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.

Ever wonder how a battery works? This segment highlights voltaic cells, their various components and how they operate.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle. Learners can observe the whirling water and then repeat the process by inverting the bottle. Use this activity to talk about surface tension, pressure, gravity, friction, angular momentum, and centripetal force.

In this video segment from TV411, WNBA player Olympia Scott Richardson discusses her techniques for effective time management.

In this podcast, learn about student misconceptions about heat and activities that target them.

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 article describes ways to supplement a science unit on the water cycle with the book Water Dance by Thomas Locker. Ideas for art, writing, poetry, and creative movement are included.

In this issue of the free online magazine, Beyond Penguins and Polar Bears, explore what the polar regions can teach us about the water cycle and the states and changes of matter. Find lesson plans about the many forms of water, ice, and snow found in the polar regions and how to use science notebooks to integrate literacy and science.

This article assembles free resources from the Water, Ice, and Snow issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

This article highlights children's literature about states of matter, phase changes, the water cycle, and glaciers and icebergs for use in the elementary classroom.

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.

Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.

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.

This one-page article by the NRICH team reports on the history of the measuring of weight/mass. It is an attempt to provide material and ideas for lessons that address the disciplines of history and mathematics. Topics covered include weighing by comparison, the need for standard units, and weighing methods in various cultures. Questions and suggestions are provided for further research by students.

This formative assessment item is used to uncover student ideas about solar radiation. Students will decide what they believe the sun provides to Earth. It is aligned to National Science Education Standards. Resources are provided to give additional information, as well as instructional suggestions.

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/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.

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.
