Light! How do we see? What makes light? Find out everything you need to know through the Q&As on this site.

What is light energy? Here we'll learn about the properties of light and how pigments such as chlorophylls absorb light energy.

What is light? A detailed examination of what creates light, light spectrums, scientists' discoveries, and colored graphics. Appropriate for the older student or adult researcher.

Is that right side of your brain yearning to express its artistic side? This is a project that blends art with science. Learn about light and colorful shadows in these experiments where you mix and match various colors of light to create...

In this lesson for learners from 3rd-12th grades will learn to build an experiment chamber to test the effects of light on Brassica rapa roots, and compare their results with outcomes from plant experiments conducted aboard the...

This comprehensive article describes millions of years worth of the history of light and lighting.

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

A collection of tutorials and interactive resources, from basic to advanced, that explain concepts related to the science of light.

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...

This video segment adapted from Shedding Light on Science illustrates how light changes speed, and thus direction, in a process known as refraction. Includes background reading and discussion questions. [2:05]

Let's take it from the top! This week's adventure, Operation: Lights, Camera, Action!, takes children to a movie set where they work behind-the-scenes and explore different kinds of jobs such as production assistant (keeps track of the...

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again. Outfit yourself with a simple handheld laser pointer, a protractor, and Jell-O, and you're ready to get started.

This tutorial explains light absorption, reflection and transmission in a clear and concise manner. Provides a "Check Your Understanding" section as well as additional links on color and light.

Students will understand the concept of the ray model of light and how light interacts with matter and reflections.

In this physics classroom, students learn how and why light of certain frequencies can be selectively absorbed, reflected or transmitted.

This resource provides a concise overview of the speed of light and the Ole Roemer, the first man to measure it.

A very simple device to convert light into sound can be made by wiring a solar cell directly to headphones (or an earpiece). The solar cell converts light into electricity and the headphones convert electricity into sound. The limitation...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses light in relation to particles and waves. The difference between particles and waves is addressed along with...

Learners will determine the effect of placing objects made with different materials in the path of a beam of light. This lesson includes background information, guiding questions, directions, and a chart to record data.

Color theory I, "Color as Light", from artyfactory is an introduction to color theory in Art. This page provides an explanation with visual examples for help.

How is light visible? Examine this source to understand what light is and how it travels. Answer discussion questions and practice problems to better recognize light rays and know their functions.

[Free Registration/Login may be required to access all resource tools.] Students explain the ray model of light, describe the law of reflection, and investigate how images are formed from flat mirrors.

In this electronics science fair project, students will investigate how the output of an LED flashlight changes as its temperature increases.

In this electronics science fair project, students will make a simple dimmer switch and investigate the relationship between the resistance in the circuit and the amount of light produced. The Science Buddies project ideas are set up...
