Rainbows of Light: The Visible Light Spectrum
Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson then explains wavelength using a rope to make waves.
Exploratorium
Blue Sky
Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...
Colorado State University
What's the Difference Between Blue Light and Red Light?
Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...
Cornell University
Light Waves: Grades 9-12
Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

A Splash of Color - Is Pure Water Colorless?
What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...
University of Colorado
Designing an Open Spectrograph
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...
Baylor College
Rainbow in the Room
Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...
Exploratorium
Spectra
Make a class set of spectrum tubes by first purchasing some diffraction grating, and then constructing the tools with mailing tubes or shoe boxes. If you aren't up for assembling them, you could purchase prepared spectroscope kits. This...
Science 4 Inquiry
It's Not All Visible
Electromagnetic waves travel though empty space, something no other wave type can accomplish. Young scientists learn more about the entire spectrum of electromagnetic waves. They sort cards and apply their knowledge to create models of...
IOP Institute of Physics
Physics in Concert
What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Sensing the Invisible: The Herschel Experiment
The electromagnetic spectrum includes everything from very powerful gamma rays (which are used to treat cancer) to much weaker radio waves (which include microwaves). Through a hands-on activity, scholars explore the temperature...
University of Waikato
Māui and the Sun
Using a Maori legend, How Maui Tamed the Sun, youngsters are introduced to the importance of sunlight to civilization. Teach them about nuclear fusion that occurs to produce the solar energy we later receive on Earth as...
Discovery Education
Sonar & Echolocation
A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
University of Texas
Multi-wavelength Astronomy
Explore a land far, far away with a well-designed lesson that examines electromagnetic imaging as a way to obtain information about galactic structures. Learners begin to see the importance of looking beyond the visual spectrum to...
Curated OER
Reflection and Refraction
What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...
