This is the unit used to measure electrical current.
What is an amp?
100
Magnets attract what type of material.
What is iron?
100
This is how you can create a small electromagnet in class.
What is wrap a nail or piece of metal in copper wire and run a charge through it with a battery?
100
These are the two types of circuits we built in class.
What are series and parellel circuits?
100
If voltage increases this happens to the current.
What is increases also?
200
This is the force or pressure that pushes the current through a wire.
What is a volt.?
200
Magnets have the strongest attraction or repulsion at this part of the magnet. (You may use a bar magnets to show us, but not to test it out.)
What is at the poles or ends.
200
This is the largest electromagnet in the world.
What is Earth?
200
What kind of circuit would you want in your home and why.
What is a parallel circuit, because if one light or load on this circuit goes out the rest of the circuit is left unharmed.
200
Batteries provide what kind of power
What is DC (direct current)
300
This is anything that opposes or slows down the flow of electric current.
What is resistance? (I will accept insulator since this is what causes resistance.)
300
Magnets all have a universal "magnetic force", tell what this is.
What is the force of attraction or repulsion generated by electric charges?
300
Name two things we observe as a result of Earth's magnetic field.
What is northern and southern lights, and compasses pointing north.
300
The simplest series circuit requires at least three items, name them.
What is a power source (battery), conductor (wire), and a load (light).
300
This is why lightning rods protect buildings
What is they are grounded so the charge is directed into the ground instead of the structure.
400
This is how many volts a double A battery has versus a car battery. (Must get both for the points)
What is 1.5 volts and 12 volts
400
The property of magnetism is due to what "aligning"
What are domains?
400
This is a solenoid.
What is a coil of wire with an electric current running through it.
400
Please draw a series circuit on a sheet of paper with your group. Label as needed and make it clear.
Answer will vary
400
Lightning, being shocked, or sparks from static cling are examples of this.
What is electrical discharge?
500
If you had a voltage of 18 as caused by two 9 volt batteries, this would be your amperage with no resistance.
What is 1.8 amps
500
Name two ways to "break" a magnet.
What are heating it up and banging or dropping it?
500
Explain why Earth acts as a giant electromagnet.
Because of it's solid iron inner core and molten flowing outer core the Earth creates a very large magnetic force with it's poles near the north and south pole of the planet. This creates a magnetic field around Earth that protects us from the Sun's radiation.
500
Please draw a parallel circuit on a sheet of paper with your group. Label as needed and make it clear.
Answers will vary.

Why is STATIC electricity usually not found in materials that are good conductors.
Static means still and electrons usually move through a conductor, so this is why static electricity is built up in things like material (an insulator) and discharges on things like metal (conductor).
