuary, this activity could be used to practice reading, graphing ,and critical-thinking skills. Answering the 6 questions should be interesting for students due to the interesting subject matter.
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
The Floating Egg Problem
This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...
Curated OER
Fish Communities in the Hudson
Learning to read data tables is an important skill. Use this resource for your third, fourth, or fifth graders. Learners will will study tables of fish collection data to draw conclusions. The data is based on fish environments in 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
Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
Curated OER
Building A Solar Still
Students investigate the water cycle by viewing an online video. For this drinking water lesson, students create solar stills at their campus in order to purify water that is tainted. Students view a video on their computers...
