Part of the "A 3-D Demonstration" series. Explores basic electricity as it was perceived by Benjamin Franklin and other early theorists as well as the principles of positive and negative charge, conduction and induction, atoms and electrons, and elementary charge. Relates Coulomb's Law in detail, including the torsion balance experiment, that led to a breakthrough in scientific theory related to electricity.

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.
There's been a lot of talk and research interest around the possibility of resurrecting certain groups of organisms from extinction. In this episode, host Emily Graslie discusses this possibility with a focus on the woolly mammoth and the mastodon. Part of "The Brain Scoop" series.
Aeronautics is the science of flight as well as the theory and practice of aircraft navigation. Any machine that flies through the air falls into the field of aeronautics. This includes helicopters, airplanes, as well as space vehicles such as the SpaceX Dragon and the retired NASA space shuttles. Aerodynamics is a branch of physical science which deals with the motion of air and the way that it interacts with objects in motion.
Find out how Albert Einstein used the totality phase of the 1919 solar eclipse to prove his theory of relativity, which predicts that large objects bend “space-time” towards themselves.
Dr. David Kimbro and Dr. Randall Hughes investigate a new idea: can crabs hear? They design an experiment to test their new theory and explore the effects it may have on the crabs. Part of the series "In The Grass, On The Reef."
Part of the "A 3-D Demonstration" series. Presents both the theory of electric circuits and basic practical methods of managing circuits safely. Investigates the benefits and dangers of ground circuits together with safety devices, such as fuses and ground fault interrupters. Introduces the concept of electric resistance. Specific modules include Completing a Circuit, Fuses, Circuit Breakers, Ground Circuits, Ground Faults, Ground Fault Interrupters, Resistance, and Electrical Resistance. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Is light composed of waves or particles? Explores the wave model of light from its earliest roots to our modern understanding of electromagnetism in 17 computer-animated video modules. Expresses Empedocles' belief that light streams from the eye, Aristotle's conception of light as a disturbance in ether, and Euclid's mathematical, ray-centered paradigms. Presents the Cartesian sine wave model, Huygens' principle of bending wave fronts, the electromagnetic spectrum, and aspects of particle theory. Provides an overview of diffraction, interference, polarization, and dispersion. Also explains Young's double-slit experiment.
A mysterious killer is lurking in the steely waters off the east coast of Canada. Scientists are baffled by all the corpses on the beach. The seals bear bizarre spiral wounds which have led to one theory that one of the most elusive of all sharks is responsible, the Greenland shark. Scientists from the Canadian Shark Research Laboratory and the Apex Predator Program in the United States will try to solve the puzzle of the dead seals once and for all. Please note: this title shows images of animal corpses and shark attacks on seals.
This animated short tells the story of Alfred Wegener, a German astronomer and atmospheric scientist, who came up with the idea that continents once formed a single landmass and had drifted apart. Continental drift explained why continents' shapes fit together like pieces of a puzzle and why distant continents had the same fossils. During Wegener’s time, the idea was met with hostility but after his death a large body of evidence showed that continents do indeed move. Today the theory of plate tectonics is a fundamental principle in geology.
Harvard economist Alvin Roth is a matchmaker but he’s not finding love – he’s finding kidneys. With support from the National Science Foundation, he and his team have developed a suite of computer programs that match living kidney donors with recipients. Why is an economist organizing kidney transplants? It turns out that an understanding of game theory and market dynamics is key to optimizing pairings. It's all about streamlining complicated matches using the science of the marketplace. Their matching software is the engine that has helped transplant centers in 30 states so far.

Teachers often say to students, “Put your thinking caps on,” and one day, students might just do that for real. Vanderbilt University psychologist Geoffrey Woodman says that’s because scientists are being equipped with more and more tools they can use to better understand the brain, and now, they can even eavesdrop on individual neurons. Initial support from the National Science Foundation (NSF) allowed Woodman and his team at the Vanderbilt University Visual Cognitive Neuroscience Laboratory to study memory and perception. Then, the researchers tested their theory that electrical stimulation of the medial frontal cortex can boost learning and improve decision-making.

This project envisions a future where 3-D robotic systems can be produced and designed using 2-D desktop technology fabrication methods. If this feat is achieved, it would be possible for the average person to design, customize, and print a specialized robot in a matter of hours. This new project would completely automate the process, from sketches on-demand, anywhere, and with the skill of a team of professional engineers, leading to potential transformations in advanced manufacturing. The Computer Science and Artificial Intelligence Laboratory, known as CSAIL is focused on conducting groundbreaking research in artificial intelligence, computer systems, and the theory of computation, while also tackling pressing societal challenges such as education, health care, manufacturing and transportation.

After Charles Darwin first visited the island archipelago of Galapagos in 1839, it took him another twenty years to decipher that the scene he'd witnessed was the most perfectly preserved biodiversity on the planet. His theory of evolution, published 150 years ago, pulled back the curtain on a debate that had been simmering for years, and still percolates. Today Darwin would be surprised by the tourist mecca Galapagos has become--200,000 visitors a year, 40,000 permanent residents. The impact on the most unique collection of endemic wildlife in the world has been heavy. Too many people are bringing too many of their ways (and invasive species) from the outside world that are threatening the future of this one-of-a-kind place. What would Darwin think of how Galapagos has evolved in the twenty-first century?
It’s widely believed that the younger one is, the easier it will be for one to learn a new language, and new research is finding that holds true for sign language as well. University of California, San Diego (UCSD), psychologist Rain Bosworth says that by five months old, babies are universal language sponges, attracted to language in their environment, and this includes sign language. With support from the National Science Foundation, Bosworth and her colleagues at the Infant Vision Lab (IVL) have been putting that theory to the test, investigating how deafness affects perception and cognition in babies, and the impact of early exposure to sign language. The team includes Karen Dobkins, director of IVL, So-One Hwang, of UCSD’s Center for Research in Language, and student researchers Adam Stone of Gallaudet University and Hector Borges of UCSD. Part of the National Science Foundation Series “Science Nation.”
