Earth’s Hydrologic Cycle Activity Source: Adapted from the Ocean Institute Curriculum Series Overview 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. Concepts The hydrologic cycle is the continual movement of water from one place to another and from one state of matter to another. [Read More]

Energy Efficiency Activity Source: Schlumberger Excellence in Educational Development. Adapted with permission. In Swords into Plowshares: At Home in a Missile Silo, Tony Crossley says of his underground home: “The winters are bitterly cold, the summers feature spectacular afternoon thunderstorms and occasional tornadoes, and throughout the year we get days when the wind is very strong. Underground it’s always quiet and peaceful, and no matter how cold it gets outside, the interior never freezes, even though we don’t have any heating yet. [Read More]

Exploring Climate Change with GIS Activity Source: ESRI. Adapted with permission. Earth’s climate is a product of and is affected by many things—and it’s changing. Long-term and short-term processes, such as plate tectonics and volcanism, contribute to climate. Likewise, human influences, such as rising CO2 levels from fossil fuel burning and deforestation, play active roles. The expression of climate change is seen in a variety of forms: Erratic weather patterns and rising sea levels are among the most discussed. [Read More]

Exploring Permafrost in the Arctic Activity Source: Written by AGI with the Natural Resources Conservation Service Permafrost, frozen ground lasting at least two years, is found in Earth’s coldest regions: the Arctic, boreal zones, Antarctica, and high-altitude areas. It profoundly impacts the plant, animal, and human communities in these regions. Permafrost underlies 15% of the northern hemisphere’s exposed land. It is prevalent across the Arctic and extends into areas like Alaska, Canada, Greenland, Russia, and the Tibetan Plateau. [Read More]

Exploring the Age of the Seafloor Activity Source: Written by AGI based on lessons by the International Ocean Discovery Program The Earth’s surface is made up of tectonic plates that fit together something like puzzle pieces, forming fault lines where they meet. There are seven major plates and some smaller ones. These plates move apart at divergent boundaries and collide at convergent boundaries. At transform boundaries, the plates slide past each other.

Exploring Watersheds in North America Activity Source: Written by AGI for ESW 2024 Watersheds serve as natural drainage systems, collecting rainfall and channeling it towards a common outlet such as lakes, rivers, or oceans. The health of watersheds directly impacts the availability and cleanliness of water for drinking, agriculture, and ecosystems. Additionally, watersheds play a critical role in regulating water cycles, mitigating floods, and replenishing groundwater reserves. Understanding and managing watersheds is essential for sustainable water resource management and ecosystem conservation, ensuring the well-being of both human and natural communities. [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]

Greenhouse in a Beaker Activity Source: Adapted with permission by The NEED Project. Carbon is naturally found in the atmosphere. Carbon dioxide, or CO2, itself is not considered a pollutant. The CO2 being released from burning fossil fuels was part of the atmosphere hundreds of millions of years ago before being captured by plants and sea organisms. Carbon atoms naturally cycle through the biosphere, the atmosphere, the hydrosphere, and the lithosphere in process known as the carbon cycle. [Read More]

Groundwater Movement Activity Source: Adapted from “The High Plains: Land of Extremes” Bureau of Land Management, 1996 Background 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. Groundwater supplies about 38 percent of the water used for agriculture in the United States. [Read More]
