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...

Why did the waves get into a fight? They were tired of each other's interference. Scholars observe the wave patterns from dripping water, sound waves, and light waves. They vary the spacing, build barriers, and increase the number...

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

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...

In this AC waveforms worksheet, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

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...

In this online interactive history worksheet, students respond to 10 short answer and essay questions about the accomplishments of Max Plank. Students may check some of their answers on the interactive worksheet.

In this online electricity worksheet, students are asked 10 questions about electric current and battery energy, an online answer key provided.

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...

In this online interactive physics quiz worksheet, students respond to 5 questions. Students may check their answers for accuracy.

In this online interactive history worksheet, students respond to 9 short answer and essay questions about the achievements of Niels Bohr. Students may check some of their answers on the interactive worksheet.

[Free Registration/Login Required] Are there colors we don't see? This simulation addresses that question by exploring light as an electromagnetic wave. Learn how the electromagnetic wave relates its wavelength and frequency to the...

See what happens when you mix different colors of lights.

This animation discusses light and the properties of light in a storybook format. The animations cover the colors of the rainbow (ROYGBIV) along with prisms, light waves, reflection, and refraction.

An introduction to the concept of the visible light spectrum provided in an animated format.

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

Make waves with a dripping faucet, audio speaker, or laser. Add a second source or a pair of slits to create an interference pattern.

The Sound and Light interactive investigates these two forms of energy. Students will enjoy exploring how sound and light are created, travel, and can be controlled.

An online exploration where students learn the basics about light and the properties of waves and the electromagnetic spectrum. Students will also learn how to measure wavelength and frequency so they can understand the electromagnetic...

This site from the National Aeronautics and Space Administration provides information on the subject. "An infrared camera sees heat, rather than light. Can you match up the face in the infrared image with the same face in visible light?"

[Free Registration/Login Required] Move the light source to see what happens to the reflected ray as you change the angle of the incident ray.
