Density Stratification and Ocean Circulation

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Students explore marine life by conducting a rubber duck experiment. In this water currents lesson, students practice identifying latitude and longitude coordinates on a map and define the currents of major oceans. Students discuss the...

It's not long, but it's thorough! This PowerPoint takes 4th - 8th grade earth scientists deeper into the oceans. They learn about tide and current activity and the forces that drive them. They also discover how wind and the rotation of...

What is an air current, and what does it have to do with the sun? This is the focus of a video that explains how air currents are driven by the sun's energy to high and low pressure areas.

An unfortunate spill of 92,000 rubber ducks into the ocean in 1992 elicited invaluable information about global ocean currents as scientists tracked their journeys around the world. In this lesson, students first learn about the Ocean...

You are in a submarine and need to fix the currents to take you where you want to go. You want to get the key to the treasure chest full of gold!

A lesson where students learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or cold,...

In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface...

Ghost ships are real and are used to map ocean currents. Aye, thar be much to learn for landlubbers, sprogs, and buccaneers as well in a short video that offers scientific explanations for the amazing phenomenon of ghost ships.
