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

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

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

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

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.

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

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.
