Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.

The Earth has many land formations such as mountains, plateaus, hills, and plains. These formations are created by movement of the earth’s plates, volcanoes, weather, and erosion. Part of the Real World Science series.
Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.

In this video, students will learn about the two major types of weathering: mechanical and chemical. These forces alter the shape and composition of rocks. Students will also explore the different types of soils, soil properties, and soil profiles. Other topics covered include oxidation, soil formation, soil texture, horizons, leaching, subsoil, soil conservation, and groundwater.
This national monument tells the story of the California’s Sierra Nevada Mountain Range. Established in 1911 by presidential proclamation, Devils Postpile National Monument protects and preserves the Devils Postpile formation, the 101-foot high Rainbow Falls, and pristine mountain scenery. The formation is a rare sight in the geologic world and ranks as one of the world's finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry.
Devils Tower is a flat-topped volcanic formation that looms more than 1,200 feet above Wyoming’s eastern plains and the Belle Fourche River. The geologic feature protrudes out of the rolling prairie that surrounds the Black Hills. The site is considered sacred to the Lakota and other tribes that have a connection to the area. Hundreds of parallel cracks make it one of the finest traditional crack climbing areas in North America.
Students explore the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is given to safety and electricity. Concepts and terminology include charge, current, lightning, battery, generator, and wiring.
Bill Nye explains how Jupiter helped spread the building blocks of life and the planet's role in the formation of the solar system. Part of the “Why With Nye” series.
Organic acids, found in common foods, appear as citric acid (lemons), acetic acid (vinegar), and malic acid (apples). Also shows esterification and the formation of an ester.
Surveys soil's formation, composition, properties, types, and movement. Also identifies the five major plant communities: tundra, forests, scrublands, grasslands, and deserts. The connection between soils and vegetation affects where people live.
Host Lisa Van Pay meets researchers who study life in caves. The team explores Snowy River, a bright white crystalline formation found deep within Fort Stanton Cave in New Mexico, finding life and energy in unexpected places.
Chemistry experiments with salts demonstrate the following: neutralization; neutral, alkaline, and acid solutions; preparing zinc sulfide and sodium chloride; and the formation of ammonium chloride.
While it may not always seem possible, Earth is continually changing. Students gain insight into geological processes such as the formation of land, erosion, and volcanic eruptions. Other Earth processes are also investigated.
How can substances, such as water, exist in several dramatically different phases? Easy-to-understand examples illustrate how phase changes occur. Additional concepts and terminology include states of matter, particles, solid, liquid, gas, plasma, melting, freezing, vaporization, boiling, evaporation, condensation, and sublimation.
Hurricanes are one of the most powerful and destructive forces on Earth. How do they form? The formation of a hurricane is complicated, but basically, it depends on 3 factors: warm water, moist air, and converging winds. Part of the "Danger Zone" series.
Drawing upon the American Geological Institute's huge geoscientific archive of information, this segment explores the hydrosphere and the atmosphere. It also covers their formation and components, the water cycle, geological evidence of past climate change, extreme weather, and the future of the fluid spheres. Part of the "Visions of Earth" series.
Experiments feature: (1) halogens as oxidizing agents, (2) bromine reacting with potassium, (3) detecting bromine in compounds, (4) combustion of sulphur and the formation of sulfuric acid, (5) properties of phosphorus, and (6) spontaneous ignition of white phosphorus.
Is there life on other planets? How can it be found? Presents the scientific theory of life's beginning and evolution on earth before considering life within our solar system and beyond. Discusses possible planet formation from stellar dust and technology's place in locating such planets.
Real satellite imagery, as well as simulations, explore how Earth's moon has changed over time. This video looks at how the moon likely formed about 4.5 billion years ago, how impacts from large objects formed craters, and how additional impacts from smaller objects continue to cause cratering.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on what it means for substances to freeze. Part of the Science Video Vocab Series.
