Understanding Light: Lesson 2 - The Electromagnetic Spectrum

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

Do you have blossoming astronomers who seek to understand the electromagnetic spectrum? Assist them with exploring electromagnetic radiation and the electromagnetic spectrum as the class conducts various activities to demonstrate...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

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...

Two sequential parts to this lesson plan introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

All this talk about seeing the light... but, what is it, and how do we see it? Science students learn the basics of the nature of light in a narrated video that discusses concepts such as how light behaves, the electromagnetic spectrum,...

What can the electromagnetic spectrum tell us about the sun? As it turns out, quite a bit! See the sun in a whole new light with a video from NOVA's Sun Lab unit. The narrator describes the electromagnetic spectrum in terms of visible...

Did you know that the visible light wavelengths comprise only one inch of the electromagnetic spectrum that extends over 2,000 miles? Yet even the visible spectrum provides so much information. The Hydrogen spectrum is illuminated as an...

Four modules are a part of this stellar lesson plan. Space scientists view the electromagnetic spectrum, they generate waves on a computer screen in order to measure frequency and wavelength, discover how light is related to temperature,...

Any work with light, lenses, lasers, or mirrors is called optical engineering. Optical engineers bend and bounce light to make it useful for humans. Examples are telescopes, invisibility, nanomedicine, and solar energy. This...
