Amazing Northern Lights Time Lapse

There's more to that glowing ball of light in sky than most children realize. From the overall structure of the solar system, to the changing of the seasons, these hands-on lessons open the eyes of young scientists to...

Your class might be surprised to learn that mirrors have been around since the first century AD! Young scientists explore reflection and refraction of light through a series of challenges. They use this knowledge to design their own...

Someone stole a diamond-making machine. Who done it? Scholars use forensic science at six different stations to determine the culprit. They analyze fingerprints, use their senses, and complete chemistry experiments to determine the...

Light the way to a better understanding of UV radiation. After exploring how UV beads work, future engineers design investigations to answer questions about UV radiation. They then create and test prototypes of a device that detects UV...

Students view artwork and navigate the Internet, and read books to learn about the Aurora Borealis.  In this Northern Lights lesson, students complete a KWL and separate the facts from the myths about the Northern lights....

Beam me up, Bill! Explore how beams of light behave when they strike flat and curved surfaces. Bill bends light using a nifty contraption that streams three beams through a straight and a curved piece of plastic. He also defines and...

A LED light, a camera, and a battery can provide the means to sending hidden messages. This is a demonstration that is bound to captivate your class. You can have learners get into groups after they have watched the video to explain the...

Shine a little light on the topic of visible light with a quick video lesson. The lesson highlights the basics of visible light including wavelength and electromagnetic energy. Learners discover how humans' eyes process the...

An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

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...
