Glacier Slide Activity Source: National Park Service Objective You will be able to describe how a glacier carves an area and label the characteristics formed by the glacier’s movement. Background There are many glaciers all over Alaska. Flying into Lake Clark National Park and Preserve through Lake Clark Pass, you will see many glaciers. These glaciers were growing during the last Ice Age. Now many are retreating because Alaska is getting warmer. [Read More]

It’s About Time Activity Source: National Park Service. Adapted with permission. Geologic time can be difficult for people to understand. Our own lives are so short when we compare them to the age of the Earth, that the hundreds of millions of years of geologic time are almost too much to grasp. But for us to understand Earth activities today, we must have at least some basic understanding of geologic time. [Read More]

It’s the “Rain,” Man Activity Source: National Oceanic and Atmospheric Administration. Adapted with permission. 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. [Read More]

Looking for Wild Elements Activity Source: Fish & Wildlife Service. Adapted with permission. For the Teacher: Few schools are within walking distance of a federally designated wilderness. However, many schools are within walking distance of land with wild elements. Students can look for examples of places with wild elements on or near their school grounds. Then they can duplicate the activity in a wilder landscape, such as those found on national wildlife refuges. [Read More]

Magnets at the Core Activity Source: Consortium for Ocean Leadership. Adapted with permission. Over time, Earth’s magnetic poles change strength and location. They also completely reverse directions episodically. The north magnetic pole is currently moving northwest at 40 kilometers per year. It moved from 81.3° N, 110.8° W in 2001 to 82.7° N, 114.4° W in 2005. (Learn more at www.ngdc.noaa.gov/geomag/faqgeom.shtml.) The strength and direction of Earth’s magnetic field at any time in geologic history is recorded by sediments and oceanic crust deposited or formed at that time. [Read More]

Map-Making Basics Activity Source: U.S. Geological Survey, 2006. Adapted with permission. Background Maps are two-dimensional ways of representing information about the natural and built world from a “top-down” perspective. You are probably familiar with road maps that show where roads go and which roads intersect with others and where. You also may have seen weather maps, which show weather patterns across a specific geographic area, or political maps, which show where borders are for countries and areas within those countries.

Mapping a Refuge Activity Source: National Energy Education Development Project. Provided by the U.S. Fish and Wildlife Service. Adapted with permission. The National Wildlife Refuge System, managed by the U.S. Fish and Wildlife Service, is the world’s premier system of public lands and waters set aside to conserve America’s fish, wildlife, and plants. Why not visit a national wildlife refuge (www.fws.gov/refuges) in or near your community? A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife.

Places on the Planet: Latitude and Longitude Activity Source: Geological Society of America, 2006. Adapted with permission. Background You may have seen or used Global Positioning System (GPS) devices in cars or on camping trips. These devices use data from satellites orbiting the Earth to locate places on our planet. GPS devices describe the locations to us in the form of latitude and longitude coordinates. Citizen scientists involved in the Geological Society of America’s EarthCaching project (http://www.

Plant an Ozone Monitoring Garden Activity Source: Adapted with permission from NASA Aura Education and Public Outreach. To measure ozone in the Earth’s atmosphere, NASA built the approximately 6,500-pound Aura satellite. The spacecraft carries four high-tech instruments that scan the globe from more than 700 kilometers above the planet. For students, there is an easy way to investigate ozone in their own neighborhood. It’s as simple as growing a few carefully selected plants. [Read More]

Soil, Plants, and the Energy Cycle Activity Source: Soil Science Society of America. Adapted with permission. Soils are critical for many aspects of our daily life. They provide food such as grains, vegetables, and animal feed. They provide fiber for clothing, as in cotton, flax-linen, and hemp. And they provide shelter materials like wood and brick. But did you realize that soils also are an important part of the energy cycle? [Read More]
