Name the magnetic poles.
North and South.
100
What is a magnet?
A magnet is an object that attracts other objects made of steel, iron, and other metals.
100
What is the definition of a conductor? Provide an example of a good conductor.
A conductor is a material that allows electric charge to pass through easily. Metal; specifically copper is a good conductor.
100
What happens when a negatively charged object is brought near a positively charged object?
The objects will be attracted to each other and create static electricity.
100
Define closed and open circuits.
A closed circuit is when there is no break in the path for electricty to flow. An open circuit is when there is a break in the path which stops electricity from flowing.
200
What is magnetic attraction?
Magnetic attraction is when the north pole of one magnet is brought near the south pole of another magnet and the two pull toward each other.
200
Magnets are what shape?
Magnets can be many shapes. They can be bar shaped, circular shaped, and even horse-shoe shaped.
200
Define insulator and provide an example of a good insulator.
An insulator is a material that does not allow electric charge to flow through it. A good example of an insulator is rubber.
200
Explain what happens with electrons when you rub a balloon against your hair?
When you rub a balloon against your hair, electrons from your hair are transferred to the balloon; making the balloon negatively charged and your hair positively charged. Your hair is then attracted to the balloon.
200
What is a series circuit?
A series circuit is a closed circuit in which electric charge flows on a single path.
300
What is magnetic repulsion?
Magnetic repulsion is when the north pole of one magnet is brought near the north pole of another magnet and the two push away from each other.
300
What is the largest magnet in the world?
Earth is the largest magnet in the world.
300
Define electric current.
Electric current is the flow of electrical charges through a material; such as a conductor.
300
How did Benjamin Franklin discover static electricity?
He tied a metal key to a string on a kite and went out during a lightning storm. The lightning was attracted to the key.
300
What is a parallel circuit?
A parallel circuit is a closed circuit in which electricity can follow two or more paths.
400
What is magnetic field?
Magnetic field is the invisible force of attraction surrounding a magnet.
400
What is a compass?
A compass contains a metallic needle that responds to the earth's magnetic pull and works to determine direction: north, south, east, and west.
400
Describe what a power plant is and how gets electricity to your house.
A power plant is a station that generates power; either by burning fossil fuels or using wind. The electricity leaves the power plant and travels through a wire; which is made up of conductors and insulators, and travels to the house.
400
What happens when you put two balloons together that have the same charge?
The balloons repel each other.
400
Explain what happens in both a series and parallel circuit if one bulb goes out.
In a series circuit if one bulb goes out the other bulb goes out as well. In a parallel circuit if one bulb goes out the other bulb stays on.
500
Describe how to build an electromagnet, and explain how it works.
Attach a wire to both ends of a battery. Tightly coil the wire around a conductor. This creates a magnetic field around the conductor and allows the conductor to become magnetic.
500
Explain what happens when a compass is placed near a magnet.
The needle in the compass will be pulled toward the magnet and will no longer respond to the earth's magnetic pull.
500
How is electromagentic induction used to generate electricity?
Electromagnetic induction generates electricity by moving a conductor across a magnetic field.
500
You are walking across the carpet in your socks. You touch the doorknob and ZAP! You feel a shock. Explain what is going on here.
As you walk across the carpet electrons are transferring from the carpet to you making you negatively charged. When you touch the doorknob the electrons from you are attracted to the doorknob and create static electricity.
500
Demonstrate how to build both a series and parallel circuit.
Student should accurately build each circuit.
