What's A Water Column Profile?
Students investigate water column data. In this earth science and seawater lesson, students determine how temperature, salinity, and density have an impact on sea water by viewing and analyzing data obtained from a number of websites....
Curated OER
Build a Solar Sill
Students explore how to generate fresh water from seawater. In this solar energy lesson, students use the power of the sun, evaporation, and condensation to generate freshwater. Students focus on the water challenges in Cape Verde and...
Curated OER
Sea Water Mixing and Sinking
Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

The Oceanographic Yo-Yo
Learners examine how oceanographers use chemical and physical parameters of seawater to locate hydrothermal vents. In this ocean lesson students complete an activity and worksheets.
Curated OER
Biomes: Freshwater & Seawater
Students observe organisms behavior and adaptations. In this biomes lesson students conduct fieldwork to determine water quality and answer questions about the differences between different habitats.

Oceanography Worksheet #1
If you are teaching physical oceanography to middle school earth scientists, here is a terrific multiple choice worksheet. Learners look at a diagram of a landscape created by glacial sediment deposition and the resulting ocean floor....
Curated OER
Mixtures
In this chemistry worksheet, students use the clues given at the bottom of the sheet to complete the crossword puzzle on mixtures. There are 18 clues to solve on the sheet.
Curated OER
Precipitates and Black Smokers
Students discuss how hydrothermal fluid is different from seawater and what happens to it as it passes through the oceanic crust. They observe and manipulate calcuim chloride and baking soda to comprehend how precipates form.
Curated OER
Ocean Water
In this ocean water worksheet, students use 6 given terms related to ocean water, early Earth and ocean components to complete the sentences. They also answer 4 questions about seawater, the effects of volcanoes on oceans and ocean life.
Howard Hughes Medical Institute
Ocean Acidification
Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....
Curated OER
Marine Fisheries Management
Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...
Curated OER
An Oceanographic Proxy
Students conduct experiments on a sample of sea water. In this oceanography lesson, students inquire how conductivity is used to approximate the salinity ocean water. Students construct their own conductivity meters and test solutions...
Curated OER
science: Light Up the Ocean
students investigate light levels under the ocean by conducting several simulations. After creating solutions representing seawater, they shine a light sensor on it to discover how light diffuses and is absorbed by the impurities in the...
Curated OER
The Iron Cheesebox
Students describe the oxidation/reduction reactions that are involved in the corrosion of iron in seawater. In this marine sanctuary lesson students study the steps in conserving marine archaeological artifacts.
Curated OER
Where's the Oxygen?
Young scholars study seawater and how temperature and salinity influence it. In this oxygen lesson students complete a lab activity on dissolved oxygen.
Curated OER
Making and Using a Hydrometer
Pupils 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, students...
Curated OER
Still Waters
Students construct a still to turn seawater into drinking water. They estimate the cost of distilling it. They investigate ways to make the conversion more efficient. They track the source of their home drinking water and make a map of...
Curated OER
Where Do Fish Live in the Hudson?
In this fish in the Hudson worksheet, middle schoolers read a brief excerpt about what types of fish can be found in the Hudson River in New York. They identify which fish are caught in greatest numbers and those caught in the most...
