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...

Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

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...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...

Stars seem to be a far away mystery... but it turns out we know much more about stars than one would think! An engaging lesson shows learners how to read a light spectrum to determine the temperature and chemical makeup of a star....

Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

Elements don't have fingers, but they have fingerprints! An interactive simulation gives young scientists the opportunity to study orbital changes of an atom and the corresponding spectrum reading. They realize how each atom has a...

Stars are too hot to visit, so how do we know what different stars are made of? An enlightening simulation uses a spectrum graph to show the various electron emission and absorption reactions. Scholars experiment with both helium and...

Go study the universe. Pupils learn seven aspects about astronomy and astronomers. They begin to learn about constellations; distance and motion between objects; gravity; the electromagnetic spectrum; dark matter and energy; and teams of...

In this online interactive history quiz worksheet, students respond to 10 short answer and essay questions about the life and accomplishments of Isaac Newton.

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

How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change....

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...

Learn all about stars and the electromagnetic spectrum in this series of activities.

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.

[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...

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

This lab is designed to allow students to look at the factors affecting the location of different colors formed by diffraction grating.

Several pages from an excellent site which describe the science of spectroscopy. The unique atomic emission (and absorption) line spectrum of elements are illustrated and explained. Includes a Java applet depicting the quantum energy...

This interactive tutorial illustrates how spectrometry is used to study, identify, and quantify materials.
