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.

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.

This simulation from the National Center for Atmospheric Research portrays annual patterns in water vapor and precipitation across the globe, illustrating general circulation patterns as well as seasonal and regional variation.

In this interactive activity adapted from the University of Utah's ASPIRE Lab, learn how to measure wavelengths and see how wavelength affects the color of the light that we see.

A selection of children's books is provided to help students learn about the greenhouse effect and ways humans impact the environment. The book list complements lessons and activities focused on the theme of the free, online magazine Beyond Weather and the Water Cycle. The magazine integrates science and literacy learning for students in grades K-5.

The 11 books selected for inclusion in the issue of Beyond Weather and the Water Cycle devoted to climate studies range from easy readers to biographies. Each book is briefly described; all were reviewed for accuracy and appropriate reading levels for students in grades K-5. Several books deal with careers in meteorology.

Do you eat like a horse? Or more like a bird? As you might expect, different animals eat different things. Some animals specialize in eating one particularly rich food source, while others eat whatever they can find. This video segment samples the diversity of feeding habits among some of the world's creatures.
Recommended for: Grades K-5

There's no need to don a space suit if you want to experience weightlessness. In this video segment adapted from ZOOM, two members of the cast drop a cup of water with holes in it to demonstrate how free fall can create a momentary condition of "weightlessness".
Recommended for: Grades K-8

This video segment, adapted fromThinking Big, Building Small, demonstrates each part of the engineering design process, which is fundamental to any successful project. Though it does this in the context of building skyscrapers, the process is applicable to any sort of project, including constructing schools, building bridges, and even manufacturing sneakers. Students will recognize the value of going through its steps sequentially when constructing scale models. Recommended for: Grades 3-12

This video/animation shows that a molecule of water is made up of oxygen and hydrogen atoms. When oxygen and hydrogen atoms exist alone, their properties are different from the properties they have when they are chemically combined to form a water molecule.

This article points out that there is no one official definition for the Arctic. Then the author identifies definitions ranging from geography to climate to culture and more. Maps and other visuals illustrate the definitions. The author suggests that defining the Arctic can be an example for K-Grade 5 students of the nature and challenges of classification systems. The article appears in the free, online magazine Beyond Penguins and Polar Bears.

In this animated video segment adapted from NASA, astronomer Doris Daou explains how the forces of speed and gravity keep the Moon in a constant orbit around Earth.

In this video adapted from Texas Parks and Wildlife Department, see how volunteers care for sick or injured animals. Also learn why human interaction is not always the best solution.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.
