The ocean is the key element in Earth's hydrologic cycle (water cycle). Students will construct a simple model of the hydrologic cycle to help them visualize and understand the movement of liquid water and heat.
An instructional unit on caves for grades K-3. Five short chapters, with follow-up activities and lessons.
Travel back in time and try your luck panning for 'gold' in this fun mineral activity.
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?
People find inspiration in many different places and things. Among them is taking joy in sensing the Earth around you. Feel the breeze on your face. Take in the fresh smell of the air after a spring rain. Use your hands to build something. Wherever you live you can get outside, savor your surroundings and observe what makes up the rhythms of the place you live.
The following activity is designed to help you learn to listen, read, and communicate in both written and oral formats about the sky.
Caves form through a variety of natural processes depending on their local geology and climate. Flowing lava, melting ice, dissolving rock, and crashing waves are the major processes that form these wondrous environments. In this activity, students will observe a model of how the most common type of cave — solution caves — form.
Per student or small group:
• 4 ounces of modeling clay
• Sugar cubes (3-6 per cave)
• See-through bowl (cutting the top off a 2-liter bottle works well)
If you were an alien visiting Earth for the first time, you might remark on the diverse and incredible landscapes and patterns around majestic mountains, green forests, rolling grasslands, and turquoise oceans. You also might recognize geometries of civilization and changing weather patterns. All this can be explored from space. In this activity you will explore our planet using Google Earth and locate natural and man-made patterns and landscapes on Earth’s surface that inspire you.
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.
