In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

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.

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

In this activity, learners explore the concept of conducting or insulating electricity.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.
