This is an example of current electricity

• Hair standing up after going down a slide

• Using a toaster to cook slices of bread

Plastic coating on wires

• will shock you!

• insulates the wires to make them safer to touch.

• acts as a conductor of electricity

• None of the above

One difference between electricity flowing in a circuit and electricity in our natural environment is this:

• Electricity does not move around in natural environments.

• There are no sources of electricity in natural environments.

• Electricity is not positive and negative in natural environments.

• There are no switches that control electricity in natural environments.

Bob's group in science class built the circuit pictured. Will the light bulb light up? Why or why not?

• No, because it needs a switch.

• No, because it needs a second wire to complete the circuit.

• Yes, because there is a battery.

• Yes, because there is a wire and a bulb.
