Measuring Glacial Retreat

The USGS has been studying glaciers in Glacier National Park since 1850. It is estimated that there were 150 glaciers in the park back then, and when the national park was established in 1910. Today only 25 glaciers remain.

 Scientists go back every year to repeat photographs, as well as to examine the ice and the ecology of the landscape to see how glacial retreat is affecting plant and animal species that live there.

Measuring Permeabilities of Soil, Sand, and Gravel

This investigation will help you to learn that different geologic materials have different characteristics.

Mineral Identification

Learn the characteristics of difference kinds of minerals in this hands on investigative activity.

Model of a Normal Fault

A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.

Modeling Earthquake Waves

An earthquake occurs when massive rock layers slide past each other. This motion makes enormous vibrations, which travel from the site of the earthquake in waves. In this activity, you will model how earthquakes move in three dimensions.

Natural Gas Formation

Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. In this investigation, you will make a simple model of how gases can form from decaying material. You will also explore the effects of temperature on gas formation.

Ocean Currents

In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.

Ocean Currents Change Our Earth

Ocean currents — the continuous, directed movement of ocean water — affect regional climates and alter the biological and chemical characteristics of seawater.

Parks Past, Present, and Future

Over Earth’s 4.5 billion-year history, tectonic upheavals and colliding plates formed mountain ranges and carved out basins. Forces of erosion and weathering have been at work to break down these landforms. Records of these processes are imprinted on the land and define distinctive landscapes around the United States and in its national parks.

Places on the Planet: Latitude and Longitude

Citizen scientists involved in the Geological Society of America's EarthCaching project (http://www.earthcache.org) use GPS technology and latitude and longitude coordinates to find special places on the Earth. This activity will help you learn how to find locations using latitude and longitude.
