Multiple Choice

A circuit has a switch, a wire, a battery, and a bulb. When the switch is flipped, the lights turn on. Which energy is used in this circuit when it is closed?

• Wind

• Chemical

• Electric

• Kinetic

Multiple Choice

A girl rubbed an air-filled balloon on her hair then put it on the wall and it stuck to it. What made the balloon stick to the wall?

• Static Electricity

• Wired Electricity

• Static Shock

• Balloon Power

Static Electricity

• Definition: Static electricity is the build-up of an electrical charge on the surface of an object. The reason that it's actually called static electricity is because the charges stay in one area for some time and don't flow or move to a different area.

• Rubbing the balloon on hair or even a carpet will allow it to stick to walls and even hair!

Multiple Choice

Name a material that makes the best conductor of electricity.

• Glass

• Rubber

• Wind

• Copper

Multiple Choice

What is the difference between a series circuit and a parallel circuit?

• In a series circuit, the electricity flows in multiple paths; in a parallel circuit, the electricity can follow more than one path.

• The electricity flows in one path for both.

• In a series circuit, the electricity flows in one path; in a parallel circuit, the electricity can follow more than one path.

• In a series circuit, the electricity flows in one path; in a parallel circuit, the electricity follows no path.

Multiple Choice

Describe electromagnets.

• Electromagnets use magnets to stick together.

• Electromagnets use magnets to hold copper's charge.

• Electromagnets are magnets.

• Electromagnets use magnets to make electricity.

Multiple Choice

Adam makes an electromagnet and puts some metal paper clips near it. What will happen when he closes the circuit?

• The paper clips will become attached to the magnet when the circuit is closed.

• The paper clips will repel one another.

• The paper clips will become fully charged.

• The paper clips will become magnets of their own.

Notice when the circuit is open again the paper clips fall.
