Uen: I'll Build You a Rainbow
In these three activities, students explore the colors of the spectrum in white light.
University of California
Interactive Extreme Ultraviolet Skymap
A map showing a view of the night sky is given; sources of extreme ultraviolet light are marked. Visitors analyze the spectrum from these parts of the sky and attempt to determine which star type the spectrum most closely resembles.
Physics Central
Physics Central: Physics in the Snow: Snowy Colors
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.
University of Colorado
University of Colorado: Physics 2000: Temperature and Absolute Zero
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.

Lucianne Walkowicz shows us the waves just beyond our perception: microwaves, radio waves, x-rays and more. [5:58]
Physics Classroom
The Physics Classroom: Light Waves and Color: Blue Skies and Red Sunsets
Students will focus on the interaction of sunlight with atmospheric particles to produce blue skies and red sunsets.
Simon Fraser University
Chem1 Virtual Textbook: Spectra and Interaction of Light and Matter
Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses continuous spectra and line spectra using examples and charts to assist in the understanding.
TED Talks
Ted: Ted Ed: What Is Color?
Colm Kelleher describes the physics behind colors- why the colors we see are related to the period of motion and the frequency of waves. [3:09]
Physics Classroom
The Physics Classroom: Refraction and the Ray Model of Light: Rainbow Formation
Understand the physics behind Roy G. Biv, and how rainbows are formed by drawing upon our understanding of refraction, internal reflection, and dispersion.
Science Buddies
Science Buddies: Rainbow Fire
Astronomers can determine the atomic composition of distant stars by measuring the spectrum of light emitted by the star. Sound cool? Well in this project you can do something similar by observing the color of flames when various...
University of Colorado
University of Colorado: Physics 2000: Spectral Lines
Several pages from an excellent site which describe the science of spectroscopy. The unique atomic emission (and absorption) line spectrum of elements are illustrated and explained. Includes a Java applet depicting the quantum energy...

Teach Engineering: Building a Fancy Spectrograph
Students create and decorate their own spectrographs using simple materials and holographic diffraction gratings. A holographic diffraction grating acts like a prism, showing the visual components of light. After building the...
Exploratorium
Exploratorium: How to Build a Spectroscope
Instructions for how to construct a spectroscope from basic materials, which can be used to study colors produced by light from different sources. Adult supervision may be required for the use of the utility knife. Includes an...
TeachEngineering
Teach Engineering: Rgb to Hex Conversion
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.
Physics Classroom
The Physics Classroom: Blue Skies and Red Sunsets
This high school resource shows how the blue of the skies and the red of the sunsets can be explained by the interaction of sunlight with atmospheric particles which causes scattering of light.
NASA
Nasa's the Space Place: A Trip to the Land of the Magic Windows
Explore the electromagnetic spectrum and learn about each type of energy on the spectrum.

Teach Engineering: The Three Color Mystery
Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as...
TeachEngineering
Teach Engineering: Thirsty for Gold
Student teams conduct an experiment that uses gold nanoparticles as sensors of chemical agents to determine which of four sports drinks has the most electrolytes. In this way, students are introduced to gold nanoparticles and their...

Pbs Learning Media: Above the Clouds: Telescopes on Mauna Kea
This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe...
Science Education Resource Center at Carleton College
Serc: Mn Step: Why Is the Sky Blue?
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.
Sophia Learning
Sophia: Radiation and Energy: Lesson 2
This lesson discusses the light spectrum and its influence on living things. It is 2 of 3 in the series titled "Radiation and Energy."
