Adaptations of Cave Critters Activity Source: Adapted with permission by National Park Service Caves with the National Natural Landmark (NNL) designation are some of the most fascinating of the thousands of caves around the world, and each one is unique. Caves’ special features are the product of various types of rock, their geologic setting, local climate, and time. This diversity in cave environments provides unique habitats for many different species of plants, animals, and other types of organisms. [Read More]

Find Your Park Activity Source: Adapted with permission by National Park Service. 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. [Read More]

Investigating Rock Types Activity Source: AAPG. Adapted with permission from “Investigating Earth Systems,” AGI. In any science, it is important to accurately and understandably describe your observations for others. Whether for advancing research or informing the public, communicating your work is critical. For geologists, this comes down to describing rocks’ colors, patterns, shapes and other features. These features may reveal evidence about the past, clues to their suitability for a construction project, or signs of valuable natural resources hidden within them. [Read More]

Land and People: Finding a Balance Activity Source: Adapted with permission by U.S. Geological Survey This environmental study project allows a group of students to consider real environmental dilemmas concerning water use and provide solutions to these dilemmas. The student packet (see Materials below) gives students most of the information they’ll need to answer the Focus Question, information such as maps, data, background, a reading about the region, and a description of the “Interested Parties,” or the various interest groups that have a stake in the outcome of the Focus Question.

Making Caves: How Solution Caves Form Activity Source: Adapted with permission by National Park Service 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. Materials Per student or small group: [Read More]

Shoebox Geologist Activity Source: Adapted with permission by National Park Service. Earth processes such as volcanic eruptions, floods, landslides, and glaciers leave behind evidence of their passing in the form of layers known as deposits . By studying deposits of recent geologic events, geologists are able to better understand older deposits and identify the processes that caused them. A fundamental principle of geology is the Law of Superposition, which states that younger layers will be deposited on top of older layers. [Read More]
