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.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

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 will create a speaker using a paper cup, magnet, and enameled wire. Also included in this activity is a Mr.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

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

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

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.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

In this activity, learners will investigate static electricity as they create waterless snow globes.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

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

Play keep away from your cat by using a static charge to suspend a piece of tinsel in the air. This Exploratorium produced activity also features videos to help create and learn about this phenomenon.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
