Art & Optics: Science and Art Closer Than You Think
Optical technology and the study of light go far back in human culture. Contemporary artists are often quick to adopt new technology, or to absorb its implications. Was it any different then? Why should the use of a tool diminish the value of the art?
Concepts of Light and Color
A set of interactive Java applet tutorials to help you understand how color and light work. Beautifully done. Lots of levers to slide to make changes. From Molecular Expressions.
Here you’ll find pictures, videos, games, educational materials, and more. A fun way to learn all about the “cool” part of the electromagnetic spectrum: infrared light.
Fermilab’s System of Web Pages About Light
Light is great, light is mysterious, light is useful. After all, they say everything started with light. When any revolution has happened in the history of science, light was always there. So it deserves a little attention.
The Light Stuff
Here on Earth the speed of light can change. How? Go to Joe’s Room and see if you can figure it out.
An interactive tour of current research in the materials sciences at Berkeley Lab’s Advanced Light Source. For high school students, this site explains how intense light is used for physics research.

Some fun and interesting things about OPTICS: the science of LIGHT, and one of the most important fields of PHYSICS. by Bruce Irving, Optical Research Associates.
Chemiluminescence – Light without Heat
To do this experiment, you’ll need some light sticks from a sporting goods store or a necklace from a fair. You’ll watch what happens when you put it in hot water and in your refridgerator.. From Home Experiments by Professor Shakhashiri.

Chemistry of Autumn Colors
Formerly green leaves turn to brilliant shades of yellow, orange, and red. These color changes are the result of transformations in leaf pigments.
Do this project to see the hidden colors in a green leaf and predict what color it will be in the fall.
Paper Towel Chromatography
Colors makes color! Separate different colors from a marker.
Why Do Leaves Change Color in the Fall?
Chlorophyll Breaks Down. But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

The Infrared Zoo What do animals look like in the infrared? Actually “see” the differences between warm and cold-blooded animals, and learn how animals use fur, blubber and feathers to insulate themselves.
Build a Pizza Box Solar Oven
The sun is hot enough to bake food. Here’s how to make a simple solar oven that gets hot enough to warm up cookies and other treats, like s’mores. It won’t get really hot, though, so you can’t bake things in it and you won’t burn yourself when playing with it. Be sure to have an adult help you with this!
Language of Color
Feng Shui and Color
Response to color symbolism is a response to color preconception, and it is a predetermined response based on literary and psychological ideas about color itself.

Building a Rainbow
Young students will enjoy just creating online rainbows. More advanced students can take the whole lab course to understand how rainbows obey the rules of calculus.
The Physics of a Rainbow
A most charming example of chromatic dispersion is a rainbow. When white sunlight is intercepted by a drop of water in the atmosphere, some of the light refracts into the drop, reflects from the drop’s inner surface, and then refracts out of the drop. Sunsets & Blue Skies
Blue Sky – Red Sunset
Why is the sky blue? What makes colorful sunsets? This simple demonstration will show you how these sky colors happen.
What Color is the Sky?
If you are a parent or are old enough to babysit younger relatives there is one question children ask that stumps most adults. It’s what color is the sky or why is the sky blue. This article will tell you why and do it in as simple a way as possible so that the next time a kids ask the question you have a good answer.
Why is the sky blue? Why are sunsets red?
Take a look at light through a prism and notice all the different colors that you can see. Light that looks white to our eyes actually is made up of many different colors. From Optics For Kids.
Artists were fascinated by Newton’s clear demonstration that light alone was responsible for color. An online course on color, vision and art.
You may ask yourself why is it that we only see the “visible” portion of light?

Which Wintergreen Candy Sparks the Brightest in the Dark?
In this experiment we will find out which brand of wintergreen candy produces the most sparks in the dark, a process called triboluminescence.
Wintergreen Candy and other Triboluminescent Materials
Go into a closet or other dark room. Take along a mirror and some WintOGreen Lifesavers. Wait for your eyes to adjust and then bite down on the candy real hard while watching in the mirror. If the candy hasn’t gotten soggy, your mouth will glow, and here’s why.
