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.

pH Readings and Salinity Readings of Water From Three Locations Within the Neponset River Watershed
Sixth graders test the ph levels of water from three different water environments within the Neponset River Watershed. They discuss the three different water environments, take pH measurements of the three samples, and predict which...
Curated OER
Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. In this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different layers.
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Biocomplexity Lab Activity: Creating Salt Water
The instructional activity seeks to intorduce to students the properties of salt water and how to create salt water. Teacher gives backgound information about salt water to students. From that point, students dscuss what elements are...
Curated OER
Getting Physical with Estuaries
Students study estuaries and how the physical factors change over time. In this investigative lesson students use a website to gain knowledge of estuaries then in groups they create and present their charts.

Oceans of Energy
Are the earth's oceans really just giant batteries, waiting for their energy to be harnessed? Middle school mechanical engineers will be shocked by the amazing amount of energy that forms around them after diving into part four of a...
NOAA
A Quest for Anomalies
Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...
Polar Trec
Nature's Density Column
Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...
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
Weather, Sea Level Rise and Climate Change Course
Young scholars explain the impact of glacial melting to global climate change. In this environmental science instructional activity, students design an experiment to investigate the effect of salinity change to melting glaciers. They...
Curated OER
Monitoring Estuarine Water Quality
Young scholars analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...
Curated OER
The Effects of Storms
An excellent way to review a chapter or unit on storms, this activity features vocabulary review (gust, evacuation, storm surge, salinity), concept review (effects and details about hurricanes), skills/process review (normal high tide...
Curated OER
We All Scream for Ice Cream
Students make ice cream while experimenting with the freezing point of water. They experiment with different amounts of salt.
Curated OER
Estuarine Currents
Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
Curated OER
Desalination: Creating a Solar Still
To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...
Curated OER
Water Currents
Pupils demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the lesson.
Curated OER
Hatching Brine Shrimp
Learners experiment with temperature and salinity to detect favorable environments for hatching brine shrimp eggs. They make some predictions about which environments will yield the most hatched brine shrimp and record the number of...
