What is sound energy?
A doorbell ringing is an example of electricity being changed to this

100

What is wire?
In a complete circuit, this conducts the electric current around the circuit.

100

What is computer screen?
This is an example of electrical energy being changed to light energy.

100

What is use a copper core?
This is NOT a way to increase the strength of an electromagnet.

100

What is silver spoon?
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.

200

What is plastic?
A group of students is investigating several materials to be used as insulators. They have an rubber, wood, cloth, and a group of materials to choose from. Those materials are: brass, metal, plastic, and steel. This is the best insulator from these materials.

200

What is the switch is turned off?
In a simple circuit, the bulb is not turning on. This is why the bulb is not turning on.

200

What is series circuit?
Joey has a circuit. His circuit has one battery, wire, a bulb, and a switch. This is the type of circuit Joey has.

200

What is parallel circuit?
La'Fonda is working on a circuit. Her wires are parallel. This is the type of circuit she is working on.

200

What is only one path?
In a series circuit, there are this many paths for electrical current to flow.

300

What is the rest of the bulbs stay on?
In a parallel circuit, this is what happens when one bulb goes out.

300

What is multiple directions?
In a parallel circuit, electricity can flow this way.

300

What is opposite poles attract?
Nevaeh has two bar magnets. Her N and S poles are facing each other. This is an example of what?

300

What is like poles repel?
Nevaeh has two bar magents. Her N and N poles are facing each other. This is an example of what?

300

What is Lisa made a temporary magnet with the needle?
Lisa touched a needle to a magnet and then observed that a paperclip would attach to the needle. This best describes what just happened.

400

What is at both poles?
This is where the strength of a magnet is the greatest.

400

What is the same poles of the magnets are facing each other?
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.

400

What are paper clips, pennies, and screws?
Ricky has an instrument that sees if materials conduct electricity. He also has a group of materials that help to complete the circuit. These are examples of what could complete the circuit.

400

What is count how many paper clips each magnet can pick up?
Max wants to figure out which of two magnets has the most attraction strength. This is what Max should do to figure out the strength.

400

What are 10 nails?
Look at the graph provided. This graph shows the results of an investigation with an electromagnet. If a 35-gauge wire is used, this is how many nails it will pick up.

500

What is more strength?
When making an electromagnet, if you have more coils, you have this.

500

What is material that does allow electricity to flow through it?
This describes what a conductor is.

500

What is material that does not allow electricity to flow through it?
This is what an insulator is.

500

What is closed?
In a circuit, if the bulb is turned on, the switch is this.

500

What is the closed switch allows for the electricity to flow in a complete path?
In a circuit that has a closed switch, this is why the bulb turns on.
