Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

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.

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. 

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...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

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...

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...

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...

View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

Ever made solar s'mores? Or recreated the solar system using peanuts? Astronomers young and old investigate all things solar using a variety of activities. Explore how the sun works, types of light it emits, and methods of charting the...

"Have respect for the dead!" Scholars investigate how science and religion often clash. As they look into the laws of science and the laws of religion, the legal ramifications at the federal level of both play into an argument they...

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,...

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...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....

Though this is meant to be second in a two-part instructional activity, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react...

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.

The second installment of a seven-part series focuses on the refraction of light and how it affects the colors we see. Learners consider how this concept connects to biosensors for cancer detection.

We all know photosynthesis happens, but why should we care? Here is a unit that covers everything young scholars need to know about photosynthesis. Hands-on activities, assessments, and lectures guide pupils though the physiology of...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

The moon takes just over 27 days to orbit around Earth. Young scientists position themselves as the earth as they rotate around the sun and hold the moon. This allows them to observe the patterns and phases of the moon.

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...

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...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...
