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.

How many of your pupils play an instrument? A musical science lesson will help all of them understand how string instruments work. Young scientists construct a string-and-pulley system to test frequency and pitch. The lesson...

Why do soybean plants that are planted weeks apart in the spring mature simultaneously in the fall? Four independent activities cover the history of phytochrome research, scientist collaboration, the electromagnetic spectrum, and...

Describes the characteristics of light, presents two formulas for calculating its wavelength, and provides a table of the different wavelength ranges across the electromagnetic spectrum.

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.

A discussion from Georgia State University of different types of mirrors and the images which they create. Discusses different instruments which use mirrors to produce images.

Learn how an infrared thermometer works and what each of its parts does. A chart lists the different applications of infrared thermometers by the wavelength each emits.
