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.

Logs of Straw - Dendrocronology

Dendrochronologists use tree rings to go back in time to learn more about past climate. Using straws to recreate tree rings, you can learn how dendrochronologists work.

Magnets at the Core

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

Make Your Own Compass

Learn how to make a compass using household objects!

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.

Mapping Quake Risk

Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data.

Mapping the Atmosphere

A map can represent data from an area on a flat surface. The part of our Earth system most frequently mapped is the atmosphere. Weather—the state of the atmosphere at a particular place and time—needs constant monitoring because it perpetually changes as weather systems evolve and move.

Awareness of what the weather is and is likely to be has numerous benefits. Weather can be hazardous, causing injuries, death, and loss of property. Weather maps are valuable analytical tools for informing people about current or future conditions.

Mapping Vertical Movements

This activity uses “flubber” to demonstrate the visco-elastic properties of the Earth’s lithosphere and shows isostatic rebound in action.

Measure for Measure

Geoscientists use special boats to conduct research at sea. One of these boats is named the JOIDES Resolution (JR). Unlike most oceangoing vessels, the JR has a flat bottom, a 6.4-meter hole in the middle, 12 laboratories, and a derrick towering 67 meters above the waterline! Why? So scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor. What for? In hopes of discovering clues about Earth's history and structure, life in the deep biosphere, past climate change, earthquakes and natural resources.

Mineral Electrical Conductivity

People must mine minerals to provide all kinds of materials that we depend on in our lives. The purpose of this activity is to test the conductivity of various minerals with a simple electrical circuit and draw conclusions about which ones would be used in electronics.
