Resource	Grade Level	Media Type
The Beginnings of the Telescope This animated essay from the NOVA Web site examines the design of Galileo's refracting telescope and Sir Isaac Newton's reflecting telescope.	6-12	HTML Document
Diamonds: The Science Behind the Sparkle This illustrated essay from the NOVA Web site explains why the atomic structure of a diamond slows down light and produces a sparkle more brilliant than from any other colorless substance.	6-12	HTML Document
Galileo's Telescope The invention of the telescope helped change our understanding of the universe. This video segment adapted from NOVA looks at Galileo's contribution to this technology.	6-12	QuickTime Video
Geometric Optics This interactive simulation adapted from the University of Colorado's Physics Education Technology project illustrates how lenses refract light to form images. Manipulate the object, screen, lens, and focal length and observe how the image adjusts.	6-12	Flash Interactive
Laser Waterfall In this video from the Encyclopedia of Physics Demonstrations, observe how a laser beam is trapped in a water jet because the light reflects against the surface of the water.	6-12	QuickTime Video
Light Particles Acting Like Waves: The Uncertainty Principle This video segment adapted from A Science Odyssey uses a laser beam to demonstrate how light particles act like waves, illustrating Heisenberg's Uncertainty Principle.	9-12	QuickTime Video
$Observing Refraction of Light$ Observing Refraction of Light This video segment adapted from Shedding Light on Science illustrates how light changes speed, and thus direction, in a process known as refraction.	5-12	QuickTime Video
Primary Colors of Light and Pigments In this interactive activity adapted from Shedding Light on Science, discover the difference between the primary colors of light and the primary colors of pigment—and the connection between the two.	6-12	Flash Interactive
$Refraction of Light Demonstration$ Refraction of Light Demonstration In this interactive activity featuring videos adapted from the Rutgers PAER Group, observe how light bends when it travels through a convex lens, a concave lens, and glass.	5-12	Flash Interactive
Speed of Light This video segment adapted from Shedding Light on Science uses historical illustrations and everyday examples to show that light has a speed and does not travel instantaneously.	5-12	QuickTime Video
