This interactive resource adapted from the National Park Service illustrates the variety of landforms and features created by volcanoes. Featured are calderas, craters, fumaroles and other geothermal features, igneous rocks, lava flows, lava tubes, and maars.

This video segment adapted from Last Oasis explores the use of new dams as a way to provide or store water. In the 1990s, the city of Denver was looking for a new source of water for its growing population, and its plan to build a new dam suddenly became highly controversial.

This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how water moves through Earth's four systems. The activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons.

In this video from Nature, learn about the erosive action of water on the Hawaiian landscape and human efforts to limit it.

In this video segment adapted from NOVA, learn about an experiment investigating whether liquid water on Earth could have resulted from a massive planetary impact billions of years ago.

In this video segment adapted from ZOOM, visit a water treatment plant and learn how water from a local reservoir is turned into drinking water.

In this lesson, students utilize case studies to learn about the ways climate change is currently impacting people and other living things around the world.

In this video from the Science and Technology Chat series, learn about astrobiology, an interdisciplinary field that uses biology, astronomy, and geology to study the origins of life on Earth and to search for possible life on other planets.

In this video from WOSU Columbus, learn about wetlands, their different varieties, and why we should care about them.

In this lesson, students explore reasons why temperatures in particular Colorado cities are rising.

This lesson explores climate data at local, national, and global levels to determine that temperatures are changing all over the world, and that there are certain locations where temperatures are warming faster than the global average.

This lesson introduces why certain cities in Colorado are getting hotter using a video by the Denver Post that describes the pattern.

In this video segment from Planet H20: Water World, experts and teens inside and outside the Great Lakes watershed provide different perspectives on sharing the water from one of the largest bodies of fresh water in the world.

During this lesson, students explore the increase in summer temperatures and describe the pattern as it relates to Colorado using a video by the Denver Post.

This lesson has students investigate how albedo is contributing to temperature increasing in some places, like cities, are increasing at faster rates than elsewhere.

This lesson has students explore what land use changes are happening and how changes in surface color affects temperatures in cities.

In this video segment adapted from Haskell Indian Nations University, meet Elders who describe dramatic changes that they have witnessed in their local environments.
