A student turns on a computer to do homework. He then walks across the carpet and touches the metal chair to see a flash of light and feels a shock.
Which statement is the best explanation of what was observed?
Both actions are examples of electricity. The computer is powered by current electricity and the shock is caused by static electricity.
The computer is the only example of electricity. It is plugged into the wall and is powered by current electricity.
The shock is caused by static forces and it is not plugged into the wall so it could not be electricity.
The shock and flash of light was caused by current electricity from the computer. There is no static electricity in the room.
When is it easiest for a person to build up static electricity?
After a rain storm when they air is warm and humid
During the winter when the air is dry
After a lightning strike when the air is full of electricity
During the spring when the ground is wet
A student plugged in a Van de Graaff generator. As the band inside the generator began to move, a negative charge built up inside the metal dome. When the student placed his hand on the metal dome, his hair began to stand on end.
Which statement correctly explains the type of electrical energy in this scenario?
Current electricity is pictured when the charge jumps from the dome to the student’s hand.
Static electricity is pictured when the student plugs in the generator.
Current electricity is pictured when the student’s hair begins to stick out.
Current electricity is pictured when the generator is plugged in as electricity began to flow in the wire making the band rotate.
A student walks around his house in an effort to find examples of static electricity.

A teacher gave the class the following list of items and asked the class to determine if the item is an insulator or a conductor of electricity. How could the students prove their answers through an investigation?
Touch each object with a battery to see if it will produce a spark, if it does then it is a conductor, if it does not then it is an insulator
Put the objects in the sun. If the item becomes hot, it is a conductor of electricity and if the item is the same temperature then it is an insulator.
If the item is hard and shiny it’s a conductor, if the item is soft or flexible it is an insulator.
Create a complete circuit with a light bulb, replace one of the wires with the item. If the circuit is complete and lights up the bulb then it is a conductor if bulb does not light it is an insulator.
Students construct a simple circuit and place an item in the path. Which of the following materials will conduct electricity?
