Answer:
Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as in a computer). Try this project to build your own simple circuit and use it to test which common household materials conduct electricity.
Background
You probably hear the word electricity a lot, but what does it actually mean? In everyday use electricity typically refers to electrically charged particles (called electrons) moving through metal wires. The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. You will notice this if you have ever plugged something into a wall outlet. The prongs on the plug and the wire inside the cord are metal but they are surrounded by plastic or rubber insulation so you do not get shocked when you touch the cord!
