In this adapted video segment, ZOOM guest Laura shows us some of the natural features of Yellowstone National Park, including geysers, hot springs, fumaroles, and mud pots, as well as some of the wildlife.

Students explore the motion of molecules and the ways in which they interact.

This interactive resource adapted from the National Park Service illustrates the difference between explosive and effusive volcanic eruptions as well as the hazards that can result, including lahars, tsunamis, and lava flows.

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.

This activity provides students with a first look at water tension and its role in the life of a water strider.

This activity provides students with a first look at water tension and its role in the life of a water strider.

Website from Washington State University answers questions kids have about science, mechanics and engineering in an easy to understand format. In this letter, Dr. Universe answers questions about how the family car works.

This activity investigates water when it freezes and how other solid items sink or float in water.

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 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.

The students will use investigation and data collection to investigate the three states of matter. They will draw conclusions about the physical properties by answering questions.

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.

This is a short lesson (including hands on activities) on polymers and plastics to expand our study of physical/chemical properties and changes.
