Students will learn how light is measured. Visual diagrams and hands-on experiments help students understand how light works. Important terminology includes wave, electromagnetic spectrum, wavelength, energy, reflection, lens, and prism.

An elementary class prepares for a visit from the Shadow Players, a group who use light, shadow, and color to tell a story. The class learns about sources of light, shadows, and silhouettes. They experiment with transparent, opaque, and translucent objects to see what lets light through. Using a prism, they discover the colors in light. Review at the end.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

What is light? What are some of the ways people use light? In this program, students develop a basic understanding of light and its uses. The fundamental characteristics of light are highlighted. Concepts and terminology discussed include: night, day, solar energy, and reflect.
Using real-world demonstrations and colorful graphics, students explore how light travels and how different mediums can affect light, resulting in reflection, refraction, and absorption. The color spectrum is also discussed through the use of prisms and paints. Part of the "Real World Science" series.
Olli cannot understand why a light is turned off when it is not needed, since it is so easy to flick the switch. Thanks to Suzie, the children get to meet "Power," who can indeed create ample electricity. They also learn a lesson about conservation and natural resources. Part of the "My Little Planet" series.
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.
Part of the animated "Johan, the Young Scientist" series. Johan travels to ScienScape one evening because of a power outage at his house. There he learns that there are only two sources of light-natural and artificial lights. Professor Hoo then guides him, Ani, and Moki on their night out to find the brightest source of light that is also completely free.
Millions of years ago, a group of bacteria, the cyanobacteria, developed a new way to harness energy from the sun. This new development had important consequences for the evolution of both the atmosphere and the diversity of life on Earth.
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.
Invisible ultra-violet light energy is finding its way into an increasing variety of high-tech applications, such as disinfecting water of hazardous micro-organisms and in the development of paint that dries in seconds. The highly competitive field of computer chip lithography also has chemists and physicists working with ultra-violet light technology. New light technologies are being used to manufacture semiconductors, lenses, and many other technological components.
In this episode, Joel Greene explores the Lighting Resources Facility in Texas, where they collect old light bulbs. They dump them all into an incredible machine that breaks them apart, safely collects the mercury, and cleans the remaining glass. Lastly, Joel follows the crushed light bulb remnants and watches the process of mixing the recycled light bulbs in with recycled glass to create gorgeous counter tops and flooring. Part of the Curiosity Quest Series.
What makes a glow stick glow? And why doesn't it heat up from the light? The answer lies in the processes taking place during chemiluminescence.
Using light as a probe, scientists found innovative ways to make inferences about the inner structure of the atom. In this unit, scientists discuss the change from believing the atom was a single indivisible particle to later understanding the atom is composed of subatomic parts. This new picture of matter lead to the development of the quantum model of the atom, as well as ways to identify traces of chemical elements, whether on earth, in the sun, or in a distant galaxy. Part of the series Chemistry: Challenges And Solutions.
E=MC². Who really understands what lies behind Albert Einstein's famous formula? Follows the development of his scientific ideas with great cinematic style. The documentary deftly combines an appreciation of Einstein's scientific accomplishments, his trials and tribulations in gaining recognition, and his relationships both personal and professional.
Pinky and Petunia discuss light and electron microscopes. They also offer helpful hints on how to use a light microscope. Part of "The Amoeba Sisters" series.
The residents of Block Island fight to save a sea side lighthouse from beach erosion. They join together and hire a team of brothers to move the lighthouse back from the cliffs. The 2,000 ton structure is moved 300 feet in an effort to save it from the ongoing erosion of the bluffs along the coast of Rhode Island.
Not only can lightning strike twice, but it can also strike the ocean. Individuals must take certain safety measures when surrounded by water during a storm. Part of the "NOAA Ocean Today" series.
Qualcomm Thinkabit Lab engineer Saura Naderi teaches students how to make an LED light up and blink. Naderi demonstrates the basics of programming an Arduino board, as well as introduces coding and engineering vocabulary.
Demonstrates techniques for using a student microscope to achieve spectacular images. Emphasizes correct lighting procedures and the techniques required for viewing living cells.
