Discusses an activity in which computers with color monitors can be used to demonstrate light blending with relative ease. (MKR)

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

This educator's guide from discusses optics, light, color and their uses. Activities include: (1) "Reflection of Light with a Plane (Flat) Mirror--Trace a Star"; (2) "Reflection of Light with Two Plane Mirrors--Double Mirrors Placed at a 90-Degree Angle"; (3) "Reflection of Light with Two Plane Mirrors--Double Mirrors Placed at a Number of…

Describes a convenient method of displaying color effects (colors of the blue sky, white clouds, and red sunsets) of Rayleigh and Mie scattering. (ZWH)

This book contains scaled-down versions of Exploratorium exhibits that teachers can make using common, inexpensive, easily available materials. Each topic begins with a drawing of the original full-sized exhibit on the museum floor, a photograph of the scaled-down version which contains an introduction to the exhibit, a list of materials needed…

Tested demonstrations on (a) color development through the formation of subtractive primary dyes and (b) fluidity of gases are presented. (CP)

Presents the Night Spectra Quest, a pocket-sized chart that identifies in color the spectra of all the common night lights and has an integrally mounted, holographic diffraction grating to look through. (JRH)

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

Two different methods of measuring the temperature of an incandescent lamp at various voltage levels are described. By observing the color produced at a particular voltage levels, the lamp's color as a function of temperature can be determined. Needed equipment include a variac, a voltmeter, and an ammeter. (KR)

Presents several demonstrations in spectroscopy. (RH)

Explains a demonstration that shows the additive nature of light using three overhead projectors. (GA)

Several activities related to color are discussed. These include placing different colors on a disk which, while spinning, appears to be white. Also discusses complementary and primary colors. (JN)

Science and art have much in common. Artists as well as scientists carefully observe and communicate their subjects. Throughout time, artists have been involved in experimentation, an important scientific method which can lead to new discoveries. Both scientific developments and the ongoing history of art are cumulative. This learning packet is an…

Most people certainly take light for granted. But understanding the basic nature of light can open up a whole new world! All about Light takes kids on a fun journey to answer questions like: "Why does light shine through some things and not others?" and "Why can we see our reflections in water, but not in a rock?" Students learn how light travels…

Why does light behave the way it does? How does it travel from its source to the objects it illuminates and then to human eyes? Students will learn about waves, including the concepts of reflection, absorption, refraction and how light is related to the colors that can be seen. With a hands-on activity and real-life examples, these concepts are…
