The woman energy worker is guiding
the turbine blades into place. Water is boiled to make
steam. The steam turns the blades of the turbine to generate
electricity.
Girls can be great at science.
Great Hornbill
Have you ever seen a bird like this?
The great hornbill (Bucevos bicornis)
lives in the forests of India and the Himalayas and feeds
mainly on fruit.
When rainforests are cut down to provide cheap wood products
to people in one part of the world, the great hornbills
lose their homes in another part of the world.
Man Talking on Wireless Phone
Do you like to talk on the telephone?
Wireless cellular phones allow people
talk to each other over long distances without being physically
connected by wires. Radio signals are bounced from satellites to buidings and people.
Does the man on the phone know that
he doesn't have to be tied to the telephone pole anymore? Can you find the blue radio signals coming from the skyscraper in the mural?
Coal
We make electricity by burning coal.
This pile of coal will be burned
to turn water into steam. The steam will turn turbine
blades (see the woman energy worker above) to make electricity
for homes and transportation (like the train below). Burning
coal is a leading cause of air pollution; many people
are adopting cleaner energy sources like wind and the
sun.
Train
Have you ever been on a train?
Trains help transport people, coal
and food to and from cities and farms.
Where are
the people riding the train going—to home, to work,
to school?
Toaster and Toast
Do you like to have toast with breakfast?
Stainless steel toasters like this
one use electricity to turn bread into toast. The toast
in the toaster was made from wheat from the farmland.
