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...

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.

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...

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...

Need a bright idea for an engaging lab? Watch your class light up as they explore the difference in efficiency between incandescent and LED bulbs! The resource makes use of simple materials and encourages learners to infer what's...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

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.

It's time to see the light  with a unit that focuses on light and geometric optics, including concave and convex mirrors. A variety of experiments, worksheets, and online activities are included. 

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...

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...

Assist your emerging scientists with construction of their very own spectroscopes. Individuals construct a spectroscope to identify elements used in varying lights within a particular environment. They conclude the activity with a...

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...

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...

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...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of...

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...

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...

Scholars learn the stories of the universe with a unit study on the cosmos. They model the universe, learn about the relationship with the electromagnetic spectrum, understand the big bang theory, and debate the existence of life on...

In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

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...

There are only 10 types of people in the world: those who understand binary and those who don't. The lesson includes four activities in which students learn binary, convert binary to images, understand CCD arrays, and interpret...

Design a mission over the rainbow. Small groups spend several weeks together determining a mission related to spectroscopy. The teams build spectrographs and analyze the design to determine whether it will carry out the mission. At the...

Explore color through an examination of pointillism and light. Class members view Georges Seraut's famous painting on a computer, zooming in and out to see the details and effects of the technique. They then cover how light and color are...
