A group of students is investigating several materials to be used as conductors. They have an iron nail, copper wire, aluminum foil, and a group of materials to choose from. Those materials are: cloth fabric, paper towel, plastic foam, and a silver spoon. This is the best conductor from these materials.
What is silver spoon?

La'Fonda is working on a circuit. Her wires are parallel. This is the type of circuit she is working on.
What is parallel circuit?
200
In a series circuit, there are this many paths for electrical current to flow.
What is only one path?

In a parallel circuit, this is what happens when one bulb goes out.
What is the rest of the bulbs stay on?
300
In a parallel circuit, electricity can flow this way.
What is multiple directions?

Lisa touched a needle to a magnet and then observed that a paperclip would attach to the needle. This best describes what just happened.
What is Lisa made a temporary magnet with the needle?
400
This is where the strength of a magnet is the greatest.
What is at both poles?

De'Shawn has two doughnut magnets on a pencil. He pushed the magnets together, but they came apart as soon as he let go. This is the reason why the magnets are staying apart.
What is the same poles of the magnets are facing each other?
