Water Layering and 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...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

As an anticipatory set, young environmental technicians watch a video about how ocean temperatures seem to be changing along with the global climate. They perform a laboratory demonstration with the purpose of observing what happens to...

Sixth graders experiment to understand the ocean's currents.  In this ocean current activity, 6th graders complete an experiment with two bottles of water and an index card to discover information about the ocean current. ...

A unit where young scholars explore the seasons by researching the change in ocean temperature at different times of the year and different locations. Lesson includes teacher guide and student worksheets.

Learners compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...

Students examine the differences between air temperature and ground temperature.  In this investigative instructional activity students find NASA data on the Internet and use it to create a graph. 

There is more to the water cycle than simply rain and evaporation! The first installment in a four-part series explores the solar heating of the ocean through three satellite animations. The animations offer different views of the earth...

Go with the flow! The eighth installment in a 13-part series has earth science students dive in to the world's system of ocean currents. The interactive illustrates the different types and depths of currents, how wind and gravity...

What drives the ocean's motion? Get your class moving toward understanding by using this video. Viewers find that thermohaline circulation is caused by the concentration gradients of temperature and salinity. Using adorable animation in...
