Magnets at the Core

Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.

Make a Thunderstorm

When warm and cold air masses meet, a thunderstorm can grow. Thunderstorms also cause heavy rain, flash flooding, hail, strong winds and tornadoes. In this activity, you will learn about convection and how air moves.

Making a Cave

We usually think of caves forming as rocks are dissolved and the particles are washed away, leaving hollow spaces behind. This activity simulates the way that dissolution, a chemical weathering process, leads to the formation of caves.

Mapping a Refuge

A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.

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.

Model of a Well

Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.

Modeling an Oil Reserve

Abundant oil and natural gas form only where conditions in the Earth are just right. Doing this investigation will help you understand how geoscientists identify and explore petroleum-rich reserves.

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.
