Question:
How do consumer goods get from the
Earth to our hands?

Question:
I just bought a radio and I want to know
where the materials used to make it come
from.
Where Challenge
I took the radio apart and saw some really
cool stuff. Wonder what it is and what its
made from?
Where Challenge
So…… I asked my teacher…..
Where Challenge
Well the items you brought in Johnny are
a transformer, resistor and integrated
circuit.
Transformer
Resistor
Integrated Circuit
Where Challenge
Well what are those things, and what are
they made out of?
Where Challenge-Transformer
A transformer is a device that transfers
electric energy from one circuit to another
through electrical conductors.
It’s made of steel, plastic, iron, and copper.
Where Challenge
• But where do they come from?
Where Challenge-Copper
• Well I know that most copper comes from
Chile, U.S.A and Canada.
Where Challenge-Iron
• Iron is mined a lot in Canada and India.
Iron is used 98% of the time for steel so
whenever you are mining iron you are
basically mining steel.
Where Challenge-plastic
• Plastic is a manmade substance made from oil.
Oil can be found in many places all around the
world. Some big oil wells are found in the U.S,
Canada, Saudi Arabia, and Iran.
Where Challenge
• Well what about an integrated circuit?
Where Challenge-Integrated Circuit
• An Integrated Circuit is kind of like a chip.
Like the motherboard in your computer.
• It’s made of Aluminum, Silicon, and
copper.
Where Challenge-Aluminum
• Aluminum is found in Canada, Australia,
Brazil, Guinea, Jamaica, Ghana, Indonesia,
Russia and Surinam.
Where Challenge- Silicon
• Silicon is found in the U.S, Iceland,
Norway, Russia, Brazil and Canada.
Where Challenge- Resistor
• A resistor is a electric circuit component
designed to oppose an electric current.
• It’s made of ceramic, carbon film and
nickel chromium.
Where Challenge
• Well where can we find nickel chromium
and all that stuff?
Where Challenge-Nickel-Chromium
• Nickel-Chromium is composed of 80%
Nickel and 20% Chromium.
• Major Nickel production sites are found in
Canada, Russia and New Caledonia.
Where Challenge-Chromium
• Chromium can be found in South Africa.
Where Challenge- Ceramic
• The ceramic in a resistor is made of aluminum
•
oxide.
Major Aluminum oxide plants are found in
Canada, Spain, Portugal ,Italy, Australia,
Kazakhstan and Japan.
Where Challenge-Carbon film
• Carbon film is composed mainly of carbon with some
•
graphite. Carbon is a natural resource and is found
almost everywhere.
The most major graphite producers are China, India,
Brazil and North Korea.
Summary
Well Johnny now you know “WHERE”
these things come from.
Wow thanks that was really cool and
was fun!
