In this episode, host Dianna Cowern investigates the biomechanics of butts. What activates one's butt muscles more, running or squatting? How effective are bridges as a workout? How much can individuals change the shape of their bodies with exercise? Dianna and Dr. Rowley conduct various experiments to answer these questions about anatomy and physiology. Part of the "Physics Girl" series.

In this episode, host Joe Hanson discusses the science behind hot air balloons. He also explains the ideal gas law. Part of the "It's Okay to Be Smart" series.
A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. In this episode, host Dianna Cowern leads a discussion on black holes and reviews Stephen Hawking's last paper on black holes. Part of the "Physics Girl" series.
In this episode, host Dianna Cowern asks the question, “What happens to an image when bending a spoon from concave to convex?” Part of the “Physics Girl” series.
Everyday examples and laboratory experiments explain and demonstrate the concept of waves as they relate to physics. Three segments cover the characteristics of transverse and longitudinal waves and the reflection and refraction of waves. Complex physics is made clearer by the lab demonstrations.
Think all squash balls bounce the same? Think again! Two MIT scientists look into what makes things bounce better than others. Ready for some physics? Part of the "Science Out Loud" series.
Presents three key physics concepts about force and motion: constant speed, acceleration, and gravity and falling. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Geophysicist Emilie Hooft describes her work and the important role physics plays in understanding volcanoes. She also reveals how data helps create the images of magma structures beneath volcanoes. Part of the “EarthScope Chronicles” series.
A soccer stadium is perfect to put to test the principals of physics, math, biology and technology. How to generate certain effect by kicking a ball? With what angle are we able to achieve the longest distance? How is a fixture put together for an Argentine soccer tournament?
Grab the Chemistry to play and explore concepts related to friction. Note when using the VoiceOver screen reader with this simulation it is easy to activate VoiceOver's Quick Nav mode while moving the Chemistry book. For the best experience, however, we recommend keeping Quick Nav off.

Are humans the accidental products of an uncaring universe? Or are they the beneficiaries of a cosmic order that was planned beforehand to help them flourish? This documentary explores growing evidence from physics, chemistry, biology, and related fields that our universe was designed for large multi-cellular beings like ourselves. Geneticist and author Michael Denton investigates the special properties of carbon, water, and oxygen that make human life and the life of other organisms possible.
Science laboratories present a whole range of potential hazards to people's health and well-being, and it is critical that both teachers and students are fully aware of their responsibilities to ensure the learning environment is kept safe at all times. Aims at viewers who are not new to science laboratories. Covers a range of safety areas, including general safety in these laboratories and specific areas of potential risk in chemistry, biology, and physics labs.
When it comes to ultrafast lasers, Margaret Murnane’s name is one of the best known for her work in this field of science. Since 1999, she has been a professor at the University of Colorado’s National Science Foundation funded JILA Physics Frontier Center, where she and her husband, Henry Kapteyn, pioneer research in ultrafast x-ray science. Part of the Scientists and Engineers On Sofas Series.
The Atacama large Millimeter/Sub-millimeter Array, or ALMA, is a vast array of radio telescopes and the most powerful observatory of its kind. ALMA is stationed in the Atacama Desert of Chile which is one of the world’s best sites for observational astronomy because of the high altitude, nearly non-existent cloud cover, dry air and lack of light pollution and radio interference due to the small populations. ALMA peers into previously hidden regions of space with unprecedented sharpness and sensitivity.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle shrinks the kids so they can play a game of "frictionless baseball" on page 97 of Dorothy Ann's new physics book. But how will they get back to class when the wind blows the book shut trapping Ms. Frizzle and the class in the closed book?
How did 20th-century physics change long-held notions of light's makeup and behavior? This group of 12 concise computer-animated videos illustrates Einstein's monumental contributions to the study of light. Shows how rudimentary ideas of material wave motion yielded to more advanced concepts of electromagnetic waves by detailing Einstein's conclusions about the speed of light and his conception of time, which-given his findings on mass and energy-proceeds according to variable frames of reference. Conveys relativistic thought experiments through helpful animation, which demonstrate simultaneity, time dilation, length contraction, and relativistic mass.
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons and/or protons). The difference in mass between the products and reactants is manifested as the release of large amounts of energy. This difference in mass arises due to the difference in atomic "binding energy" between the atomic nuclei before and after the reaction. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.

Part of the "A 3-D Demonstration" series. Looks at physics principles behind AC and DC generators. Examines the relationship between a changing magnetic field and the induction of electric current. A hand rule is introduced to predict the generator effect in a linear length of conductor exposed to a changing magnetic field. The behavior of a rotating coil in a magnetic field leads to the practical construction of an AC motor. Introduces split-ring commutator generators, as well as the more common alternator as a means of generating DC electricity. Specific modules include Generating Electricity, Inductors, Generator Left-Hand Rule, Generator Electromotive Rule, AC Generators, and DC Generators. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Longitudinal waves carry energy through air, water, and solids. They compress and expand the medium in the same direction as the energy is transferred.
