Skill Building: Methodology and Analyses

Exploring Color Maps

Blue landmasses? Green clouds? Red ice shelves? Maybe you’ve seen a colorful map and said to yourself, that’s not how it looks in real life!

Exploring Energy with GIS

Geoscientists, energy researchers, and others in numerous careers and disciplines use GIS and its integrative nature to tackle these issues. You can, too.

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.

Exploring Porosity

Earth scientists play a vital role in harvesting the energy resources on which we all rely. When preparing to drill for oil, for example, geoscientists must assess many aspects of a rock stratum (layer). For example, they must figure out the volume of the rock’s pores, or empty spaces, as compared with the rock’s total volume. This is called the rock’s porosity. To help you understand porosity, think about different sizes of gravel. Which size gravel will have the greatest porosity? Why? In this activity, you will work in groups to explore the answers to these questions.

Finding Slope

Explore how the slope of land will effect water flow and life above ground in this activity from the Soil Science Society of America.

Flood!

Learn the dangers of flooding in this activity, where students explore soil porosity and permeability.

Geography of a Pencil

How is the world connected to the pencil you hold in your hand? Complete this activity to find out.

Geoheritage Via Google Street View

Google’s Street View is a rich resource for exploring geoheritage, since it visually transports us to many impressive sites across the country and around the world. Street View allows you to investigate a site, even one you don’t know well, which can lead to important insights. Of course, the real power and fun of Street View is that it allows you to explore by moving your visual perspective around the image.

Geologic Age

This activity will have students collect data, graph it, and compare the information to what they already know about radioactive elements and dating the planet's age.

Global Change: Where Land, Air and Water Meet

The atmosphere is a mixture of gases. Similarly, the world's oceans and fresh waters contain dissolved chemicals. Many substances dispersed in air or water are measured in parts per million. Some of these substances are colorless, odorless, and tasteless, yet even in small quantities they can be toxic. To develop an understanding of parts per million as a concept, teams of students will create successive dilutions of a solution to reach a parts-per-million concentration.
