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.

Eye of the Storm

A tropical storm is brewing in the Atlantic Ocean. It’s causing rain and thunderstorms over the Caribbean, and it will soon be a tropical depression — the beginning of a hurricane. By the time Hurricane Mitch leaves the Central America, more than 11,000 people will be dead and as many as 18,000 more will be missing.

Find a Feature Challenge

Geoscience is for everyone! And everyone can accept the Find a Feature Challenge!

What is the shape of the land in your neighborhood? Is it flat or hilly? Do you see small or large rocks? Are they rough or smooth? What color is the soil, and where does the water flow?

Find Your Park

A park can be many different things to many different people. For many people, Canyonlands National Park is a favorite showcase of geology.

In each of the park’s districts, you can see the remarkable effects of millions of years of erosion on a landscape of sedimentary rock. The Green River has carved a channel out of rock layers deposited nearly 300 million years ago creating an open book for earth science enthusiast of all ages.

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.

Food Source

How diverse are the food sources in your community and where are they located? How far do they travel to reach you? Do you think the food sources for your community are sustainable? This multi-day activity explores these questions.

Fossil Formation

Have you ever seen a fossil? A fossil is any evidence of past life preserved in sediments or rocks. Do you think you could have dinosaur fossils in your family car’s gas tank? Did you ever hear that oil and natural gas are “fossil fuels”? Do you think oil and natural gas can be made from fossils? How long do you think it takes fossil fuel to form?

Freddy the Fish

Human activities can have a detrimental effect on animal habitats. Young students can witness the effect of water pollution on river habitats.
