Essential Understanding

The student knows that the natural world includes rocks, soil, and water that can be observed in cycles, patterns, and systems.

Science Background

Water Resources: US Geological Survey (website) - Interactive information about the nation's water resources, including water data, publications and maps.

Elaboration Lessons and Extensions

Under the Deep Blue Sea: National Endowment for the Humanities (website) - After locating Earth's major oceans on a world map, students “dive underwater” to explore oceans and the plants and animals that live in the sea.

Assessment Ideas

Assess students’ understanding of natural water sources by collecting pictures of streams, lakes, oceans, water wells, rivers, ponds, etc. Have each student work with a partner to identify and describe the various sources of water.
