Geologic Age Activity Source: Adapted from the USGS Learning Web Lesson Plans Background At the close of the 18th century, the haze of fantasy and mysticism that tended to obscure the true nature of the Earth was being swept away. Careful studies by scientists showed that rocks had diverse origins. Some rock layers, containing clearly identifiable fossil remains of fish and other forms of aquatic animal and plant life, originally formed in the ocean. [Read More]

Geologic Time Scale Analogy Activity Source: Ritger, S.D. and R.H. Cummins. 1991. Using student-created metaphors to comprehend geologic time. Journal of Geological Education. 9:9-11. Purpose To introduce students to the vastness of [geologic time](/content/geological- time-scale) and the concept of scale. Background Unraveling time and the Earth’s biologic history are arguably geology’s most important contributions to humanity. Yet it is very difficult for humans to appreciate time beyond that of one or two generations, much less hundreds, thousands, millions and billions of years. [Read More]

Geoscience and Petroleum Careers Activity Source: SEED (SLB Excellence in Educational Development). Adapted with permission. What adventures await you as a student of the Earth sciences? How about a career as a scientist or engineer working for the world’s largest oilfield services company? SLB employees invent, design, engineer, and apply technologies to help customers find and produce oil and gas more efficiently and safely — often in remote and challenging locations. [Read More]

Geothermal Exchange Activity Source: The Geological Society of America Grade Levels: 6-10 Background If you were to dig a few feet into the ground, you would find that the temperature remains relatively constant, even on the hottest and coldest days of the year. People have learned how to harness the heat underground— called geothermal energy— to heat and cool homes. In this activity, you will model a geothermal exchange system to show how heat can be transferred to help control the temperature in buildings and homes. [Read More]

Geothermal Features in National Parks Activity Source: National Park Service Grade Levels: 4-9 Background Geothermal features are formed by heat from beneath the Earth’s surface, creating amazing sights like geysers, hot springs, volcanoes, and tar pits. Many of these features are now in protected areas designated as National Parks, allowing people to experience them in their natural state. These areas also help scientists study Earth’s processes, while conserving habitats for the unique ecosystems supported by geothermal features and promoting environmental education. [Read More]

Getting Creative - Geologic Map Day Learning Activities “America the Beautiful” has inspired patriotism in Americans for generations. But few today realize that the song’s lyrics were originally written in the late 1800s by Katharine Lee Bates as a poem — one that she first called “Pike’s Peak.” Bates herself had been inspired by the grand landscapes she viewed as she crossed the country on a train trip to Colorado Springs, Colorado.

Getting the Oil Out Activity Source: Society of Petroleum Engineers. Adapted with permission. Artificial lifting systems, or pumping units, are used to help pull oil out of reservoir rock and pump it up a well. A down hole pump in the well is connected to the pumping unit by steel rods, which are screwed together. The pump is activated from the up and down movement of the pumping unit on the surface. [Read More]

GIS and Careers Activity Source: ESRI. Adapted with permission. Geographic information systems (GIS) are mapping and analysis tools that people use in all walks of life. GIS is problem-solving technology, for careers in research, policy-making, and production — in government agencies, non-profit groups, and for-profit companies, from global to local levels. Whatever the sphere — atmosphere, hydrosphere, cryosphere, lithosphere, or biosphere — there are little challenges and major dilemmas that can be addressed only by examining the patterns of where things are, the traits of things here versus things over there, and how things relate to each other. [Read More]

Glacier Slide Activity Source: National Park Service Objective You will be able to describe how a glacier carves an area and label the characteristics formed by the glacier’s movement. Background There are many glaciers all over Alaska. Flying into Lake Clark National Park and Preserve through Lake Clark Pass, you will see many glaciers. These glaciers were growing during the last Ice Age. Now many are retreating because Alaska is getting warmer. [Read More]

Global Change: Where Land, Air and Water Meet Activity Source: USGS Global Change Education Objective 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. [Read More]
