Circuits
To Transfer or Not to Transfer??
It's electric!
Let's experiment...
What's the mode?
100
What do we call the type of circuit that only allows one path for the electricity?
series circuit
100
What do we call a material that will transfer electricity?
a conductor
100
What type of electricity is lightning?
static electricity
100
Give 2 examples of insulators.
rubber, air, wood, plastic, glass
100
Give an example of electrical energy being transferred into heat energy.
microwave, oven
200
What do we call a circuit with no gaps?
closed circuit
200
What do we call a material that will not transfer electricity?
an insulator
200
What type of electricity travels through a circuit?
current electricity
200
How did you know which items in your bag of "junk" conducted electricity and which did not?
If the light bulb stayed lit, it was a conductor of electricity.
200
Give an example of electrical energy being transferred into motion.
fan
300
What do we call a circuit with a gap?
open circuit
300
What do we call a material through which electricity has difficulty traveling through?
a resistor
300
What do we call the result of too much electric current flowing through a conductor?
short circuit
300
Draw a series circuit with a bulb, a battery, and wires.
see board
300
Give an example of electrical energy being transferred into light.
lamp
400
What do we call a circuit that provides more than one path for electricity to travel?
parallel circuit
400
When lightning is visible why do lifeguards require all people to stop using the pool?
Because water is a conductor, so if electricity struck the water it would be life-threatening.
400
What is a way to create static electricity?
rub 2 items together
400
Give 2 examples of conductors.
metal, water, copper, people
400
Give an example of electrical energy being transferred into sound.
radio, CD player, iPod
500
What type of circuits are used to wire your home with electricity?
parallel circuits
500
Remember my story of carrying my little brother home from the woods. His foot touched the electric fence, but I felt the shock. Why?
Because people can conduct electricity.
500
What do we use in our homes to easily open and close circuits?
switches
500
What is happening when 2 items are rubbed together creating static electricity?
There is a build-up of electrons, giving one of the items a negative charge.
500
Give an example of electrical energy being transferred into mechanical energy.
table saw, drill, etc.
