In this video segment adapted from Navajo Technical College, meet two members of the Navajo Nation, one Elder and one scientist, as they share their observations about how precipitation has changed since they were children.

In this video segment adapted from NOVA scienceNOW, MIT engineer Dava Newman is working to replace today's bulky, inflated space suits with a radical, sleek design that may one day allow astronauts to walk easily on Mars.

This video segment produced for Teachers' Domain features a time-lapse video of clouds forming, changing, and moving across the sky.

In this video segment produced for Teachers' Domain, observe different types of precipitation, including rain, hail, and snow. [1:00]

Learn how snowfall happening later in the year than usual is impacting cultural practices in this video segment about climate change adapted from the College of Menominee Nation.

In this video segment adapted from the College of Menominee Nation, tribal members observe lower water levels in lakes and streams and call for global, collaborative solutions to address climate change.

Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how filters, evaporation and/or condensation can be components of engineering desalination processes. They learn how processes can be viewed as systems, with unique objects, inputs, components and outputs, and sketch their own system diagrams to describe their own desalination plant designs.

This video segment adapted from NOVA follows the clean-up effort after the 1989 Exxon Valdez oil spill off the coast of Alaska. Also featured is a marsh where an oil spill occurred 20 years earlier; analysis suggests that environmental damage may last for decades.

Looking at models and maps, students explore different pathways and consequences of pollutant transport via the weather and water cycles. In an associated literacy activity, students develop skills of observation, recording and reporting as they follow the weather forecast and produce their own weather report for the class.

For students that have already been introduced to the water cycle this lesson is intended as a logical follow-up. Students will learn about human impacts on the water cycle that create a pathway for pollutants beginning with urban development and joining the natural water cycle as surface runoff. The extent of surface runoff in an area depends on the permeability of the materials in the ground. Permeability is the degree to which water or other liquids are able to flow through a material. Different substances such as soil, gravel, sand, and asphalt have varying levels of permeability. In this lesson, along with the associated activities, students will learn about permeability and compare the permeability of several different materials for the purpose of engineering landscape drainage systems.

Students are introduced to the fabulous planet on which they live. Even though we spend our entire lives on Earth, we still do not always understand how it fits into the rest of the solar system. Students learn about the Earth's position in the solar system and what makes it unique. They learn how engineers study human interactions with the Earth and design technologies and systems to monitor, use and care for our planet's resources wisely to preserve life on Earth.

The lesson introduces students to the steps of the water cycle and rivers. They think about the effects of communities, sidewalks and roads on the natural flow of rainwater. Students also learn about the role of engineering in community planning and protecting our natural resources.

KIDS Clubhouse Adventures kids visit The National Mississippi River Museum and Aquarium to read and discover more about water, the water cycle and how water can be used to generate energy. [1:36]

This article explains how the ice and snow of the polar regions fit in the global water cycle and includes links to professional development resources.

Students will learn about per- and poly-fluoroalkyl substances (PFAS) and synthesize their learning into curious questions, as well as evidence-based responses, about the chemical that is threatening the Great Lakes.

Students will become familiar with two major river projects, one in the Chicago River and the other on the Cuyahoga River, and the restoration efforts involved with each.

This video segment from Nature takes viewers to a road race in Death Valley.

This animation adapted from NASA shows the orbital paths of spacecraft in NASA's Earth Observing Fleet that are a source of wide-scale, primary research about Earth.
