Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson plan then explains wavelength using a rope to make...

Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

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.

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

What is light energy? Here we'll learn about the properties of light and how pigments such as chlorophylls absorb light energy.

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.

Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet.

A brief explanation of the visible color wheel.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

A collection of several pages explaining the principles which underlie Rayleigh scattering of light.

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.

What is electromagnetic radiation and how does it work? Review a captioned graphic that explains electromagnetic radiation and the visible and invisible types of radiation on the electromagnetic spectrum.

Explore the electromagnetic spectrum and learn about each type of energy on the spectrum.

This is a site from NASA that contains an interesting and fun way to learn about the electromagnetic spectrum. Kate receives a strange riddle from her grandfather. Find out what it says and go through the gateway to the Land of the Magic...

This site details what radiation is, the physics of radiation, and radiative transfer as it occurs in nature. Content explores the electromagnetic spectrum, electromagnetic waves, properties of radiation, and solar radiation.
