What is a color spectrum? Simple, it's comprised of the colors of the rainbow. Have the classs read a passage about the color spectrum and then complete two short answer activities. 

Who doesn't love a rainbow? Little ones adore them, so why not make rainbows the subject of your next art project. Your class can use watercolor to paint rainbows. As they do, have them identify the colors in the rainbow, talk about how...

View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

Photocopy single-color images onto acetate transparencies and either demonstrate or have your class experience the combination of colors to produce images. Children will learn that cyan, magenta, yellow, and black combine to make all of...

Humans can only see visible light, but some insects can see ultraviolet light. Through a simulation, pupils explore how we see colors using one bulb. It moves on to demonstrate how we see colors by mixing three different bulbs (red,...

There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

Students participate in a discussion of the sky and colors. They watch a demonstration of how colors can change. They examine the issue of if weather should be a part of their coursework.

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

Students explore a variety of colors and shapes after reading the story, "Planting A Rainbow," by Lois Ehlert. The tracking and reading of labels attached to diagrams form an experience in vocabulary development in this lesson.

Students explore color recognition through mixing the primary and secondary colors together. They color in an online rainbow using primary and secondary colors, identify the colors on a color mixing poster, then mix the colors using...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

Here's a colorful resource about spectra. An intriguing instructional activity teaches pupils about diffraction grating and about absorption and emission spectra. They see how to represent spectra using line plots and try out this skill...

Where does bad light end up? In a prism! The presentation covers light, mirrors, lenses, and the structure of the eye. It also provides explanations of reflection, refraction, concave and convex mirrors and lenses, and a comparison of...

Young scholars discuss whether all colors are in the rainbow. In this physics lesson, students defend their ideas and present persuasive arguments to support them.

First graders experiment with prisms to explore sequence of colors of light created.

Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

High schoolers examine rainbow components, spectral colors, colors perceived by the eye, hot solids, glowing rarefied gas, absorption, that light is a wave, and optics.

Nature provides a rainbow of colors at one's fingertips. A hands-on activity uses natural plant materials to create all-natural dyes. Plants range from fruits and vegetables to flowers and greens. After extracting the pigments, eager...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students spin separate colors into a new color just as the Magic School Bus kids did.
