Land and People: Finding a Balance

This environmental study project allows a group of students to consider real environmental dilemmas concerning water use and provide solutions to these dilemmas.

Liquefaction

When it comes to slipping, sliding, and stability in soils, the key word is “liquefaction.”

During an event like an earthquake, liquefaction is the process by which saturated soil behaves like a liquid. This can be problematic, as a liquid soil loses structure and can cause buildings to sink, foundations to crack, and soil to slide down slopes all at once.

How does the type of soil affect how much a house will sink or shift during an earthquake? Conduct an experiment to test your ideas!

Magnets at the Core

Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.

Make Your Own Powers of Ten

Make your own Powers of Ten film like the classic science education movie by Charles and Ray Eames!

Making a Cave

We usually think of caves forming as rocks are dissolved and the particles are washed away, leaving hollow spaces behind. This activity simulates the way that dissolution, a chemical weathering process, leads to the formation of caves.

Making Caves: How Solution Caves Form

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.

Materials

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)
• Toothpick

Making Earth Art With Google Earth

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.

Mapping a Refuge

A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.

Mapping Quake Risk

Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data.
                

Mapping the Atmosphere

A map can represent data from an area on a flat surface. The part of our Earth system most frequently mapped is the atmosphere. Weather—the state of the atmosphere at a particular place and time—needs constant monitoring because it perpetually changes as weather systems evolve and move.

Awareness of what the weather is and is likely to be has numerous benefits. Weather can be hazardous, causing injuries, death, and loss of property. Weather maps are valuable analytical tools for informing people about current or future conditions.
