### Connecting With Nature

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

The purpose of this activity is to give the player an introduction to the economics of mining. Each player buys "property," purchases the "mining equipment," pays for the "mining operation," and finally pays for the "reclamation." In return, the player receives money for the "ore mined." The object of the game is to develop the mine, safeguard the environment, and make as much money as possible.

### 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.

### Cracked Plates & Tectonics

In this activity, you’ll investigate dynamics in Earth’s crust that explain multiple Earth science phenomena.

### 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.

### Density of Minerals

Density is an intrinsic physical property of minerals that relates to the composition of the mineral and to the pattern in which the mineral’s atoms are arranged. “Intrinsic” means that the property is the same for the mineral, no matter what the size or shape of the sample. In this activity, students will measure and compare the densities of minerals.

### Design and Build a Water Filtration System

Access to clean drinking water is necessary for human health. But how do we get clean water? What happens to our water between its source and our faucet? What parts of the environment might act as a water filter? How can humans filter water to make it cleaner?

### Determining Mineral Reserves

Common things we use every day, like roads, sidewalks, schools, hospitals and homes ─ to name just a few ─ are made up of rocks and minerals. As a resource, they are called mineral reserves and include materials like sand, gravel, limestone, granite, and other aggregate and construction materials.
