Ocean Acidification
Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in...

Oceans of Fun
Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school lesson plan has clearly described activities, and all of the...
Curated OER
Salt Water vs. Fresh Water
Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...

Why Is The Sea Salty?
Students observe how salt concentration increases in water and how salt remains after water evaporates. For this salty sea lesson plan, student use rock salt, water, containers, and strainers to observe that salt increases each time new...
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.

Introduction to Coral Reefs
Students identify locations of coral reefs, both in the water and around the globe, identify relative depth of corals in the ocean by observing behavior of cold and warm saltwater, and create models of coral reefs.
Curated OER
Liquid Rainbow
Young scholars 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.

Is the Hudson River Too Salty to Drink?
Students explore reasons for varied salinity in bodies of water. In this geographical inquiry activity, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

Lesson tow
Learners study the ocean and its characteristics. In this oceans instructional activity students complete a lab activity and are able to predict temperature of certain depths.

A Funny Taste
Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.
Curated OER
Sea Activities
Students explore the sea. In this biology lesson plan, student investigate sea creatures, and sea water. Students discover how to convert sea water into fresh drinking water as well.
Curated OER
Out of the Deep
Students observe, describe, and record characteristics of ocean animals (mammals and fish) and sea shells. They conduct an experiment comparing and contrasting sugar water, salt water and fresh water and create a mural of coral reef...

Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
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
Water Layering and Circulation
Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
Finding the Deep Water Masses of the Atlantic Ocean
Young scholars describe the role of density in driving deep ocean currents and the density layers of the ocean. They determine that the ocean is one continuous body of water with global currents that interact, with water surrounding all...
Curated OER
Water Currents
Middle schoolers 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
Sea Water Mixing and Sinking
Learners 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
Sea Water Freeze
Middle schoolers 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
Water Pollution Prevention and Conservation
Students examine how to conserve water. They also discover how to prevent water pollution. They examine the Earth's water distribution as well.

A SALT WATER-Y WORLD
Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.
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.
