SONG!: What Is Electricity by Veritasium
LYRICS
1, 2, 3 A song about 'lectricity
because it powers our lives
makes it possible for us to thrive
because it powers our lives
makes it possible for us to thrive
Oh, 4, 5, 6, volts of potential difference
makes electrons go round
if the circuit is complete and sound
Circuit's closed
Voltage There
Current Flows
Power Everywhere
We use AC,
in factories
and homes because we can transform it
High voltage
transmits with lower loss
but low voltage is best for safety
I said what is electricity?
Well, so 1,2,3 a song about 'lectricty
because it powers our lives
makes it possible for us to thrive
because it powers our lives
makes it possible for us to thrive
Oh, 4,5,6 volts of potential difference
makes electrons go round if the circuit is complete and sound
Heat makes steam
turns turbines
and a magnet in
coils of wires
We use AC,
in factories
and homes because we can transform it
High voltage
transmits with lower loss
but low voltage is best for safety
I said what is electricity?
Oh yeah, Oh yeah, C'mon!
How'd it be
no energy
of the electrical persuasion
I know we'd
have no computers
no internet or mobile phones yeah
Powers the world
Makes the world
We need electricity yeah

SONG: "Electricity" by Teacher and the Rockbots
LYRICS
Robot: What has no color, weight or smell, and is all around us?
Electricity, electricity
Iron, steel or nickel, it's made with one of these
Makes the dial of a compass point North with ease
It has two poles: positive and negative
The Earth is one too and they're everywhere we live
Teacher: It's a MAGNET. You can find one in a speaker.
Electrons and ions attract and repel
Positively shocking; the negative's a yell (yow!)
Chemicals can do the same in a battery
The world is a better place with this discovery
Teacher: It's an ELECTRIC CHARGE!
The electric company uses this machine
Powered by coal or other source of energy
Moving wires and magnets in a big way
Supply electric current every single day
Teacher: It's a GENERATOR!
Robot: Let's review
The natural force of a magnet is free,
But how does this metal make electricity?
Wrap wires around it move it with a machine,
This can generate electricity!
Did you know that your brain and muscles need a very small amount of electricity to work?
Robot: I need electricity too!
But be careful with the large amounts of electricity around your house
Robot: It will cook your goose!
He flew a kite with a metal key in 1752
He was interested in what lightning could do
Inventor of the lightning rod, a safety device
Protecting people from electric shock was very nice
Teacher: Thank goodness for BENJAMIN FRANKLIN.
A famous inventor that made a better light
A bulb with carbon filament that burned nice and bright
He designed a power system first used in New York City
Electric wires into homes, a brand new industry
Teacher: He also invented the phonograph... it's THOMAS EDISON.
It starts to flow when you switch on a light
If the circuit's path is closed and wired up right
It passes through conductors like metal or water
But not through plastic or another insulator
Teacher: That's an ELECTRIC CURRENT... I don't want that in my body.
Robot: Let's review again
Electricity - Ben Franklin and a kite
Electricity - Thomas Edison and a light
Electricity - you need to treat it right
Electricity - a shock with a killer bite
