Learn about underwater volcanoes and the discovery of the erupting deep-ocean volcano West Mata. The video provides students with the opportunity to visualize a phenomenon that is too dangerous and too remote to experience. Students view a visualization of the ocean floor as well as footage that cap
The Index of Refraction and Snell’s Law
In this video from the ICT Center, learn about the index of refraction and Snell's law. Review a simple example of refraction, the speed of light in materials and the formula for calculating the index of refraction. Explore a table of the refractive indices of common media and materials used in fiber optics and semiconductors. Finally, examine Snell's law to understand the relationship between incident and refracted angles. This video is available in both English and Spanish audio, along with corresponding closed captions.

Learn about the value of the wetlands ecosystems in this video segment adapted from Texas Parks and Wildlife Department. Wetlands are essential habitats for plants and wildlife and a critical part of the water cycle. Yet they are under threat, largely due to the needs of a growing human population.
In the late 1960s, scientists accidentally discovered gamma-ray bursts — intense flashes of energy that typically last no more than a few minutes and are often as short as a fraction of a second. For decades after the discovery of these powerful bursts, they remained one of the greatest mysteries in
