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.

Nano expert Oliver Brand from Georgia Tech University discusses the difference between nanoscale and atomic scale. Part of the “Ask a Scientist” series.
Observe changes to electrostatic force as you play with the distance between charges and charge amounts at both macro and atomic scales.

Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.
There’s no shortage of ideas about how to use nanotechnology, but one of the major hurdles is how to manufacture some of the new products on a large scale. With support from the National Science Foundation (NSF), UMass Amherst chemical engineer Jim Watkins and his team are working to make nanotechnology more practical for industrial scale manufacturing. Part of the National Science Foundation Series “Science Nation.”
Solar power is defined as the energy produced by converting sunlight into heat or electricity. It is one of the most abundant and affordable sources of energy available. However, it is difficult to harness (and even impractical) in some parts of the world, so it is important to explore the process of converting sunlight to power. Shows three primary ways to produce solar power on a large scale: solar power–generating plants, photovoltaic cells, and solar thermal heaters.
In recent years, the number and scale of wildfires in the U.S. has risen, threatening cities and forests and forcing large-scale evacuations. NSF is supporting the WIFIRE initiative, led jointly by UC San Diego and the University of Maryland, to better monitor, predict, and mitigate wildfires in the future. Part of the National Science Foundation Series “Science Nation.”
Imagine robots no bigger than a fingertip scrambling through the rubble of a disaster site to search for victims or to assess damage. That’s the vision of engineer Sarah Bergbreiter and her research team at the University of Maryland. With support from the National Science Foundation (NSF), they’re building micro-robots to create legs that will ultimately allow a millimeter-scale robot to traverse rough terrain at high speeds. Part of the National Science Foundation Series “Science Nation.”
In this episode, host Emily Graslie discusses the pangolin or "scaly anteater." They are typically found in Africa and covered in an armor to protect them from predators. Part of "The Brain Scoop" series.
There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies. Part of the National Science Foundation Series “Science Nation.”
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Cyclops crashes into the bottom of the pond and discovers an ooze populated by bacteria. After gathering some, the Micronauts begin to investigate the chemical method the bacteria uses to decompose organic material. In the end, the bacterial also helps the crew escape the bottom of the pond so they can continue to explore. Part 5 of the Microscopic Monsters Series.
Covers the concept of ratios and proportions, the correct way to express and write ratios and proportions, ratios and proportions in their simplest form, and comparing ratios and proportions. Provides real-life situations in which ratios and proportions would be applied, such as mixing paint, reading and interpreting map scales, and calculating map distances.
In Miki, Japan, a six-story wooden model condominium was shaken by the equivalent of a 7.5 magnitude earthquake. The test was said to be the largest simulated earthquake ever attempted with a wooden structure. The full-scale building sat on a metal shake table that rocked it violently back and forth. The table, designed to hold up to 2.5 million pounds, reproduced forces based on those recorded during the 1994 earthquake in Northridge, California. But, it was scaled up by 180 percent to simulate an earthquake so violent it would only occur an average of once every 2,500 years. Part of the "Science Nation" series.
How does eye color work? Get ready for a long look deep into the genetics and physics of eye color. Part of the "It's Okay to Be Smart" series.
Anita Kalathil shows some of the latest chemistry projects taking place at Proctor & Gamble and what her typical day is like inside and outside the lab. Find out what it’s like to be a chemical engineer.
Students investigate the wide array of fish found on the planet. Concepts and terminology include saltwater, freshwater, cold-blooded, fins, backbone, eggs, scales, and gills.
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 the term scalars. Part of the Science Video Vocab Series.
Students learn the unique features of reptiles by viewing footage of snakes, lizards, and turtles in their natural habitats. Concepts and terminology include cold-blooded, scales, shell, and eggs.
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 the steps of making scientifically sound observations. Part of the Science Video Vocab series.
It’s called a wavemaker, and its 300 feet long and 12 feet wide. With support from the National Science Foundation, this huge new tool, the largest of its type in the United States, is helping scientists perform large scale studies on the impact of both hurricane and tsunami waves.
