Water that accumulates beneath the surface of the Earth is called groundwater. Contrary to popular belief, groundwater does not form underground "rivers," but is actually found in the small spaces and cracks between rocks and other material such as sand and gravel. The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.
All living things depend on soil to live. But how much soil is there?
The following activity is designed to help you learn to listen, read, and communicate in both written and oral formats about the sky.
Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.
Learn about fossil preservation, paleontology, and stratigraphy in this detailed activity from the USGS.
In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.
Crucial to our existence, water sustains all life on Earth. Following the old adage, "What goes around comes around," water moves continuously through the stages of the hydrologic cycle (evaporation, condensation, and precipitation). How does our drinking water fit into this hydrologic cycle? Where did the water we drink fall as precipitation? Did this water percolate down into the ground as part of a groundwater system, or did it remain on the surface as part of a surface water system? What path did this water follow in order to become our drinking water? This lesson will explore the hydrologic cycle and water's journey to our glass.
Each group will design a water filtration system and present to the class, why they picked their design.
Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology.
