electrons
protons
neutrons
atoms
Which image correctly shows how electrons flow through a battery? *red arrows show direction of electron movement
a.
b.
c.
d.
This is a parallel circuit. Why would this type of circuit be a better option in houses and schools than series circuits?
if one of the bulbs died, it would not effect the other bulbs on the circuit.
if one of the bulbs died, it would cause the rest of the bulbs in the circuit to fail.
if the battery dies, both bulbs stay on.
the battery cannot die in this type of circuit.
Opposite charges _________________.
attract
repel
push away
remain neutral
Electric currents are similar to water currents because...
they both deal with the flow of particles from one area to another
water is made of electricity
push away
remain neutral

copper
wood
plastic
glass
Important safety features of wires include using an _________________, like rubber, around the metal wire to prevent electrocution.
insulator
conductor
electron particle
exposed wire
To create static charge (static electricity) a material must lose or gain ___________________.
electrons
protons
neutrons
nuclei
In this closed circuit, the flow of electrons is counter-clockwise (direction of red arrows) What direction would the electrons move if the battery was flipped?
the electrons would move clockwise
the electrons would continue to move counter-clockwise
the protons would move clockwise
the neutrons would begin to move counter-clockwise
You have two statically charged balloons.
Which of the following is the best reason why the balloons push each other apart?
The balloons have magnetic charges
The balloons have no charges
The balloons have opposite charges
The balloons have the same charge
Ashley is classifying some objects as conductors or insulators. What is the difference between conductors and insulators?
A conductor allows electrical current to flow through it easily, while an insulator does not.
An insulator allows electrical current to move through it easily, while a conductor does not.
A conductor has a static charge, while an insulator does not.
An insulator is a metal, while a conductor is not a metal.
Greg is using a circuit to test materials to determine which ones are good insulators. What happens when he tests a good insulator?
He gets an electrical shock.
No current flows through the circuit.
A strong current flows through the circuit.
The current flowing through the circuit flows weakly and then strongly.
Which of the following statements is true:
electrons flow from negative charges to positive charges
electrons flow from positive charges to negative charges
electrons only flow when a current of water is present
electrons do not flow under any circumstances
