What does it take to get a sailboat moving in the water? With the help of some of the Bay Area’s top aerospace engineers, students learn that sailboats don’t simply rely on wind to push them forward but that there are other invisible forces that are fundamental to the process. In fact, the physical elements that make a sailboat sail are the same ones that make an airplane fly.

What is light? How does it operate? What are its properties? Why is it so important to the foundations of our physical world? Examines the nature of light and how it's harnessed in our lives. Explains the basic properties of light and the wave model. Also, discusses the concepts of wavelength, frequency, speed, reflection, refraction, total internal reflection, and dispersion. Explains the EMR spectrum, the color of objects, and the addition and subtraction of colors.
Anything that takes up space or has mass is matter. Under certain conditions matter can be a solid, liquid, gas or plasma. Different states of matter can be combined in suspensions, and solutions and mixtures can be taken apart. Exploring the physical and chemical properties of matter provides insight into nature and a glimpse at how scientists and engineers use this knowledge to shape our world.
As scientists discovered more and more chemical elements, they began developing systems to organize the elements by their chemical properties, leading to the modern periodic table. Through its organization, the periodic table makes clear the underlying chemical and physical trends among the elements. The periodic table is being continually updated even today as scientists strive to create new elements in laboratories. Part of the series Chemistry: Challenges And Solutions.
Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.
The speed of light is constant in a vacuum, but what about in the everyday world? Examines the behavior of light as it passes through physical substances in a collection of 23 computer-animated video shorts. Outlines Ptolemy's Law of Refraction and the concept of angle of incidence by examining light's motion through air, water, glass, and other media. Explores Snell's Law by highlighting the importance of a refractive index along with displacement, deviation, dispersion, and the role of refraction in fiber optics. Studies lens types including biconvex, convex meniscus, plano-convex, and concave models, in addition to telescopes, magnifying glasses, and the human eye.
Ever wonder what is going on in the mind of a teenager, especially one who is stressed out? UCLA Psychologist Adriana Galvan is on a quest to find out. With support from the National Science Foundation, she’s investigating the effects of daily stress on a teen’s cognition and brain function. She is monitoring the daily stress of teens by having them carry a personal digital device that provides daily measures of stress over two weeks. She is also scanning their brains and measuring their stress hormone levels. By taking this multi-method approach, Galvan is learning how daily stress influences cognitive neurodevelopment in teens.
At the twilight of an active life, Anna is now bedridden due to a serious fall. What makes the elderly--even those who are in full possession of their mental and physical faculties--more prone to falling than younger people? As this program demonstrates, the answer lies not in the body or the brain alone, but in their interconnection. Exploring Anna's past dreams of becoming a ballerina, the film shows how complex physical motion, such as dancing or even typing, requires sophisticated coordination between the body's neural, muscular, and skeletal systems. How aging affects such coordination and how new artificial limb technology enables movement are running themes in the program.
