The Electromagnetic Spectrum

Hold a clear, a frosted and a solid object up to a window as students read the three material words. On the spectrum sheet, have students say each wave's use as they label it.

Put seven wave types from radio waves to gamma rays in order, then compare their energy and uses. The directions on the page read: Read the text. Write the bank word for each numbered section of the spectrum on its line, in order from longest to shortest wavelength. An answer key is included.

Yes, both. We made it for 6th Grade waves and light, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with light and the electromagnetic spectrum. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

It can be reflected, absorbed, transmitted or refracted. A mirror reflects light in a neat pattern, and an object that absorbs light takes in its energy and warms up.

From longest wavelength to shortest, they are radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. As the wavelength gets shorter, the frequency and the energy get higher.

X-rays pass through skin but are blocked by bone, so doctors use them to take pictures of bones. The Electromagnetic Spectrum also names uses for radio waves, microwaves and gamma rays.
