What is lightning?
100
A circuit travels in this shaped pattern.
What is circular?
100
This thing turns on and off, creating closed and open circuits.
What is a switch?

What are poles?
200
Which is faster, the speed of light or the speed of sound?
What is the speed of light?
200
This type of electricity is caused when objects with opposite charges are attracted to each other. Hint: Our experiments with styrofoam beads and balloons.
What is static electricity?
200
These materials make good conductors of electricity.
What are metals, water, or your body?
200
The word for what happens when too many electrical appliances are put on one circuit.
What is an overload?
200
These types of poles attract each other.
What are opposites, or North and South?
300
Sound can travel fastest through this.
What is water?
300
Static electricity will stop and become neutral with these methods.
What are water and time?
300
A weak link in an electrical circuit that will melt and stop circuit. Hint: Starts with "F".
What is a fuse?
300
Like poles, North and North, or South and South do this.
What is repel?

What is loud?
400
The loss or gain of these parts of an atom, also known as -E, cause electricity.
What are electrons?
400
This power source changes chemical energy into electrical energy.
What is a battery?
400
This type of circuit means electricity can flow through the whole way without gaps or stopping.
What is a closed circuit?
400
The name of the area around a magnet that affects it.
What is a magnetic field?
500
This is what you call when sound bounces off things to create a visual image of an object, or how bats can "see".
What is echolocation or sonar?
500
This "I" word is what happens when you keep heat in and block it from escaping, or what you put on a live wire to prevent it from shocking you.
What is insulation?
500
Name the three things every circuit must have to work.
What are a power source (battery), conductor (wires) and item requiring power (lightbulb, buzzer)?
500
Found outside our room in the hall, this item contains switches that flip off when circuits become overloaded.
What is a circuit breaker?
500
The magnetic force is strongest around these parts of the magnet.
