In this module, students carry out a number of activities that demonstrate the concepts of evaporation, condensation, precipitation, and soil moisture and runoff. The students then construct a terrarium as a way to observe the water cycle as a whole. Immediately following this, students use the Internet to acquire Real Time Data from the Olympic Peninsula in Washington which they can then use to describe ... Full description.

This activity allows students to explore the roles of oil and water in the Middle East, especially in Iraq. Students will use maps to look at the distribution of oil in the Middle East and discuss what it means for the different countries in the region. They will also examine how water has influenced the region historically and politically. Finally, they will study specific aspects of Iraq's struggles ... Full description.

In this lesson plan students learn about ocean waves. They will begin by learning the components of a wave and will then discuss the meaning of wave height and wavelength. A demonstration will spark discussion about how to make waves, and an activity with the National Geographic Wave Simulator will allow students to experiment with creating waves of varying sizes.

The Gulf of Maine Aquarium hosts this two-part activity. The focus is on seasonal changes in the mass balance of the Antarctic Ice Sheet. Part 1 uses an atlas and satellite imagery to examine the geography of the region and the changing boundaries of the ice sheet. Part 2 tracks annual changes in sea ice. There is an animation page showing changes in ice cover around Antarctica during 1991, and links ... Full description.

The goal of the PALEOMAP Project is to illustrate the plate tectonic development of the ocean basins and continents, as well as the changing distribution of land and sea during the past 1100 million years. In the section on Earth history you can select any time period, read about that period, and see the plate distribution during that period. There is also a section on climate history where you can ...
