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...

A totally cool concept! Choose your base color, your scheme (monochromatic, etc.) and the computer will show you what other colors go with it! There are even settings for various levels of color-blindness. A really cool art tool!!

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

A brief explanation of the visible color wheel.

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...

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

Remote sensing, false-color satellite images, and the electromagnetic spectrum are all covered in this fun site about Echo the bat. These topics are addressed in both a story book and text book fashion and are supported by a full set of...

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...

This website has three different projects from which to choose on the topic of why the sky is blue. Also, you can scroll up to learn more about why the sky is blue.

The Discovery Channel provides numerous lesson plans dealing with the physical sciences. Content is organized by grade level, but all lesson plans include suggestions for adaptations for older or younger audiences.

Science experiment that demonstrates chromotography. Includes full list of materials, procedures, and scientific explanation of what happens with different colors when they are soaked with water.

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

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...

This instructional activity contains the following labs: Rainbows, Refraction with Prisms, and What Color Is It? Students will study light by reading various nonfiction texts and viewing a video instructional activity. Then students will...

An experiment to demonstrate how to make a rainbow and why they form.

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