Connecting With Nature

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

Conservation in Action

Join the conservation movement with U.S. Fish and Wildlife Service!

Core Sampling

Drilling is the only way to be sure that oil and gas fields exist and exactly what is present in the formation. Core samples reveal the physical and chemical nature of the rock. In this activity, you will create a model formation and “drill” for samples.

Dangerous Atmosphere

How much of a danger does severe weather pose for the area where you live? You can compute the answer yourself in this exercise.

Dating Popcorn

How do geologists understand the Earth’s history? In part, they measure the age of rocks and other natural materials by dating techniques. They can date rocks by gauging the amount of decay of radioactive elements. You can simulate the dating process with popcorn.

Deep-Sea Drilling

This activity enables students to estimate and calculate scales of distance and length as used by ocean drilling scientists.

Dig Into Soil

Learn how soil scientists observe and record data and how that information is useful to farmers, builders, and others in order to use the land appropriately.

Drill Site Dilemma

This activity gives your students a glimpse at the difficulty of seafloor surveying, as well as the challenges the JOIDES Resolution faces during each expedition. Your students also will learn about latitude and longitude and plotting coordinates.

Dynamic Wetlands

Learn about the importance of wet and dry seasons in wetland ecology. Students will learn to understand the wetlands as precious ecosystems.

Earth's Hydrologic Cycle

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.
