Exploring Low-Temperature Geothermal Energy Activity Source: American Association of Petroleum Geologists Background Geothermal energy harnesses Earth’s internal heat to generate power. Typically, it involves tapping into high-temperature reservoirs of hot water deep beneath Earth’s surface. However, as the demand for clean energy grows, researchers are developing innovative techniques to access common low-temperature geothermal sources found closer to Earth’s surface. New technologies broaden the geographic reach of geothermal energy, making it a more accessible and sustainable energy option. [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]
