Celebrate Wilderness

Learn the value and importance of the The Wilderness Act of 1964 with this online activity from the U.S. Fish and Wildlife Service.

Connect the Spheres

This activity will provide you with an introduction to a series of lessons — Survivor Earth — about water resources on Earth. You’ll investigate Earth systems by making observations in nature and identifying systems in the natural world. Ultimately, you will understand how the four spheres, or systems, on Earth — biosphere, hydrosphere, geosphere, and atmosphere — are interconnected.

Connecting With Nature

Go on an adventure with the Blue Goose, the symbol of the National Wildlife Refuge System!

Exploring 'Wild' Places with GIS

Regardless of where you live, engaging with the landscape means exploring spatial relationships between human and natural phenomena. Geographic information systems (GIS) technology ( provides an effective way to visualize and analyze these places, and your contact with them.

Exploring Change with GIS

On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block.

Exploring Geoheritage Through EarthCaching

An EarthCache is a special site that people can visit to learn about a unique geoscience feature or aspect of our Earth. Visitors to EarthCache sites can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.

Food Source

How diverse are the food sources in your community and where are they located? How far do they travel to reach you? Do you think the food sources for your community are sustainable? This multi-day activity explores these questions.

How Can You Test Your Soil?

As a citizen scientist, you can use a soil test kit to find out how much of each type of chemical is in your soil.

Looking for Wild Elements

In this activity, students will explore local places with wild elements, such as wildlife refuges. Students also will create maps showing spatial relationships between wild places and school, and they will find creative ways to record experiences.
