Kids learn about the science of the light spectrum. Wavelengths and frequencies of the electromagnetic waves including visible light, primary colors, and subtractive colors.

You'll find a wealth of resources at this site dedicated to color! Easy-to-read discussions can be found on topics ranging from the science of light to complementary colors and the color wheel. All special terms are highlighted and...

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

Explains where visible light fits into the electromagnetic spectrum and the wavelengths for the different colors we see.

This lesson will introduce light waves and describe how a particle can travel as a photon or a wave. It is 4 of 4 in the series titled "Light Waves."

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

Discover the relationship between light and colors in this brief lesson. Links to related color identification activities, Color Memory Challenge and Identifying Colors Quiz. Immediate feedback given to responses that includes...

Read about the visible light spectrum and learn the frequencies and wavelengths for each of the primary and secondary colors.

Site explores colors and how they are formed. Provides three different activities to explore color.

A thorough, multipage discussion of color and color television sets that explains how an image is formed on the television using red, green, and blue light. Understandable discussion, excellent graphics, and many interactive Java applets.

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

A simple experiment through which students observe the connection between color and heat and prove that dark-colored objects and light-colored objects heat at different rates, even when exposed to the same heat or light source.

A short explanation of how we see color and what each of the primary and secondary colors symbolize.

Learn about colors of light by exploring how prisms work. Discover the different colors of the spectrum and how the visible light is what we see.

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...

This animation discusses light and the properties of light in a storybook format. The animations cover the colors of the rainbow (ROYGBIV) along with prisms, light waves, reflection, and refraction.

[Free Registration/Login Required] Are there colors we don't see? This simulation addresses that question by exploring light as an electromagnetic wave. Learn how the electromagnetic wave relates its wavelength and frequency to the...

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...

Students investigate the properties of visible light and the sequence of colors in the spectrum using light shone through water and prisms. The lesson and accompanying slideshow can both be downloaded.

Students practice converting between RGB and hexadecimal (hex) formats. They learn about mixing primary colors in order to get the full spectrum of colors and how to average pixel values.

Students apply everything they have learned over the course of the associated lessons about waves, light properties, the electromagnetic spectrum, and the structure of the eye, by designing devices that can aid color blind people in...

What is light? Illustrated discussion of the speed of light, how we see colors, and how light helps us.

A simple activity to demonstrate how light separates into colors when it passes through water acting as a prism.

Students will learn about refraction and the scattering of sunlight as it enters the atmosphere, which causes the colors in light to separate, giving us blue skies and colorful sunrises and sunsets.
