Just as some materials allow the flow of electricity, others do just the opposite and stop the flow. We call these materials insulators. You have probably heard that it is pretty safe to be in a car during a lightning storm. That is because the tires of the car are made of rubber, and rubber is an insulator. Electrical wires are wrapped in insulators.
Insulators provide needed protection from high-voltage lines for people who work on power lines.
Click on the man or the car above to find several experiments that demonstrate static charge, conductors, and insulators. Be sure to have an adult help you. You might ask your teacher to let you demonstrate one of these experiments in class. You should always be very careful around electricity. Make a flashlight by using two wires, a toilet paper roll, a small battery, and tape.
