Using paper patterns, students are able to construct a model that depicts Karst topography, including typical features such as caves, limestone bedrock, sink holes, and springs. The accompanying Teachers Guide provides extensive background information about the dissolutional processes that form caves. Information is also provided about unique animals found in caves and the importance of understanding ... Full description.

This site describes how snow and ice runoff become surface water and emphasizes how runoff from snowmelt is a major component of the global movement of water. A hydrograph from the U.S. Geological Survey shows a four-year time series of streamflow and illustrates how runoff from snowmelt affects the daily mean values, particularly at certain times of the year.

Students in this lesson will be introduced to the concept of tides and tidal forces. By viewing a related applet which visualizes the relationship between the Earth, moon and tides, students will gain an understanding of why the Earth experiences tides. In the process they are asked to observe and explain how the relative positions of Earth, the moon, and the sun are responsible for the moon phases, ... Full description.

This site provides a discussion of the downward movement, or infiltration, of water from the surface into soil or porous rock. Graphics illustrate the processes affecting infiltration, including precipitation, soil characteristics and saturation, land cover, slope, and evapotranspiration. Links to additional sources of information are also provided. Full description.

In this activity, students build an edible aquifer using ice cream, food coloring, and other ingredients to represent the various layers. They will learn about groundwater, water tables, confining layers, contamination, and recharge. A link to a glossary of groundwater terms is provided. Full description.

In this activity, students construct a "comet" from ingredients similar to those found in actual comets. They will learn about the behavior of a real comet by observing their model as the dry ice sublimates, and understand the concept of scale as they compare the size of their model to the size of a real comet. A list of materials and instructions are provided. This activity can be performed as a ... Full description.
