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

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.
