Waters of the Earth

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

National Geographic's MapMaker Interactive is a wonderful tool to use when introducing your hydrologists to the water cycle. Show your class Earth's oceans and the movement of water from place to place. Then, using a large colorful...

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

After completing the activity, "Kinesthetic Astronomy: The Meaning of a Year," zoom in on Earth's rotation using the same simulation setup and this outline. Each class member dons a map of the Western Hemisphere and plays the part of...
