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 design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

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