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...

Ocean Layers I
How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Earth's Water Sources
General facts about Earth's water sources, human use, and the water cycle are outlined by this presentation. Slide three has a grammatical error and slide nine refers to the local watershed of the author, so you will need to make a few...

So Much Water, So Little to Drink
Students explore salt and fresh water. In this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid comprehension.

Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

How Much Ocean?
In this ocean worksheet, students are given a map of the world and they predict the amount of water that covers the Earth's surface. They count the total number of squares on the given map that represent the water and they land and they...

The Thermal Layers of Oceans
How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

Ocean Streams
The instructions for demonstrating ocean turnover are provided in this resource. You could set this up for your earth science class as part of a lecture on convection currents or as an explanation of how ocean currents form. An animation...

Ocean Zones
How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

Finding the Deep Water Masses of the Atlantic Ocean
Students 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 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
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.
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Air and Water in the Environment
Students demonstrate an awareness of air as a substance that surrounds us and takes up space, and whose movement we feel as wind. They predict and describe how local weather conditions affect living things, including themselves.
