Students investigate shadows and discover that the sun is a source of light.

In this module, students learn about the different sources of light, what causes darkness, and about shadows.

Students will explore sources of light in this lesson plan and generate their own questions for further investigation, then find answers.

In this lab experience, the students will be asked questions about characteristics of light and sound and whether these energy sources travel in straight lines. The teacher briefly demonstrates light and sound travel. Students will...

This probeware version of the Skills Practice Lab Brightness of Light from the chapter Light and Reflection uses a light probe to measure the intensity of light at different distances from a light source.

While reviewing various light sources, the source of colors (white, red, yellow, blue) are also discussed. The bouncing of light, the matching of colors, and seeing colors are all highlighted.

In this interactive, learn about sources of both beneficial and harmful radiation which exist in many forms all around us.

A very comprehensive unit including topics such as light and its source, visible sources of light, transparency of objects and much more. Also offers a resource list, blackline masters, and expectation list, expectation summary and a...

[Free Registration/Login may be required to access all resource tools.] Definition of visible light and what incandescence, luminescence and illumination are and how they occur.

Explore how light moves and describe how an object in a dark space only becomes visible when light moves into the space and illuminates it. Interactive activities, time-lapse videos, and images are used to enhance student observations as...

This site explores the various challenges Edison faced upon attempting to produce electric power. It contains a historical essay, a complete list of Edison's patents, information on the AC and DC currents, recordings produced by the...

Students will learn about the different types and sources of energy, including heat and light, electrical, potential, and kinetic energy.

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

This lab is designed to have students investigate the relationship between the distance you are from a source of light and the intensity of the light your receive.

Students learn how using a spectrograph helps us understand the composition of light sources. Using simple materials and holographic diffraction gratings (available online at a variety of sites, including Edmund Scientifics and the...

An introductory lesson describing the definition of energy, and highlighting different sources of usable energy.

Students are introduced to the concept of light pollution by investigating the nature, sources and levels of light in their classroom environment. They learn about the adverse effects of artificial light and the resulting consequences on...

Students will use observations and evidence to describe that objects can only be seen if they are illuminated by an external light source or give off their own light. Media is used to supplement student observations and encourage...

This resource provides information about light and shadows. In addition, there is a short quiz that can be taken.

Simulation that shows the diffraction of light through single or multiple slits. Simulation allows modification of the number of slits, slit width, slit separation, and the wavelength.

Students will investigate how light travels and what it does when it hits an object. Light sources will be used to represent a beam of light. Students will direct the beam toward various objects and materials. Through observations...

A discussion of the Advanced Light Source (ALS) facility and its use in material analysis and medicine.

Visualization that uses the Schwarzschild metric, showing the orbit light travels near a black hole.

This site provides a short explanation of light, how it travels, and the speed in which it travels. Many other concepts related to optics can be found on this site as well.
