Massive tectonic forces have shaped the Earth for billions of years. These forces are continuous and have the power to create and destroy. In this episode, experts examine the movements of the Australian and Pacific tectonic plates and the resulting landscape. Part of the "Voyage of the Continents" series.

Geologists discuss the tectonic forces that have formed the African continent. Evidence suggests that Africa was once separated from Eurasia by an ancient ocean. Once this ocean disappeared, the continents of Europe and Asia collided. Tectonic forces continue to shape the continent, and some experts believe Africa is being torn apart by these forces. Part of the "Voyage of the Continents" series.
Over the many billions of years of the Earth's history, the planet has never stopped changing shape. Massive tectonic forces have sculpted and resculpted the world in a never-ending process. This episode chronicles the Himalayas, investigates how Siberia joined other land masses, and discusses tectonic activity that impacts Japan and Indonesia. Part of the "Voyage of the Continents" series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on earthquakes and the roll tectonic forces play in their occurrences along fault lines. Part of the Science Video Vocab series.
Hawaii is a state in motion, formed by magma-spewing volcanoes that turn into basalt. The native population of Hawaii considers hot lava an instrument of creation even if it destroys everything in its path. Viewers trace the ever-changing landscape of the Hawaiian Islands due to the active tectonic forces of the region.
North America is continually reinventing itself. Experts discuss the various geographic landforms of the continent. They also touch on the active tectonic forces of the San Andreas Fault and the potentially hazardous dormant volcano in Yellowstone National Park. Part of the "Voyage of the Continents" series.
As shown on the History Channel. From Alaska to New Mexico, the Rockies are one of the great mountain belts of the world--caused by tectonic forces of the Pacific Plate pushing against the North American continent. They have formed as the earth's continental crust has been shortened under pressure, by around one inch a year. What's more, they are still rising and they are still young in geologic terms: when the dinosaurs roamed the Earth they had not even started to form.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The three friends believe they have arrived to planet Earth. They soon realize this is not home. The land breaks and splits when they step on it. Maqui tells them that on Earth, years ago, the same thing happened. She explains that continents are panels that float and move. The three friends learn about tectonic forces.
Volcanoes and earthquakes! Geysers and boiling mud! Natural forces like these have been working for millions of years, changing the surface of the earth. Examines the layers of earth, a history of continental drift, plate tectonics, and other phenomena at work on our planet.
Geologists discuss the three tectonic collisions that created Europe. These forces continue to alter the continent's landscape. This episode examines the evidence of these changes found in Iceland and the Mediterranean Sea. Part of the "Voyage of the Continents" series.
Through descriptions of actual volcanic and earthquake occurrences, students will discover how these dynamic forces affect the world. This video discusses the nature and causes of earthquakes and volcanoes. Other topics covered include molten rock, magma, lava, cinder cone, shield volcano, composite volcano, caldera, Ring of Fire, seismic waves, seismograph, and Richter scale.
Students will explore how the discoveries of specific fossils, the geographic fit of the continents, ocean floor magnetic fields, young ocean rocks, and seafloor spreading provide evidence to support the theory of plate tectonics. Footage from Iceland helps illustrate the power of tectonic movement. Other topics covered include continental drift, Pangaea, tectonic plates, plate boundaries, mountain building, folding, faulting, and landforms.
The geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental drift, mid-ocean ridge, plate boundaries, subduction, convergent boundary, and divergent boundary.
Through observation and experimentation, students will learn properties of forces, Newton’s Laws of Motion, and how pressure affects the world. Real world examples encourage students to explore their surroundings and to discover the impact forces have on everyday life. Part of the Real World Science series.
An early exploration (2015) into how to make a sim accessible has taken place for Forces and Motion Basics. It has working keyboard navigation and auditory descriptions for the 'Net Force' screen when the screen reader is in 'Forms' mode. We are working on updating the content so that it can be read by the screen reader in any mode. Notes for the main interaction: Press 'Enter' or 'Spacebar' to enter a group of pullers. Once in the group, use 'Arrow' keys to choose which puller you wish to select. Press 'Enter' or 'Spacebar' to select puller and move to knot selection. Use 'Arrow' keys to choose between different knots. Press 'Escape' to leave a group of pullers or knots, 'Tab' to leave group and go to next element. This prototype has been tested with NVDA and Firefox.

Students explore the characteristics of fluids. Some topics they study include pressure and its impact on the behavior of fluids, Bernoulli’s and Pascal’s principles, and density and its effect on buoyancy. Additional concepts and terminology discussed include: hydraulic devices, particles, differences in pressure, air pressure, and buoyant force.
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
Patients who have suffered devastating facial injuries sometimes go to great lengths to hide themselves from public view. At the University of Illinois at Urbana-Champaign, civil and mechanical engineer Glaucio Paulino saw the possibilities of combining engineering and medical skills to tackle the complex challenge of facial reconstruction. Part of the National Science Foundation Series “Science Nation.”
Plate tectonics describes the large-scale motion of large and small plates of the earth's lithosphere. As the plates slide past one another, they create friction and heat. The tension caused by the friction of heat is released either through earthquakes or volcanoes. Part of the "Earth Science" series.
