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

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

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

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 about electricity, learners build and test a paper clip switch to turn on a light bulb.

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 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 make optical fibers out of strips of gelatin.

This is a web page that helps informal educators brainstorm on how to use a Pico Cricket (tiny computer) in an informal activity.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

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

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.
