How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

It's an ocean rescue mission! Groups must find a pilot downed off the coast of the Chesapeake Bay. Rescuers must determine the distance needed to travel as well as the heading to get to the pilot's last known position. Taking...

Fourth graders examine the effects of waves on coastal land. They discover how water's power can change the appearance of land formations.

Scholars build a compass using a needle, cork, magnet, and a water-filled cup in order to locate the magnetic north and south.

Students study the changes in land formations caused by water erosion. They work in groups to build a model of a mountain composed of materials that will best withstand water erosion.

A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in...

In this energy science fair project, the student will use ocean buoy data to determine if any locations along the coasts of the United States are appropriate for building wave energy power systems.

Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within...

[Free Registration/Login Required] An informational text about huge waves created by an undersea ridge off the coast of California called Cortes Bank. A question sheet is available to help students build skills in reading comprehension.

Students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches the continental shelf. Students make villages of model...
