Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks. 

Uncover the exciting interactions of light energy and matter ranging from color to optical illusions. Participants explore color using red and green apples, differences between reflection and refraction, and descriptions of related...

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

There is a scallop that relies on sight so much that it actually has more than 100 eyes! There are many species that rely heavily on one sense or another. An online interactive resource has youth read about several of these animals. The...

Consider this online interactive activity as a way to practice the names that often accompany human anatomy, such as the crown of the head and the roof of the mouth. Learners select an anatomy word with a double meaning from a drop-down...

A marine environment covers the majority of the earth but is arguably the least understood. Teach young scientists about the characteristics of oceans and ocean species using an interactive online lesson. The in-person or remote learning...

Instructional module focusing on light. Discussion includes historical development of particle versus wave theories and the scientific studies leading to the understanding of light waves today. Site also includes an interactive practice...

In this interactive physics tutorial about refraction, students investigate the topic of the direction of bending of a light wave.

In this interactive lesson about electromagnetic waves students will explore what they can see, what they can't, and what they know about the wave nature of this thing called "light."

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics. Describe how the results lead to the photon model of light.

A few short, interactive activities on light waves can be found on this site. Numerous others links and teacher resources are posted here as well. A good background on light is offered for teachers.

This illustrated physics tutorial explains the electromagnetic and visible spectra of light using illustrated examples and interactive practice problems.

Students will focus on the interaction of sunlight with atmospheric particles to produce blue skies and red sunsets.
