Will this circuit work correctly?

• Yes, because the circuit is a complete loop and it will allow electricity to flow.

• No, because the wires are not touching both ends of the battery.

• Yes, because the circuit has the three basic parts.

• No, because the wires are not touching the end of the light bulb.

Why are wires needed to make a circuit work?

• To connect parts of the circuit and conduct electricity.

• To provide energy to the circuit.

• To make the circuit look cool.

• To show that the circuit conducts electricity.

Does the image represent a complete circuit?

• Yes

• I am not sure

• No

• What is a complete circuit?

What is a good indicator that an object is an insulator?

• It allows the flow of electricity easily.

• It looks like an insulator.

• It does not allow the flow of electricity easily.

• It is made of rubber.

Samatha holds a magnet to the side of the cup.

There is iron in the cup and the iron begins to move towards the side of the cup where the magnet is placed. Why is the iron moving toward the magnet?

• The magnetic force is pulling the iron towards the magnet.

• The iron likes how the magnet looks.

• The iron just happens to float that way.

• The magnetic force pushed the iron away.
