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.

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...

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...

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...

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...

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. 

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...

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...

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...

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.

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...

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...

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...

Explore a land far, far away with a well-designed lesson that examines electromagnetic imaging as a way to obtain information about galactic structures. Learners begin to see the importance of looking beyond the visual spectrum to...

Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

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,...
