In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

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

In this activity, learners make optical fibers out of strips of gelatin.

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

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
