Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

A magic lantern is a light that projects an image onto a screen.

This activity guide includes instructions for building a spectroscope using a standard classroom overhead projector.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this activity, learners investigate how some butterfly wings get their color.

Learners use two mirrors to explore how images of images of images can repeat forever.

Put on a pair of gloves and be the conductor of your invisible orchestra!

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this activity, learners investigate the properties of graphene and graphite.
