Static electricity is the buildup of electric charges on an object. Which of the following is the best way to create static electricity?
banging two conductors together
plugging in a plug to the outlet
rubbing two insulators together
turning on a light
Which object would be a conductor of electricity?
iron nail
wooden spoon
rubber swing
plastic bag
The diagram below shows a light bulb connected to a battery by a wire. What will happen with the light bulb?
It will light up, because there is a power source.
It will not light up, because there is no switch.
It will not light up, because the pathway doesn't make a complete loop.
It will light up, because the battery is positive.
Which of these is required to make a circuit?
two or more batteries
a closed loop
a switch
a lightbulb
Which would make the best insulator?
aluminum
plastic
iron
water
Marcus has a circuit that uses a battery to light up a light bulb. He needs three wires to make his circuit. He changes the circuit to have a paper clip attached to wire 2 as shown in the picture below.
What should Marcus predict will happen when he connects wire 3 to the paper clip?
The wires will catch on fire
He will get shocked.
The light bulb will light up.
The battery will burn.
Lightening is......
static electricity
current electricity
Select the insulators
rubber band
glass bowl
metal pipe
paper clip

Electrical cords are made up of two layers. The wire inside is made of metal. This is surrounded by a cover made of plastic or rubber. How do the wire and cover compare in their ability to conduct or insulate electricity?
The wire conducts just like the cover.
The cover conducts and the wire insulates.
The cover insulates and the wire conducts.
The cover and wire both insulate.
