Discovering Fossils

A fossil is any evidence of past life preserved in a geologic context, such as within rock or sediment. This activity allows you to explore the process used by paleontologists — scientists who study fossils to understand ancient landscapes, climate, and life on Earth — to find and identify fossils.

Drill Site Dilemma

This activity gives your students a glimpse at the difficulty of seafloor surveying, as well as the challenges the JOIDES Resolution faces during each expedition. Your students also will learn about latitude and longitude and plotting coordinates.

Earth's Hydrologic Cycle

The ocean is the key element in Earth's hydrologic cycle (water cycle). Students will construct a simple model of the hydrologic cycle to help them visualize and understand the movement of liquid water and heat.

Exploring Caves

An instructional unit on caves for grades K-3. Five short chapters, with follow-up activities and lessons.

Gold Panning

Travel back in time and try your luck panning for 'gold' in this fun mineral activity.

Groundwater Movement

Water that accumulates beneath the surface of the Earth is called groundwater. Contrary to popular belief, groundwater does not form underground "rivers," but is actually found in the small spaces and cracks between rocks and other material such as sand and gravel. The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.

How Much Soil Is There?

All living things depend on soil to live. But how much soil is there?

It’s the “Rain,” Man

People find inspiration in many different places and things. Among them is taking joy in sensing the Earth around you. Feel the breeze on your face. Take in the fresh smell of the air after a spring rain. Use your hands to build something. Wherever you live you can get outside, savor your surroundings and observe what makes up the rhythms of the place you live.

Look Up!

The following activity is designed to help you learn to listen, read, and communicate in both written and oral formats about the sky.

Making Caves: How Solution Caves Form

Caves form through a variety of natural processes depending on their local geology and climate. Flowing lava, melting ice, dissolving rock, and crashing waves are the major processes that form these wondrous environments. In this activity, students will observe a model of how the most common type of cave — solution caves — form.


Per student or small group:
• 4 ounces of modeling clay
• Sugar cubes (3-6 per cave)
• See-through bowl (cutting the top off a 2-liter bottle works well)
• Toothpick
